Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning heat pump heating and hot water systems. Background Art

[0002] Indoor air conditioning, hot water and heating are common needs of people, and sustainable development requires energy conservation and low-carbon environmental protection. However, the current household air conditioners produce cold air indoors in summer and emit a large amount of heat energy outdoors, which cannot be used to make hot water, which is a waste of energy. In addition, traditional air conditioners are idle for a long time in spring, autumn and winter in areas with indoor central heating, and the equipment utilization rate is too low, which is also a waste. Researching and developing energy-saving products that can cool and make hot water in summer and use air conditioners as heat pump water heaters in spring and autumn is the dream of people in the refrigeration and heat pump industry. The applicant has applied for and authorized a number of related patents, such as "a dual-effect four-season energy-saving cooling and heating air conditioner and hot water three-in-one machine", patent number: 00264455.x; "a four-season energy-saving cooling and heating air conditioner and hot water three-in-one machine", patent number: 02116049.X ; Currently, a small number of 5-horsepower central air-conditioning triple-supply air-conditioning water heaters are produced on the market, and they still use two four-way valves (one is actually a three-way valve). However, due to the complex structure, many welding points and high failure rate, they have not been widely promoted; the dual-supply system promoted in recent years is popular with "sky fluorine and ground water" and has no special innovation; Although the comfort is good, the project is huge, and the cost of floor heating exceeds that of air-conditioning heat pumps; Due to the large thermal capacity of floor heating, slow start-up and continuous heating, for office workers, the heat of continuous heating is dissipated to the environment through the walls of the house, and the energy-saving effect is greatly reduced; In order to overcome the above-mentioned shortcomings of existing air conditioners and heat pump water heaters, the applicant has accumulated more than 20 years of experience and has applied for several related patents, among which the following have been published: "Summer cooling and winter heating four-season water heater", patent application numbers: 202410732219.4, 202421290011.3, which can be used in principle It can realize both cooling and hot water production in summer, heating and hot water production in winter, and independent air-source heat pump circulation for hot water production in spring and autumn. Hot water is completely free in summer, and hot water in spring and autumn saves more than 72% energy than electric hot water, and 50% energy in winter. However, the technology needs to be improved and the technical solutions need to be innovated; "Integrated cold, warm and hot water multifunctional machine", patent application numbers: 202410953422.4, 202421682569.6, uses cold water for cooling and hot water for heating, extends the cooling and heating space, and adds dehumidification and heating and humidification and heating functions in winter, but its triple water supply circuit is too complicated, which affects its promotion.

[0009] The novel three-purpose cooling and heating air-conditioning water heater, the signal detection control system, the detection signal includes: the hot water temperature Tw of the hot water tank, the indoor temperature Ta and the indoor humidity φ; its characteristics are: the control system implements the principle of hot water priority, according to user needs, only through the transposition of a four-way valve and the start and stop of the outdoor fan, the indoor fan and the circulating water pump associated with the fluorine water-indoor heat exchanger, it can control the heat exchange of the cooling and heating fluorine circuits and whether the fluorine gas is circulated, thereby realizing the control of the four circulation functions and operations of the novel three-purpose machine; the specific control program is: When the four-way valve is in the heating position, there are two refrigerant circuits: 1) the first hot water circulation refrigerant circuit and 2) the heating circulation refrigerant circuit. The operation of these two refrigerant circuits is controlled by starting and stopping the indoor fan and the circulation water pump related to the indoor heat exchanger. When the indoor fan and the circulation water pump stop, the indoor heat exchanger in the heating circulation refrigerant circuit does not exchange heat, and all the refrigerant gas enters the first hot water circulation refrigerant circuit, where the refrigerant condenses and releases heat to produce hot water in the hot water heat exchanger. When the indoor fan and the circulation water pump are running, the outdoor heat exchanger absorbs heat and the indoor heat exchanger provides heating. When the four-way valve is in the cooling position, there are two configured refrigerant circuits: 3) the second hot water circulation refrigerant circuit and 4) the cooling circulation refrigerant circuit. The operation of these two refrigerant circuits is controlled by starting and stopping the fan of the outdoor heat exchanger. When the outdoor fan stops, the outdoor heat exchanger in the cooling circulation refrigerant circuit does not exchange heat, and all the refrigerant gas flows into the second hot water circulation refrigerant circuit, where the refrigerant condenses and releases heat to produce hot water in the hot water heat exchanger. The condensate then enters the indoor heat exchanger through the second throttle valve for cooling. When the outdoor fan is running, the outdoor heat exchanger releases heat and the indoor heat exchanger provides cooling. The operation and stop of the indoor fan and the circulation water pump, as well as the rotation and stop of the outdoor fan, are determined by comparing the hot water temperature Tw in the hot water tank and the indoor temperature Ta with the set values. Let Tw0 be the upper limit value of the set hot water temperature, which can be adjusted between 40 - 55°C. Let △Tw be the allowable water temperature fluctuation value for the set cooling, and usually, Tw0 = 50°C and △Tw = 5°C are default values. When Tw ≤ (Tw0 - △Tw) (the lower limit value of the set water temperature) and Ta < T0h (the set heating indoor temperature), the four-way valve is in the heating position, and the indoor fan and the circulation water pump stop to produce hot water with concentrated full heat. When Tw ≤ (Tw0 - △Tw) (the lower limit value of the set water temperature) and Ta > T0c (the set air-conditioning cooling indoor temperature), the four-way valve is in the cooling position, and the outdoor fan stops to produce hot water with concentrated full heat and also produce air-conditioning cold water. When Tw ≥ Tw0 (the upper limit value of the set water temperature) and Ta < T0h (the set heating indoor temperature), the indoor fan and the circulation water pump run for concentrated heat heating. When Tw ≥ Tw0 (the upper limit value of the set water temperature) and Ta > T0c (the set air-conditioning cooling indoor temperature), the outdoor fan runs for concentrated indoor cooling.

