Description

TECHNICAL FIELD

[0001] The present application relates to the field of loudspeaker design, in particular to a quick-heating storage water type air conditioner water heater system and a heating control method thereof. BACKGROUND

[0002] As a product for moving heat, heat pump produces several times of energy product with a small amount of energy consumption, which will be a future development direction. However, due to its own limitations, there are some deficiencies.

[0003] (1) Air conditioner is the main product of heat pump. The early air conditioner water heater uses heat recovery series mode, which needs to turn on the air conditioner to have hot water. Moreover, the refrigerant is affected by the environment temperature, and the amount of refrigerant is more or less. The opening of the electronic expansion valve and the storage tank cannot meet the demand of refrigeration and heating, and the energy efficiency ratio of the air conditioner is greatly affected. The late air conditioner water heater uses two-supply parallel mode to solve the hot water and solve the problem of more or less refrigerant. However, the key component check valve liquid path is smooth, the gas path is hindered, which affects the energy efficiency ratio of the air conditioner. The three-way valve is used to solve the gas path hindrance, and the energy efficiency ratio is unchanged, like the air conditioner.

[0004] (2) The existing water heater is not instant or storage type. The instant storage type air conditioner water heater integrates the advantages of instant or storage type and air energy water heater low temperature and high efficiency, and improves and perfects the new type of water heater.

[0005] (3) Air energy water heater is divided into three categories according to heating mode: fluorine cycle, water cycle and direct heating machine. Oxygen cycle can be used for heat recovery. In the actual application process of water cycle machine, the energy efficiency ratio is only half of the mark. The energy efficiency ratio of the heating machine is consistent with the mark. The energy efficiency ratio of the single direct heating machine is relatively low due to large temperature difference. The energy efficiency ratio of the double direct heating and water cycle composite heating is relatively high.

[0006] (4) Non-pressure water tank water level control is unstable

[0007] Most of the water level control of air energy water heater adopts liquid level control, and a few adopts floating ball. With the progress of science and technology, the stability of the product is improved year by year, and the water level control is the most prone to failure device in commercial machine.

[0008] Now the circuit board with three line level controller, but because the circuit board level control sensitivity is not high, after a period of time will appear water tank full of water or not into the phenomenon, so the commercial air energy water heater all use independent water level controller control water, the water level controller on the Internet, there are dedicated water level controller, ball and the recently adopted electronic water level switch, the final result is to use on-off control circuit board water level switch, in addition to the single ball float switch (easy to water) by buoyancy and gravity, is to use the upper, middle, lower three point water level control water, mechanical water is also prone to failure.

[0009] In the application process, the proportion of three-point water level control water accounts for the vast majority, so the three-point water is used, and the single-point control on-off is due to the fluctuation of water surface, which leads to the on-off of single-point on-off, poor stability, causing the components to be damaged. Solution: when the water level rises to the on-off point signal, continue to water until the on-off point is not affected by the water surface fluctuation.

[0010] (5) Conversion of direct heating machine and water circulating machine

[0011] Water circulating machine is cold water directly into the water tank and hot water mixing, temperature drop 5 degrees main machine start heating, the equipment always works in high temperature area, low energy efficiency ratio.

[0012] Direct heating machine is cold water directly into the cold suspecter to heat to the set temperature before entering the water tank, relying on water level control equipment to start, at this time the circulating water pump does not work, relying on the pressure of tap water to complete the circulating heating. But because the pressure of tap water is not stable, sometimes there will be water phenomenon, leading to frequent equipment failure, many businessmen do not like to install direct heating machine, even if the heating machine is installed, it is changed to water circulating machine, so the market share of energy-saving direct heating machine is very small.

[0013] The solution to the instability of direct heating machine is to use water pressure or water flow control at the water inlet. When the pressure is low or the water flow is lower than a certain value, it will be converted to water circulating heating. When the pressure is high and the water flow is large, it will be converted to direct heating, without failure, stability like water circulating machine.

[0014] (6) Energy efficiency ratio of direct heating machine and double direct heating machine

[0015] Direct heating machine uses cold water to heat directly to hot water, with large temperature difference, relatively low energy efficiency ratio, especially in cold season, the temperature difference is larger, the energy efficiency ratio is lower. Double direct heating uses two-stage direct heating, the temperature difference is reduced by half, the energy efficiency ratio is relatively high. And the temperature of the first direct heating is often set at the return water temperature, reducing the cooling of high temperature water by return water, fully utilizing the energy of high temperature water and return water temperature difference, the second direct heating is the water tank temperature, plus the heating of heat pump to provide hot water for users, the energy efficiency ratio is higher, and the heat preservation loss of water tank is reduced, the use cost is lower.

[0016] (7) Commercial air energy water heater start mode.

[0017] The starting mode of the conventional air energy water heater mainly includes:

[0018] 1) Temperature drop start, the water temperature probe senses the water tank temperature, and when the temperature is lower than the set temperature by 5 degrees, the host starts heating.

[0019] 2) Water level start, when the device uses direct heating, the water level decreases, and the water inlet starts.

[0020] 3) Double temperature difference start, the temperature difference between the top of the water tank and the low end of the water tank causes the device to start.

[0021] In view of the deficiencies in the prior art, further improvement is needed. SUMMARY

[0022] The present application provides a kind of instant water storage type air conditioner water heater system and heating control method thereof, which can reduce energy consumption, help reduce use cost and save energy.