[0010] The described new type of three-in-one air-conditioning and hot water machine is characterized by having three basic modes: hot water production, cooling with hot water production, and heating with hot water production modes; and two additional modes (available in the advanced version): dehumidification with heat compensation and hot air humidification modes. The specific control programs for the five operating modes, the starting and stopping of the corresponding electrical components, the operating refrigerant circuits, and the combined heat and power system are as follows: (1) The hot water making mode is an independent hot water making mode in spring and autumn. The four-way valve is in the heating position (①③, ②④ are connected, and the coil is energized). The following is executed: the first hot water making circulation fluorine circuit, the compressor and the outdoor fan are running; after the user manually presses the button or specifies the "hot water making" mode by voice control, it enters automatic control: 1) The indoor fan and circulating water pump stop, the heating circulation fluorine circuit does not exchange heat, and the fluorine gas does not circulate; 2) The hot water circulation pump runs, the hot water circulation heating water circuit runs, and the corresponding integrated water tank hot water heat exchanger is used for hot water self-circulation heating; 3) The hot water outlet system discharges hot water at the top pressure; When Tw ≤ (Tw0 - △Tw) (1), the hot water mode is automatically started; When Tw ≥ Tw0 (2), the hot water mode stops automatically, the compressor, indoor and outdoor fans stop running; the four-way valve is still in the heating position (the coil potential remains unchanged); to exit the hot water mode, human intervention is used, that is, the "shutdown" button is touched; (2) Cooling and hot water mode is a cooling and hot water mode in summer. The four-way valve is in the cooling position (①②, ③④ are connected, and the coil is not powered), and the three-way valve is in the first and third interface connection position (hot water circulation heating path); Ta is the room temperature control parameter. The user can adjust and set the cooling room temperature Ta0c. The default Ta0c = 26℃. After the user manually presses the button or specifies the "cooling and hot water" mode by voice control, When Ta >Ta0c (3), the cooling and hot water mode is automatically started, and the second hot water circulation fluorine circuit of the two fluorine circuits is in operation; the hot water priority principle is implemented, and the operation of the refrigeration circulation fluorine circuit is controlled by the water temperature Tw of the hot water tank: When Tw ≤ (Tw0 - △Tw), the outdoor fan stops, the outdoor heat exchanger does not exchange heat, and the fluorine gas is retained in the refrigeration cycle fluorine circuit; the second hot water circulation fluorine circuit operates, and the hot water heat exchanger fully collects heat to produce hot water; the indoor heat exchanger absorbs heat for cooling, and the indoor fan of the fluorine-wind indoor heat exchanger turns to blow cold air; the circulating water pump runs, the fluorine-water-indoor heat exchanger produces chilled water, and the fan of the water-wind-fan coil heat exchanger runs to blow cold air; When Tw ≥ Tw0, or the outdoor fan delay reaches the set time (to simplify the control, the outdoor fan delay start control can also be adopted, usually 10-20 minutes), the outdoor fan starts, the refrigeration cycle fluorine circulates, the outdoor heat exchanger dissipates heat, and the indoor heat exchanger cools; the water temperature in the hot water tank will absorb the heat of the superheated gas of the high-pressure refrigerant, and the temperature can rise by more than 50℃, just let it be, without intervention; When Ta = Ta0 (4) Keep the compressor and indoor fan running at low speed; the circulating water pump and hot water circulating pump stop; When Ta < (Ta0 - △Tac) (5) and Tw ≥ Tw0, the compressor, indoor and outdoor fans, circulation pump, and hot water circulation pump stop running; the four-way valve remains in the cooling position; Note: △Tac is the allowable temperature fluctuation of the room temperature in the cooling mode, and it is recommended to default △Tac = 1°C; (3) The heating and hot water mode is the mode of heating and producing domestic hot water in winter. The four-way valve is in the heating position (①③ and ②④ are internally connected, and