[0023] The specific technical scheme of the present application is as follows:

[0024] The present application provides a kind of instant water storage type air conditioner water heater system, which includes a control system, and a compressor, an indoor unit and an outdoor unit electrically connected to the control system. The compressor is connected to the D port of a four-way valve. The S port of the four-way valve is connected to a gas-liquid separator. The E port of the four-way valve is connected to the outdoor unit. The outdoor unit is connected to a condenser heat exchanger through a hot water electronic expansion valve and a fluorine path check valve. The hot water electronic expansion valve is connected to the outdoor unit through an air conditioner electronic expansion valve. The indoor unit is connected to the C port of the four-way valve through the first interface and the second interface of a three-way valve. The third interface of the three-way valve is connected to the first connection end of the condenser heat exchanger. The fourth connection end of the condenser heat exchanger is connected to the fluorine path check valve. The water outlet and the water inlet of the condenser heat exchanger are connected to a water tank.

[0025] Further, the water tank includes a pressure-bearing water tank and a non-pressure-bearing water tank,

[0026] The water circuit of the pressure-bearing water tank includes a circulating water pump connected to the bottom end of the pressure-bearing water tank, a circulating electromagnetic valve, a water inlet of the condenser heat exchanger and a hot water check valve. The output end of the condenser exchanger is connected to a pipeline electric heating. The pipeline electric heating is connected to a user and a circulating check valve. The circulating check valve is connected to the pressure-bearing water tank.

[0027] The water heating waterway of the pressure tank includes the water flow switch, one end of the water flow switch is connected with tap water, the other end is connected with the bottom end inlet of the circulating water pump and the pressure tank, the top end outlet of the pressure tank is connected with the hot water check valve, the hot water check valve is connected with the circulating electromagnetic valve and the input port of the condensing heat exchanger, the waterway output port of the condensing heat exchanger is connected with the pipeline electric heating, the pipeline electric heating is connected with the circulating check valve and the user water, the user water is returned to the water flow switch inlet and the tap water inlet through the return water pump, the return water electromagnetic valve and the return water check valve, and the return water is completed.

[0028] Further, the bottom end interface part of the non-pressure tank is connected with the circulating water pump through the one-way valve, the circulating water pump is connected with the waterway input end of the condensing heat exchanger input end, the one-way valve is sequentially connected with the water inlet control electromagnetic valve, the pressure control switch and the water flow control switch,

[0029] The waterway output end of the condensing heat exchanger is connected with the hot water output end of the non-pressure tank, the hot water output end of the non-pressure tank is further connected with the automatic pressure pump, and the output end of the automatic pressure pump is returned to the non-pressure tank through the return water control electromagnetic valve after being used by the user.

[0030] Further, the non-pressure tank is internally provided with a dry reed tube floating ball, the dry reed tube floating ball is connected with the input end of the control system, and the control system stops water inlet after receiving the on-off signal of the dry reed tube for 2-60 minutes (adjustable).

[0031] Further, the hot water output end of the non-pressure tank is connected with the automatic pressure water pump, the connecting pipe connected with the output end of the condensing heat exchanger has a smaller pipe diameter than the connecting pipe connected with the hot water output end of the non-pressure tank. The control system of the automatic pressure pump is connected with a power supply, the voltage or current signal of the automatic pressure pump start is connected with the input end of the control system, and the rapid synchronous start is met.

[0032] Further, the pressure control switch is connected with the input end of the control system, the pressure control switch is turned off when the water pressure is lower than 0.05 Mpa, the control system is switched to the water circulation heating mode, the pressure control switch is turned on when the water pressure is higher than 0.15 Mpa, and the control system is switched to the direct heating mode.

[0033] The cold water inlet control switch is a Hall effect flow switch, connected to the input terminal of the control system. When the control system receives a continuous pulse signal from the flow control switch, the device starts. The flow control switch can also measure the water volume. The flow is measured according to different sizes and pulse signals. When the water flow is less than 10-30% (adjustable) of the rated value, the Hall effect flow switch switches to water circulation heating mode. When the flow is greater than or equal to 10-30% (adjustable) of the rated value, it switches to direct heating mode.

[0034] The water flow control switch is connected to the control system for quantitative water intake. The water flow control switch rapidly changes the operating frequency of the control system according to the rapid changes in flow rate.

[0035] A heating control method for an instantaneous storage-type air conditioning water heater system includes the following steps:

[0036] S1: Temperature drop start

[0037] When the water temperature is 5℃ lower than the set temperature (adjustable), the main unit starts heating; once the set temperature is reached, the main unit stops heating.

[0038] S2: Water intake start

[0039] When the Hall flow switch pulses work continuously, the four-way valve is first energized (adjustable from 2 to 10 seconds) to balance the high and low pressures before being de-energized, and then the compressor is started. This avoids starting under load and damaging the compressor. The Hall flow switch is extremely sensitive; even a slight movement of the water flow in the pipe will cause the equipment to start. It can only start after receiving a continuous pulse signal.

[0040] S3: Water supply started

[0041] When the automatic booster pump is working, the voltage or current signal of the automatic booster pump is connected to the input terminal of the control board, and the equipment starts up quickly. The water supply temperature is the sum of the water tank temperature and the temperature increased by the heat pump.

[0042] S4: Intelligent Control

[0043] S41: The circuit board controls the equipment via a remote communication module on a mobile phone, flat panel, and computer, and monitors and controls the equipment's working status via GPRS, implements status tracking, and performs remote maintenance and early warning.

[0044] S42: The circuit board uses a current sensing coil to test the operating current, power and power consumption of the equipment. The Hall effect water flow switch can obtain the water flow rate and control the water intake. Mobile phones, tablets and computers can see the real-time water consumption and power consumption.

[0045] S43: Intelligent Water Temperature Control

[0046] The water tank temperature is controlled by the ambient temperature: when the ambient temperature is greater than 30 degrees, the maximum water tank temperature is 45 degrees; when the ambient temperature is greater than 25 degrees and less than 30 degrees, the maximum water tank temperature is 50 degrees; and when the ambient temperature is less than 25 degrees, the maximum water tank temperature is 55 degrees. When the water tank temperature is set to be high, the system automatically reduces the maximum temperature according to the ambient temperature. When the water tank temperature is set to be lower than the maximum temperature, the system works according to the set temperature. The temperature is automatically increased or decreased according to the change of the ambient temperature.

[0047] S44: high-temperature sterilization or rapid storage of hot water

[0048] When the water tank temperature is set to be high, the low-temperature section of the heating water tank can be heated by the air energy heat pump alone or by the pipeline electric heating. When the temperature exceeds 55 degrees, only the pipeline electric heating is used until the set temperature is reached. When the water tank temperature is greater than 55 degrees, only the pipeline electric heating works. When the water tank temperature is less than or equal to 55 degrees, the air energy water heater resumes work, and the pipeline electric heating also works. The heating temperature of the pipeline electric heating is set according to the user's needs.

[0049] Further, for the pressurized water tank instant storage water circulation heating mode

[0050] When the water temperature drops, the main unit starts, the low-end outlet water of the pressurized water tank is pressurized by the circulating water pump, and then sent to the cold suspect input end through the circulating electromagnetic valve. The other end of the input end is connected to the hot water check valve, and the circulating water cannot pass through. The cold suspect is heated through the heat exchanger, and then heated by the pipeline electric heating to return to the water tank through the circulating check valve, completing the circulation heating. The heating of the pipeline electric heating is controlled by the ambient temperature, the water tank temperature, and the water flow switch. The other end of the output port is blocked by the backwater electromagnetic valve, and cannot form a loop.

[0051] When the user uses hot water, the water flow switch works, and the equipment starts. The circulating water pump and the circulating electromagnetic valve do not work. Under the pressure of the tap water, the water tank water is sent to the cold suspect input end through the hot water check valve at the top outlet, and is directly heated to the output end through the cold suspect heat exchanger, and then is heated by the pipeline electric heating for the user to use. The other end of the cold suspect outlet is connected to the circulating check valve, and cannot flow due to the low water pressure.

[0052] For the pressurized water tank instant storage water circulation heating mode, specifically:

[0053] When the user uses water, the water flow switch works, and the backwater pump and the backwater electromagnetic valve work simultaneously. The equipment starts, and the hot water is pressurized by the backwater pump and returns to the input port of the bottom of the water tank, completing the backwater circulation. The circulation time is set according to the length of the backwater pipe (adjustable from 2 to 20 minutes). The backwater electromagnetic valve is added to avoid the second circulation loop, which causes the water flow switch to work incorrectly and causes the equipment to frequently switch.

[0054] For the pressure tank, the intelligent control mode of the instant water heating type is as follows:

[0055] In addition to the start device signal, the Hall water flow switch adds the measurement of water flow. According to different specifications, the number of pulses of the water flow switch is calculated to control the water quantity. The variable frequency device can be quickly controlled by the variable flow signal of the water flow switch.

[0056] The pipeline electric heating is controlled by the ambient temperature below 0-40 degrees (adjustable) to meet the rapid heating of the water tank of the water circulating machine and the higher water temperature output of the direct heating machine, while meeting the demand for large water quantity and high temperature sterilization in cold seasons. When the water temperature of the water tank exceeds the highest working water temperature of the air energy water heater, it switches to separate pipeline electric heating work until the set temperature is reached.

[0057] Further, for the water level control of the non-pressure tank, the specific control is as follows:

[0058] The water level control of the circuit board is to control the water level by the conductivity of the liquid. At present, a single on-off controller is used to control the water level without relying on the conductivity of the liquid, but relying on the buoyancy control on-off, such as stainless steel reed tube float switch. The magnetic field is controlled by the buoyancy to make the reed tube on-off. In order to avoid the misoperation of the reed tube, when the reed tube is connected or disconnected, the water inlet is continued for 2-60 minutes (adjustable) before stopping. When the reed tube is disconnected or connected, the water inlet starts again until the reed tube works and the water inlet time is delayed before stopping.

[0059] For the water inlet control of the non-pressure tank, the specific control is as follows:

[0060] The water inlet control of the non-pressure tank is usually controlled by the water level and temperature, and the timing control is also used. The circuit board increases the water inlet time for 24 hours timing control. According to the time of heating hot water, the time of high ambient temperature is selected to heat hot water to save electricity,

[0061] The supply water control uses the supply water temperature which is the sum of the water tank temperature and the cold temperature. During the supply water period, the direct heating cold water is stopped. The circulating heating is used to supply hot water. Since the water quantity cannot be accurately controlled, the hot water higher than the water tank temperature returns to the water tank. When the water tank temperature is higher than the set temperature by 10 degrees (adjustable), the device does not work when hot water is used.

[0062] The direct heating machine adopts proportional regulating valve to control the water temperature, and the proportional regulating valve is removed, and manual adjustment is adopted, and the precision is insufficient, so the direct heating heating must have the water temperature adjusting function of the water circulating machine, and in the direct heating heating process: when the water tank temperature exceeds the set temperature, heating is stopped, and cold water is continuously added. When the water tank temperature is lower than the set temperature (5 degrees adjustable), stop adding water, and switch to water circulation heating, and when the set temperature is reached, switch to direct heating mode heating until the water is full. After the water is full, if the set temperature is not reached, switch to water circulation heating, and stop heating when the set temperature is reached.

[0063] The water quantity control adopts water level total water quantity limitation and Hall water flow metering control, and the water quantity is controlled according to the real-time use of hot water quantity or the hot water quantity required at a certain time;

[0064] The water quantity control direct heating and water circulation conversion specific way is:

[0065] The direct heating machine relies on the pressure of tap water to heat hot water, and when the water pressure is low or the water stop time, the equipment stops working by high pressure protection or exhaust temperature protection, and needs to be manually restored. The water flow is controlled by a Hall water flow switch, and when the water flow is greater than a certain set value, the direct heating machine is used, and when the water flow is less than a certain set value, the water circulation heating is used. When the water flow is greater than the set value, the direct heating machine is restored to heat until the water tank is full,

[0066] The pressure control of cold water controls the direct heating and water circulation conversion: when the water pressure reaches a certain value, the direct heating mode is used, and when the set value is lower than the set value, the circulation heating is converted to the direct heating mode, and the direct heating mode is converted to the direct heating mode until the water tank is full.