the coil is energized), and the three-way valve is in the position where the first and third interfaces are internally connected (the position of the domestic hot water circulation). The user can adjust and set the heating room temperature Ta0h, with the default Ta0h = 22°C; when the user manually presses the button or voices the command to specify the "heating and hot water" mode, When Ta < Ta0h (6), the heating and hot water mode starts to operate, and the first hot water circulation fluorine circuit automatically runs; the principle of giving priority to hot water production is implemented. When Tw ≤ (Tw0 - △Tw), the indoor fan and the circulation pump do not operate, the fluorine gas in the heating circulation fluorine circuit does not condense, and the fluorine gas flows concentratedly through the first hot water circulation fluorine circuit, and all the heat is collected in the hot water heat exchanger to produce domestic hot water. When Tw ≥ Tw0, the indoor fan and the circulation pump operate, the fluorine gas in the heating circulation fluorine circuit flows, and the indoor heat exchanger produces hot air and heating hot water; the water temperature in the hot water tank will exceed 50°C due to absorbing the heat of the superheated refrigerant gas, and there is no need to intervene naturally. When Ta = Ta0h, the compressor and the indoor fan maintain low-speed operation. When Ta > (Ta0h + △Ta0h) and when Tw ≥ Tw0, the compressor, indoor and outdoor fans stop running; the four-way valve remains in the heating position; △Ta0h is the allowable temperature for the room temperature to be too high, and the default △Ta0h = 1°C. (4) The dehumidification and heat compensation mode: It is only set for the advanced version models equipped with dehumidification and heat compensators and users in the areas south of the Yangtze River. It is the dehumidification and heat compensation mode when the room temperature is low and the humidity is high; Starting conditions: When the indoor relative humidity Φ≥ ≥ 65% and the room temperature is lower than 22°C, start the dehumidification mode to operate by manual intervention or automatically; Control: The four-way valve is in the cooling position (①② and ③④ are internally connected, and the coil is not energized), and the three-way valve is in the position where the second and third interfaces are internally connected (the position of the humidity adjustment and heat compensation circulation waterway operation); The compressor and the outdoor fan operate; The refrigeration circulation fluorine circuit operates, and the indoor fan operates at a low wind speed for dehumidification; Waterway operation: 1) The cooling / hot water circulation waterway, and the fan of the water-air heat exchanger operates at a low speed; The circulation pump operates, and the water-air - fan coil heat exchanger blows cold air for dehumidification; 2) The humidity adjustment and heat compensation circulation waterway operates, the three-way valve (②③ passage), and the hot water circulation pump operates, and the hot water generated by the hot water heat exchanger compensates heat to the dehumidification and heat compensator (hot air humidifier); When the indoor relative humidity Φ< ≤ 50%, stop dehumidification by manual intervention or automatically. (5) Hot air humidification mode: This mode is only available for advanced models equipped with hot air humidifiers and users in areas north of the Yellow River. It is used to adjust the indoor humidity during the winter heating period. Φ <40%, enabled when room temperature is ≥22℃; the system fluorine circuit still runs in heating mode, the four-way valve is in the heating position (①②, ③④ are connected, the coil is without electricity), but the three-way valve is in the second and third interface internal connection position (②③ passages), the humidity adjustment and heating circulation water circuit is running, and the humidification and water supply valve is opened; when Tw ≤ (Tw0 - △Tw), the three-way valve returns to the first and third interface internal connection position (②③ passages), the hot water circulation heating water circuit is running, and the humidification and water supply valve is automatically closed; or Φ> 50%, the humidification water supply valve is automatically closed. If Tw >Tw0, the three-way valve is in the connecting position between the second and third interfaces (②③ passages), and the hot air humidifier is used as a water-to-air fan coil heat exchanger to participate in heating the room.

[0011] The novel three-purpose cooling and heating air-conditioning water heater is provided with an automatic defrost cycle in the heating and hot water mode; the starting conditions of the defrost cycle are: when the outdoor temperature is lower than 5°C during the heating mode operation, the temperature difference between the outdoor air temperature and the tube wall temperature of the outdoor heat exchanger suddenly exceeds the set value, or the tube wall temperature of the outdoor heat exchanger suddenly drops rapidly, and the drop rate exceeds the normal drop rate by 1 times, and the control system issues a defrost command and enters the defrost mode operation; its characteristics are: the four-way valve is controlled to be in the cooling position, the fluorine circuit is the same as the refrigeration cycle fluorine circuit, the outdoor fan stops, and the indoor fan stops; when the model is equipped with a fluorine water-indoor heat exchanger, the cold / hot water circulation water circuit is running, the circulating water pump is running, and the hot water in the water supply tank supplies heat to the fluorine water-indoor heat exchanger of the indoor heat exchanger, which can be defrosted quickly.

[0012] The novel three-purpose cooling and heating air-conditioning water heater is characterized in that: the novel three-purpose cooling and heating air-conditioning water heater adopts a cold / hot water circulation zone coordinated cooling / heating mode, and arranges water-wind-fan coil heat exchangers in the living room, study, master bedroom, second bedroom, etc.; the water-wind-fan coil heat exchanger is a wall-mounted thin rectangular box with a forced convection heat exchanger with a wind wheel, the wind wheel can be stepped or DC variable speed, the inlet and outlet are equipped with temperature detection, which can be directly displayed, or transmitted to the host control panel by wire or wirelessly, and the wind wheel speed can be adjusted manually or remotely; the zone coordinated control mode is to adjust the indoor fan and the zoned water-wind-fan coil exchanger in association with the data detected by the room temperature and humidity sensors arranged in each area, the duration and needs of the human activity area. The fan speed of the water-to-air fan coil heat exchanger is used to adjust the cooling / heating time and intensity of each area, and the cooling or heating amount is allocated by adjusting the fan speed of each water-to-air fan coil heat exchanger; the advanced version of the zone coordination control method is to gradually compile the cooling / heating needs of each area through theoretical modeling and artificial intelligence, and customize the intensity of cooling and heating, fan speed, and operating time for automatic control; the zone coordination control method is people-oriented and serves people. It distributes cooling or heat according to the different weights of the needs of each area, and allocates limited cooling and heat to where they are most needed. It is the core foundation of intelligent control, which not only improves comfort but also saves energy. The cooling / heating amount prepared by smaller-power refrigeration equipment can meet the cooling and heating needs of rooms with larger areas.

[0013] The novel three-purpose cooling and heating air-conditioning water heater is characterized in that: the hot air humidifier is formed by adding a wet mesh cloth, a water supply pipe, a hot water discharge pipe for heating the wet cloth, and a water storage tank to the air duct of the water-air-fan coil heat exchanger; the principle of the hot air humidifier is to use the added hot water discharge pipe to heat the wet cloth when the water-air-fan coil heat exchanger is used for heating, and to use the hot air to blow through the wet mesh or wet cloth to bring water vapor into the room; the water supply pipe, the hot water discharge pipe for heating the wet cloth, and the inlet and outlet pipes of the hot water-air heat exchanger discharge pipe bundle are connected in parallel; a water supply fine-tuning valve is installed on the water inlet pipe of the water supply pipe, and the water supply pipe is connected to the room; the hot ... There are many tiny water seepage holes on the tube, and the seepage water drips to moisten the humidification cloth or humidification net; the hot air humidifier is equipped with inlet and outlet temperature detectors at the inlet and outlet, and a humidity detector is installed at the inlet; a touch screen control display is installed at one end of the top surface of the thin rectangular box of the hot air humidifier, which normally displays the temperature and humidity of the incoming air, the operation mode, and the fan speed gear; the overflow pipe of the water storage tank is connected to the drain pipe behind the bottom drain valve, and the drain pipe is connected to the outdoors; the water level gauge of the water storage tank is visible; the hot air humidifier is only used to provide indoor heating in winter, and the water replenishment fine-tuning valve is closed at other times.