[0067] For the pressurization and backwater control of the non-pressure water tank, the specific way is:

[0068] The hot water pressurization adopts the working voltage or current of the automatic booster water pump as the working signal of the equipment, the working voltage is converted into an on-off signal, and the working current is converted into a low-voltage working signal through a mutual inductor,

[0069] And the size of the hot water supply port is increased compared with the size of the hot water inlet port, which avoids the lack of water protection of the equipment and causes the fault,

[0070] The backwater adopts a backwater electromagnetic valve to control the backwater quantity, and when the automatic water pump works, it provides a starting signal for the equipment, so that the water supply temperature is the water tank temperature plus the equipment rising temperature. At the same time, the on-off time of the backwater electromagnetic valve can be set according to the backwater quantity.

[0071] Further, the instant hot water storage type air conditioner water heater system is a cold, warm and hot three-in-one product, and is also a mixed product of water circulating machine, direct heating machine and double direct heating machine, and various controls have priority work:

[0072] 1) When the air conditioner is working, and hot water is needed, hot water is given priority.

[0073] 2) When the device is heating hot water, the user uses hot water, and instant heating is given priority.

[0074] 3) When the air conditioner or hot water heating is working, defrosting is stopped as soon as the user uses hot water, and instant heating is given priority.

[0075] The beneficial effects of the present application are:

[0076] The instant water storage type air conditioner water heater system and heating control method provided by the present application have the advantages of low energy consumption, which helps to reduce the use cost and save energy, and the specific advantages are as follows:

[0077] 1) The present application adopts a unique design idea of instant water storage type air conditioner water heater fast start and refrigerant passage, and the air conditioner is increased with an instant water storage type water heater. In addition to considering the instant water storage type fast start and the high and low pressure balance of the refrigerant, the refrigeration and heating of the air conditioner cannot be affected. Therefore, the cold pipe of the four-way valve is connected to the input end of the three-way valve, the constant output port of the three-way valve is connected to the cold doubler, and after heat exchange through the cold pipe, the fluorine road check valve, the hot water electronic expansion valve, and the outdoor unit.

[0078] 2) Unique system working priority setting

[0079] 1) When the air conditioner is working, and hot water is needed, hot water is given priority.

[0080] 2) When the device is heating hot water, the user uses hot water, and instant heating is given priority.

[0081] 3) When the air conditioner or hot water heating is working, defrosting is stopped as soon as the user uses hot water, and instant heating is given priority.

[0082] 4) Cold and hot water temperature difference start; adopt double temperature probe, which usually senses the water tank temperature, and senses the cold water temperature when cold water is added, and starts with temperature difference.

[0083] 5) Backwater temperature difference start: adopt double temperature probe, which usually senses the water tank temperature, and senses the backwater temperature when backwater is added, and starts with temperature difference.

[0084] 3) Unique and novel switch control mode

[0085] In addition to the function of starting the device when water flows, the water flow switch also has the following functions.

[0086] 1) The size of the water flow switch and the pulse number of the Hall water flow switch determine the water flow, so that the user can know the amount of hot water used every day, every month, and every year.

[0087] 2), water flow switch metering, according to the daily hot water demand, control the water inlet solenoid valve.

[0088] 3), water flow switch flow size is the signal of direct heating and water circulating machine conversion, when the water flow per unit is less than a certain value, it is converted to water circulating machine operation, when the water flow per unit is greater than a certain value, it is converted to direct heating machine operation, until the water is full and the machine stops.

[0089] 4), water flow switch flow control frequency converter, when the water flow is stable, the water temperature probe controls the frequency of the frequency converter, and the water flow switch controls the frequency of the frequency converter when the water flow changes rapidly.

[0090] 4, unique automatic pressure pump start and backwater mode

[0091] In addition to pressurizing hot water, the automatic pressure pump can also use voltage and current signals to quickly start the air energy water heater, avoiding the problems of increasing the cost of water flow switch, inaccurate control and limited flow. Control method: when the automatic pressure pump is pressurized, the voltage becomes an on-off signal through an intermediate relay, and the current becomes a working signal through a transformer to control the start of the air energy water heater. At the same time, it also controls the working time of the backwater solenoid valve. The working time of the backwater solenoid valve can be determined according to the length of the backwater pipe and the amount of water to determine the backwater time. When working for the second time, the interval time should be more than 15 minutes.

[0092] 5, unique automatic water supply pressure pump water shortage control and system control method

[0093] The traditional air energy water heater has a higher hot water supply outlet than the circulating outlet, which will not cause the equipment to malfunction due to lack of water. The double direct heating air energy water heater uses the superposition of the water supply temperature, which is the temperature of the water tank plus the temperature rise of the heating pump, and the hot water circulating outlet is connected to the inlet of the water supply pressure pump. If the pipe diameter of the hot water outlet is the same as that of the hot water circulating outlet, it will cause water shortage and cause equipment failure. Therefore, the pipe diameter of the hot water supply outlet should be greater than that of the hot water circulating outlet. When the water tank is short of water, the water flow of the hot water circulating outlet flows into the water tank, and the water supply pump stops working due to lack of water, protecting the equipment and avoiding failure.

[0094] The water inlet of the equipment is affected by multiple factors,

[0095] 1), water level control, which is also the maximum water capacity.

[0096] 2), timing water, which can be selected for a certain period of time, which can be divided into several sections.

[0097] 3), water flow switch metering, according to the daily hot water demand, control the water inlet solenoid valve.

[0098] 4), the second direct heating, to avoid mixing water, stop water.

[0099] 5), for quick defrosting, stop water during defrosting.