[0014] The innovative features of the present invention mainly include: 1. One of the innovative highlights of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is the structural innovation of adding a hot water heat exchanger and its fluorine circuit connection: a hot water heat exchanger is added to the fluorine circuit system of the traditional cooling and heating air-conditioning machine, and the air inlet of the fluorine circuit is designed with four connection modes to ensure that it is always in the position of the condenser with the same pressure as the compressor exhaust communication in the fluorine circuit, thereby creating four new three-purpose machines; the core is: the liquid outlet of the hot water heat exchanger is connected to the second interface (liquid outlet) of the outdoor and indoor heat exchangers through the two first and second throttles respectively; this innovative structure can form four fluorine circuit cycles with three functions distributed in the heating position and cooling position of the four-way valve with only one four-way valve; The core of the present invention is the two-throttle connection method of the bottom outlet of the hot water heat exchanger, which breaks through the double four-way valve structure of the "cold and warm air conditioning and hot water three-in-one machine". Only one four-way valve can cleverly form four fluorine circuit cycles with three functions, and hot water can be generated regardless of whether the three-in-one machine runs a refrigeration / heating cycle; the principle of the invention is: the condensate of the hot water heat exchanger passes through the two-way throttle, and with the help of the pressure difference between the compressor exhaust pressure and the indoor or outdoor heat exchanger used as an evaporator, the throttling path is automatically selected, so the control is greatly simplified and the operating stability is greatly increased; the present invention does not need fluorine circuit valve control, and the refrigerant can automatically condense in the hot water heat exchanger to make hot water, or in the indoor Or the outdoor heat exchanger does not exchange heat and condenses; the deep-seated principle is: when the fan of the heat exchanger connected to the hot water heat exchanger does not rotate, there is no heat exchange, and the gas pressures of the two are equal, and the fluorine gas in the cooled heat exchanger condenses into liquid, the volume is reduced by hundreds of times, and the pressure is greatly reduced, so the refrigerant will continuously flow through the hot water heat exchanger with a cooling source; in the heat exchanger where the fan stops and there is no cold water heat exchange, the fluorine gas pressure cannot be reduced, and the fluorine gas cannot flow into the throttle; the throttle is a passage for liquids and a blocker for gases; the above three innovations have made the three-purpose machine with four cycles of cooling, heating and dual-source hot water production extremely simple, with obvious novelty and outstanding advancement, and are original inventions.

[0015] 2. The second innovative highlight of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is the key component of the second novel three-purpose machine, i.e., the front-mounted three-purpose machine, the gas-liquid separation cylinder, which is composed of a Y-shaped three-way joint and three sections of pipelines, and is vertically installed with the liquid outlet at the bottom, and the two interfaces of the liquid / gas inlet and the gas outlet are distributed on the two upper pipes of the Y-shaped three-way joint. Practice has proved that the Y-shaped three-way joint is used to make a gas-liquid separator, which is easy to make, has a good gas-liquid separation effect, has low resistance, and can be mass-produced.

[0016] 3. The third innovative highlight of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is the third novel three-purpose machine, i.e., the rear-mounted three-purpose machine. A one-way valve is added to the second interface of the outdoor heat exchanger and the indoor heat exchanger, and the outlets of the two one-way valves are connected to the air inlet of the hot water heat exchanger. This ensures that only the refrigerant in the high-pressure circuit can enter the hot water heat exchanger, whether it is a cooling or heating cycle, and the hot water heat exchanger always acts as a supercooling heat exchanger after the indoor or outdoor heat exchanger of the condenser, absorbing the supercooling sensible heat of the refrigerant liquid, thereby increasing the refrigeration efficiency during refrigeration. The two one-way valves added to the fluorine circuit are the key technology and invention point of the rear-mounted three-purpose machine, which saves the two-way throttle between the indoor and outdoor heat exchangers and has a lower cost.

[0017] 4. The fourth innovative highlight of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is the fourth novel three-purpose machine, i.e., a semi-parallel and semi-rear-mounted three-purpose machine, in which the second one-way valve is directly connected to the inlet of the hot water heat exchanger from the third interface of the four-way valve, and together with the indoor heat exchanger connected to the third interface of the four-way valve, forms a parallel form of two heat exchangers; the hot water heat exchanger and the indoor heat exchanger each have a throttle (the first and third throttles) connected to the second interface of the outdoor heat exchanger; in this way, the hot water heat exchanger is used as a subcooling heat exchanger in the refrigeration cycle to improve the refrigeration efficiency; in the heating cycle, the heat can be more concentrated on the indoor heat exchanger for heating.