[0100] 6, the single stainless steel ball float dry reed tube is a good choice, because the on-off is controlled by magnetic force due to the buoyancy, and the micro-current of on-off has little effect on the dry reed tube, the service life of the dry reed tube is nearly one hundred million times, and the stability is strong.

[0101] 7, the application adopts a plurality of starting modes

[0102] 1), water flow switch: when the water flow is on, the host starts heating.

[0103] 2), pressurized voltage signal: when the pressurized water pump works, the voltage signal is converted into an on-off signal to start the equipment.

[0104] 3), pressurized current signal: when the pressurized water pump works, the coil current is inducted to start

[0105] 8, the direct heating water control of the non-pressure water tank is controlled by the water tank temperature, the traditional direct heating machine has high cost and is prone to failure due to complex control and expensive proportional regulating valve. Now the water flow switch directly controls the water, the control precision is not high, the direct heating water temperature is lower than the water tank temperature, when the water tank temperature is lower than the set temperature by 5° (adjustable), the water stops, and the equipment is converted into water circulation heating. When the water tank temperature reaches the set temperature, the water inlet electromagnetic valve works to supply water, and the equipment is converted into direct heating until the water tank is full. The direct heating and circulation mode has higher energy efficiency than the single heating mode.

[0106] Compared with the traditional technology, the application effectively reduces the use cost, and also makes great contribution to energy saving and emission reduction of human society, so that the application has great social value and economic value. BRIEF DESCRIPTION OF DRAWINGS

[0113] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. The drawings are for reference and illustration only and do not constitute a limitation on the scope of protection of the present invention.

[0114] Example 1

[0115] like Figures 1-2 As shown, this embodiment specifically describes the pressurized water tank. This embodiment provides an instant hot water storage air conditioning water heater system, including a control system, and a compressor, an indoor unit, and an outdoor unit electrically connected to the control system. The compressor is connected to the D port of a four-way valve, the S port of the four-way valve is connected to a gas-liquid separator, and the E port of the four-way valve is connected to the outdoor unit. The outdoor unit is connected to a condensing heat exchanger through a hot water electronic expansion valve and a refrigerant check valve.

The water output end and water input end of the condensing heat exchanger are connected to a water tank.

[0116] The water circuit for heating the pressurized water tank includes a circulating water pump connected to the bottom of the pressurized water tank, which is then connected to a circulating solenoid valve.

The user's water supply is pumped back, then passes through the return solenoid valve and the return check valve, and then returns to the inlet of the flow switch and the tap water inlet to complete the return process.

[0118] Furthermore, the pressure control switch is connected to the input terminal of the control system. When the water pressure is lower than 0.05 MPa, the pressure control switch is turned off, and the control system switches from direct heating mode to water circulation heating mode. When the water pressure is higher than 0.15 MPa, the pressure control switch is turned on, and the control system switches to direct heating mode.

[0119] The cold water inlet control switch is a Hall water flow switch, which is connected to the input end of the control system. When the control system receives the continuous pulse signal of the water flow control switch, the device starts. The water flow control switch can also measure the water volume. According to different sizes and pulse signals, the water volume is measured. When the water flow is less than 10-30% (adjustable) of the rated value, the Hall water flow switch changes to the water circulation heater mode. When the water flow is greater than or equal to 10-30% (adjustable) of the rated value, it changes to the direct heating mode.

[0120] The water flow control switch is connected to the control system for quantitative water inlet. The water flow control switch quickly changes the operating frequency of the control system according to the rapid change of the flow.

[0121] A heating control method of an instant water storage type air conditioner water heater system, comprising the following steps:

[0122] S1: temperature drop start

[0123] When the water temperature is lower than the set temperature by 5℃ (adjustable), the host starts heating, and stops heating when the set temperature is reached.

[0124] S2: water inlet start

[0125] When the Hall water flow switch pulse works continuously, the four-way valve is powered on first (2-10 seconds adjustable), and then the compressor is started after the high and low pressure is balanced, so as to avoid damage to the compressor caused by starting with load. The sensitivity of the Hall water flow switch is very high, and the micro motion of the water flow in the pipe will cause the device to start. It can only start after receiving continuous pulses.

[0126] S3: water supply start

[0127] When the automatic pressure pump works, the voltage or current signal of the automatic pressure pump is connected to the input end of the control panel, and the device starts quickly. The water supply temperature is the superposition of the water tank temperature and the temperature rise of the heat pump.

[0128] S4: intelligent control

[0129] S41: The line board controls the device through the remote communication module in the mobile phone, flat paddle and computer, and monitors and controls the working state of the device through GPRS, implements the follow-up state and remote maintenance and early warning;

[0130] S42: The line board tests the working current, power and power consumption of the device through the current induction coil. The Hall water flow switch can get the water flow and control the water inlet volume. The mobile phone, flat paddle and computer can see the real-time water consumption and power consumption;

[0131] S43: water temperature intelligent control

[0132] The water tank temperature is controlled by the ambient temperature: when the ambient temperature is greater than 30 degrees, the maximum water tank temperature is 45 degrees; when the ambient temperature is greater than 25 degrees and less than 30 degrees, the maximum water tank temperature is 50 degrees; and when the ambient temperature is less than 25 degrees, the maximum water tank temperature is 55 degrees. When the water tank temperature is set to be high, the system automatically reduces the maximum temperature according to the ambient temperature. When the water tank temperature is set to be lower than the maximum temperature, the system works according to the set temperature. The temperature is automatically increased or decreased according to the change of the ambient temperature.

[0133] S44: high-temperature sterilization or rapid storage of hot water

[0134] When the water tank temperature is set to be high, the low-temperature section of the heating water tank can be heated by the air energy heat pump alone or by the pipeline electric heating. When the temperature exceeds 55 degrees, only the pipeline electric heating is used until the set temperature is reached. When the water tank temperature is greater than 55 degrees, only the pipeline electric heating works. When the water tank temperature is less than or equal to 55 degrees, the air energy water heater and the pipeline electric heating work. The heating temperature of the pipeline electric heating is set according to the user's needs.

[0135] In this embodiment, for the pressurized water tank, the water circulation heating mode is

[0136] When the water temperature drops, the main unit starts, the outlet water of the low-end of the pressurized water tank is pressurized by the circulating water pump, and then sent to the input end of the cold suspect through the circulating electromagnetic valve. The other end of the input end is connected to the hot water check valve, and the circulating water cannot pass through. The cold suspect is heated through the heat exchanger, and then heated by the pipeline electric heating to return to the water tank through the circulating check valve, completing the circulation heating. The heating of the pipeline electric heating is controlled by the ambient temperature, the water tank temperature, and the water flow switch. The other end of the output port is blocked by the backwater electromagnetic valve, and cannot form a loop.

[0137] When the user uses hot water, the water flow switch works, the equipment starts, and the circulating water pump and the circulating electromagnetic valve do not work. Under the pressure of the tap water, the water tank water is sent to the input end of the cold suspect through the hot water check valve from the top outlet, directly heated by the cold suspect heat exchanger, and then heated by the pipeline electric heating for the user to use. The other end of the cold suspect outlet is connected to the circulating check valve, and cannot flow due to the lower water pressure than the water tank pressure.

[0138] For the pressurized water tank, the backwater heating mode is as follows:

[0139] When the user uses water, the water flow switch works, the backwater pump and the backwater electromagnetic valve work at the same time, the equipment starts, and the hot water returns to the input port of the bottom of the water tank from the top outlet of the water tank under the pressure of the backwater pump, completing the backwater circulation. The circulation time is set according to the length of the backwater pipe (adjustable from 2 to 20 minutes). The backwater electromagnetic valve is added to avoid the second circulation loop, which may cause the water flow switch to work incorrectly and cause the equipment to frequently switch.

[0140] For the pressure tank, the intelligent control mode is as follows:

[0141] In addition to the start signal of the device, the Hall water flow switch adds the measurement of water flow. According to different specifications, the number of pulses of the water flow switch is calculated to control the water quantity. The variable frequency device can quickly control the frequency of the device by using the variable flow signal of the water flow switch.

[0142] The pipeline electric heating is controlled by the ambient temperature below 0-40 degrees (adjustable) to meet the rapid heating of the water tank of the water circulating machine and the higher water temperature output of the direct heating machine, while meeting the demand for large water quantity and high temperature sterilization in cold seasons. When the water temperature of the water tank exceeds the highest working water temperature of the air energy water heater, it switches to separate pipeline electric heating work until the set temperature is reached.

[0143] The instant hot water storage type air conditioner water heater system is a three-in-one product of cooling, heating and hot water, and a mixed product of water circulating machines, direct heating machines and double direct heating machines. Various controls have priority work:

[0144] 1) When the air conditioner is working, if hot water is needed, hot water has priority;

[0145] 2) When the device is heating hot water, if the user uses hot water, instant heating has priority;

[0146] 3) When the air conditioner or heating hot water is working, if the user uses hot water, the defrosting is stopped immediately and instant heating has priority.

[0147] Embodiment 2

[0148] As shown in Figure 3 The bottom end interface part of the non-pressure tank is connected with a circulating water pump through a one-way control valve, the circulating water pump is connected with the water inlet end of the condenser heat exchanger, and the one-way valve is sequentially connected with a water inlet control electromagnetic valve, a pressure control switch and a water flow control switch.

[0149] The water outlet end of the condenser heat exchanger is connected with the hot water outlet end of the non-pressure tank, and the hot water outlet end of the non-pressure tank is also connected with an automatic booster pump. The output end of the automatic booster pump is connected with the non-pressure tank through a backwater control electromagnetic valve after being used by the user.

[0150] In this embodiment, a reed tube float ball is arranged at the top end inside the non-pressure tank, the reed tube float ball is connected with the input end of the control system, and the control system stops water inlet after receiving the on-off signal of the reed tube for 2-60 minutes.

[0151] In this embodiment, the non-pressure water tank heating water output end is connected to an automatic pressure water pump, and the pipe diameter of the connecting water pipe connected to the condensing heat exchange output end is smaller than that of the connecting water pipe of the heating water output end. The automatic pressure pump control system is connected to a power supply, and the voltage or current signal of the automatic pressure pump start is connected to the control system to meet the rapid synchronous start.

[0152] Further, the input end of the pressure control switch connected to the control system is disconnected when the water pressure is lower than 0.2Mpa, and the control system will be converted to water circulation heating. When the water pressure is higher than 0.4MPa, the pressure control switch is connected, and the control system is converted to direct heating machine,

[0153] The water inlet control switch is a Hall water flow switch connected to the input end of the control system. When the control system receives the continuous pulse signal device of the water flow control switch, the water flow control switch can also measure the water quantity, and the water quantity is measured according to different sizes and pulse signals. When the water flow is less than 30% of the rated value, the Hall water flow switch is converted to a water circulation machine for heating, and when the water flow is greater than or equal to 30% of the rated pool, it is converted to a direct heating machine.

[0154] The water flow control switch is connected to the control system for quantitative water inlet, and the water flow control switch rapidly changes the operating frequency of the control system according to the rapid change of the flow.

[0155] In this embodiment, the water level control of the non-pressure water tank is as follows:

[0156] The water level control of the circuit board is to use high, medium and low liquid level sensors to control the water level by liquid conduction. At present, a single on-off controller is used to control the water level without relying on liquid conduction, but relying on buoyancy control on-off, such as stainless steel dry reed tube float ball switch. The magnetic field is controlled by buoyancy to make the dry reed tube on-off. In order to avoid the misoperation of the dry reed tube, water is continuously supplied for 1-100 minutes (adjustable) after the dry reed tube is connected or disconnected, and then the water supply is stopped. When the dry reed tube is disconnected or connected, the water supply starts again until the dry reed tube is connected and the water supply time is delayed, and then the water supply is stopped.

[0157] The water inlet control of the non-pressure water tank is as follows:

[0158] The water inlet control of the non-pressure water tank is usually controlled by water level and temperature, and the timing control is also used. The water inlet time of the circuit board is controlled by 24-hour timing control. According to the hot water heating time, the heating time of the environment with high temperature is selected to save electricity,

[0159] The water supply control uses the temperature of the water supply, which is the sum of the temperature of the water tank and the temperature of the cold water. During the water supply, the straight hot water is stopped and the cold water is added. The water is heated by the circulation of the straight hot water. Due to the fact that the water consumption cannot be accurately controlled, the hot water that is higher than the temperature of the water tank returns to the water tank. When the temperature of the water tank is higher than the set temperature by 10 degrees (adjustable), the device does not work when hot water is used.

[0160] The water control uses both the water level and the total water volume limit, as well as the Hall water flow meter control. The water inflow is controlled according to the real-time use of hot water, or the hot water needed at a certain time is heated.

[0161] The water control straight hot and water circulation conversion specific way is:

[0162] The straight hot machine relies on the pressure of the tap water to heat the hot water. When the water pressure is low or the water is stopped, the device stops working by high-pressure protection or exhaust temperature protection. It needs to be manually restored. Now, the Hall water flow switch is used to control the water flow. When the water flow is greater than a certain set value, the straight hot machine is used. When it is less than a certain set value, the water circulation heating is used. When the water flow is greater than the set value, the straight hot machine is restored to heat until the water tank is full.

[0163] The pressure control of the cold water straight hot and water circulation conversion: when the water pressure reaches a certain value, the straight hot way is used for heating. When it is lower than the set value, it is converted to circulation heating. Until the pressure value is reached, it is converted to straight hot heating. Until the water tank is full.

[0164] For the pressurization and backwater control of the non-pressure water tank, the specific way is:

[0165] The hot water pressurization uses the working voltage or current of the automatic booster water pump as the device working signal. The working voltage is converted into an on-off signal, and the working current is converted into a low-voltage working signal through a transformer.

[0166] The size of the hot water supply port is increased by using the water shortage protection method of the automatic booster water pump, which is larger than the pipe of the hot water inlet port. This avoids the device water shortage protection and causes the fault.

[0167] The backwater of the device uses a backwater electromagnetic valve to control the backwater amount. When the automatic water pump is working, it provides a start signal for the device, so that the water supply temperature is the temperature of the water tank plus the device rising temperature. At the same time, the on-off time of the backwater electromagnetic valve can be set according to the backwater amount.

[0168] The non-pressure water tank uses the buoyancy, on-off and delayed water inlet method to avoid the stability caused by the conductivity of water. Specifically, a dry reed tube of a stainless steel floating ball switch is used, which has a long service life and high stability.

[0169] The device has the functions of refrigeration, heating and hot water. In terms of working method and defrosting priority:

[0170] Because the refrigeration and heating working time is long, and the hot water working time is short, the hot water heating is given priority, and between the water storage heating and the instant heating, the instant heating is selected.

[0171] In the cold season, the heating and hot water both need defrosting, during the defrosting, as long as the user uses hot water, the defrosting will be stopped, and the instant heating is converted, and when the user finishes using water, the defrosting is converted again.

[0172] The non-pressure water tank adopts the buoyancy, on-off and delayed water inlet mode to avoid the stability caused by the conductivity of water, specifically, a dry reed tube of a stainless steel floating ball switch is adopted, the service life is long, and the stability is high.

[0173] The device with a power of 1.9P selected by the application is tested under different conditions, and the test data are as follows:

[0174] 1. Low water temperature heating capacity test (temperature 15℃-30℃)

[0175]

[0176] 2. Medium-low water temperature heating capacity test (temperature 15℃-40℃)

[0177]

[0178] 3. Medium water temperature heating capacity test (temperature 30℃-40℃)

[0179]

[0180] It is found through the above tests that the application has excellent refrigeration and heating effects in different temperature stages, and the instant water storage type air conditioner water heater system and the heating control method provided by the application have the advantages of low energy consumption, which is helpful to reduce the use cost and save energy, and the specific advantages are as follows:

[0181] 1. The application adopts the unique design idea of instant water storage type air conditioner water heater fast start and refrigerant passage, the air conditioner increases the instant water storage type water heater, in addition to considering the instant water storage type fast start and the refrigerant high-low pressure balance problem, the refrigeration and heating of the air conditioner cannot be affected, therefore, the cold doubt pipe of the four-way valve is connected with the input end of the three-way valve, the constant output port of the three-way valve is connected with the cold doubt device, after heat exchange through the cold doubt pipe, the fluorine road check valve, the hot water electronic expansion valve and the outdoor unit are sequentially connected.

[0182] 2. Unique system working priority setting

[0183] 1) When the air conditioner works, when hot water is needed, the hot water is given priority.

[0184] 2) When the device heats the hot water, the instant heating is given priority when the user uses the hot water.

[0185] 3) When the air conditioner or hot water heating work is defrosting, as long as the user uses hot water, the defrosting is stopped immediately, and the instant heating priority is turned on.

[0186] 4) Cold and hot water temperature difference start; adopt double temperature probe, usually sensing is water tank temperature, cold water temperature sensing when cold water is in, temperature difference start.

[0187] 5) Backwater temperature difference start: adopt double temperature probe, usually sensing is water tank temperature, backwater temperature sensing when backwater is in, temperature difference start.

[0188] 3, unique and novel switch control mode

[0189] The application adopts water flow switch, in addition to the function of starting the device when the water flows, it also has the following functions:

[0190] 1) The size of the water flow switch and the number of pulses of the Hall water flow switch determine the water flow, so that the user can know the amount of hot water used every day, every month and every year.

[0191] 2) The water flow switch can control the water inlet of the water inlet electromagnetic valve according to the daily hot water demand.

[0192] 3) The flow size of the water flow switch is the signal for switching between direct heating and water circulation machine. When the water flow per unit is less than a certain value, the water circulation machine is switched on, and when the water flow per unit is greater than a certain value, the direct heating machine is switched on until the water is full and the machine stops.

[0193] 4) The water flow switch controls the frequency of the frequency conversion machine. When the water flow is stable, the water temperature probe controls the frequency of the frequency conversion machine, and when the water flow changes rapidly, the water flow switch controls the frequency of the frequency conversion machine.

[0194] 4, adopt unique automatic pressure pump start and backwater mode

[0195] In addition to pressurizing hot water, the automatic pressure pump can also use voltage and current signals to quickly start the air energy water heater, avoiding the problems of increasing the cost of water flow switch, inaccurate control and limited flow. Control mode: when the automatic pressure pump is pressurized, the voltage becomes an on-off signal through an intermediate relay, and the current becomes a working signal through a mutual inductor to control the start of the air energy water heater, and also controls the working time of the backwater electromagnetic valve. The working time of the backwater electromagnetic valve can determine the backwater time according to the length of the backwater pipe and the amount of water. When it works for the second time, the interval time should be more than 15 minutes.

[0196] 5, unique automatic water supply pressure pump water shortage control and system control mode

[0197] The traditional air energy water heater's hot water outlet is higher than the circulating outlet, which will not cause the equipment to malfunction due to lack of water. The double direct heating air energy water heater adopts the superposition of the water supply temperature and the heating pump raised temperature, and the hot water circulating outlet is connected to the inlet of the water supply pressure pump. If the pipe diameter of the hot water outlet is the same as that of the hot water circulating outlet, it will cause water shortage and cause equipment failure. Therefore, the pipe diameter of the hot water supply outlet should be greater than that of the hot water circulating outlet. When the water tank is short of water, the hot water circulating outlet flows into the water tank, and the water supply pump stops working due to lack of water, which protects the equipment and avoids failure.

[0198] The water inlet of the equipment is affected by multiple factors,

[0199] 1) Water level control, which is also the maximum capacity of water.

[0200] 2) Timing water inlet, which can select a certain time period for water inlet, which can be divided into several sections.

[0201] 3) Water flow switch metering, which can control water inlet according to the daily hot water demand.

[0202] 4) The second direct heating, in order to avoid mixing water, stop water inlet.

[0203] 5) For rapid defrosting, stop water inlet during defrosting.

[0204] 6, Single stainless steel floating ball reed tube is a good choice, because it relies on buoyancy, on-off relies on magnetic force control, and the micro-current of on-off has little effect on reed tube, and the service life of reed tube is nearly one billion times, and the stability is strong.

[0205] 7, The application combines multiple starting modes

[0206] 1) Water flow switch: when the water flow is on, the host starts heating.

[0207] 2) Pressurized voltage signal: when the pressurized water pump is working, the voltage signal is converted into an on-off signal to start the equipment.

[0208] 3) Pressurized current signal: when the pressurized water pump is working, the coil current is inducted to start

[0209] Compared with the traditional technology, the application effectively reduces the use cost, and also makes great contribution to energy saving and emission reduction of human society, so the application has great social value and economic value.

[0210] The above embodiments are the preferred embodiments of the application, but the embodiments of the application are not limited by the above embodiments, and any changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principles of the application shall be equivalent replacement methods, which are all included in the protection scope of the application.

The cold suspect is heated through the heat exchanger, and then heated by the pipeline electric heating to return to the water tank through the circulating check valve, completing the circulation heating. The heating of the pipeline electric heating is controlled by the working of the environment temperature, the water tank temperature and the water flow switch. The other end of the output port is blocked by the backwater electromagnetic valve, and cannot form a loop. When the user uses hot water, the water flow switch works, the equipment starts, and the circulating water pump and the circulating electromagnetic valve do not work. Under the pressure of the tap water, the water tank water is sent to the cold suspect input end through the hot water check valve from the top outlet, and is heated directly to the output end through the cold suspect heat exchanger, and then is heated by the pipeline electric heating for the user to use.

The variable frequency equipment can quickly control the frequency of the equipment by changing the flow signal of the water flow switch. The pipeline electric heating is controlled by the environment temperature below 0-40 degrees (adjustable) to meet the needs of fast heating of the water tank of the water circulation machine and higher water temperature output of the direct heating machine, as well as the needs of large water volume and high temperature sterilization in cold seasons. When the water tank water temperature exceeds the highest working water temperature of the air energy water heater, only the pipeline electric heating works until the set temperature is reached and the machine stops.

9. The heating control method of the instant storage water type air conditioner water heater system according to claim 7, characterized in that: For the water level control of the non-pressurized water tank, specifically: The water level control of the circuit board is to use high, medium and low liquid level sensors to control the water level by the conductivity of the liquid. The single on-off controller is used to control the water level, which does not rely on the conductivity of the liquid, but relies on the buoyancy to control the on-off. For example, the stainless steel dry reed tube float ball switch uses the buoyancy to control the magnetic field to make the dry reed tube on-off. In order to avoid the misoperation of the dry reed tube, the water is continuously filled for 2-60 minutes after the dry reed tube is connected or disconnected, and then the water filling is stopped. When the dry reed tube is disconnected or connected, the water filling is started again, and the water filling is stopped after the dry reed tube works for a delay time. The water filling control of the non-pressure water tank is as follows: The water filling control of the non-pressure water tank is usually controlled by the water level and temperature, and the timing control is also used. The circuit board increases the water filling time of 24 hours timing control.