[0018] 5. The fifth innovative highlight of the novel three-purpose cooling and heating air-conditioning and water-heating machine described in the present invention is the innovation of fluorine circuit circulation control. The novel three-purpose cooling and heating air-conditioning and water-heating machine described in the present invention controls four circulating fluorine circuits by changing the position of a four-way valve and starting and stopping the fans and circulating water pumps associated with the indoor and outdoor heat exchangers. Its control method overturns the traditional thinking of adding a control valve to the fluorine circuit to rigidly change the control mode of the fluorine circuit flow path. It solves the problems of air and liquid leakage at the high and low pressure ends of the valve and the problem of ineffective valve switching when adding a control valve to the fluorine circuit, and is an original breakthrough innovation in the control method of the three-purpose cooling, heating, and water-heating machine. Advantages: It simplifies the structure of the fluorine circuit system and ensures stable and reliable system operation. The cleverness lies in that the first and second hot water circulating fluorine circuits of the fluorine circuit do not need to be controlled by valves, and the refrigerant will find the path by itself to run. In addition, a hierarchical control principle and method with hot water priority is proposed to control the start and stop of the fan and circulating water pump.

[0019] 6. The novel three-purpose cooling and heating air-conditioning water heater described in the present invention has the sixth innovative highlight, which is the design of the fluorine wind-fluorine water-indoor heat exchanger connected in series with the indoor heat exchanger of the triple system; the key point of the outdoor unit fluorine wind-indoor heat exchanger and the fluorine water-indoor heat exchanger connected in series is: due to the different volumes of the two heat exchangers, the connection sequence is incorrect, and fluorine deficiency will occur during operation; the present invention correctly selects which one is installed in the indoor fluorine wind-indoor heat exchanger port to connect the four-way valve, and the installation is consistent with the indoor fluorine wind-indoor heat exchanger. The outdoor fluorine-water-indoor heat exchanger is connected to the throttle end; the reason is: when operating in heating mode, the fluorine-wind-indoor heat exchanger is at the front section of the airflow, and the condensate after condensation passes through the fluorine-water-indoor heat exchanger with a small volume, so there will be no fluorine deficiency, and it also serves as a subcooler; when cooling, the fluorine-water-indoor heat exchanger first receives the throttled liquid refrigerant, evaporates, and the fluorine moisture passes through the fluorine-wind-indoor heat exchanger, so there will be no fluorine deficiency, and it also serves as a superheater, which increases the enthalpy value of the fluorine gas entering the compressor and saves compression work.

[0020] 7. The seventh innovative highlight of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention lies in the design of the hot water heat exchanger and the domestic hot water heating system: (1) When an integrated water tank hot water heat exchanger is used, the innovative point is: a stop valve with a fluorine circuit inlet and outlet interface is installed on the hot water tank shell, and one of the stop valves has a fluorine filling interface, which is convenient for the separate installation of the hot water tank for fluorine injection; (2) When the hot water heat exchanger uses a high-efficiency tank or a plate heat exchanger, it is directly installed in the outdoor machine body, and the fluorine circuit is connected by welding to form an integrated three-purpose machine; if it is equipped with a pressurized hot water tank, the top pressure hot water outlet method is adopted; (3) If a non-pressurized hot water tank is selected, a domestic hot water heat exchange coil is placed in the hot water tank, and the domestic hot water heat exchange coil bears the tap water pressure. In high-rise buildings with high water supply pressure, it is very beneficial to avoid pressurized water tank accidents.

[0021] 8. The eighth innovative highlight of the new three-purpose cold and hot air conditioning water heater described in the present invention is that a gas-liquid separation type water supply tank is added to the cold / hot circulating water water exchange water circuit of the trigeneration system. The bottom water outlet is connected to the inlet of the circulating water pump, and there is an air release valve on the top of the water supply tank. This point is extremely important and is the key to ensuring that the circulating water pump can deliver water normally without bubbles.

[0022] 9. The new three-purpose cooling and heating air-conditioning water heater described in the present invention has the ninth innovative highlight. In the trigeneration system of the advanced version, a humidity regulating and heating circulation water circuit consisting of a hot water heat exchanger, a dehumidification and heating device (also a hot air humidifier) ​​and a hot water circulation pump is added. When the temperature is low in the spring and the refrigeration and dehumidification cycle is in progress, the dehumidification and heating device is used to heat the room; when the room is too dry during heating in winter, the hot air humidifier is used to humidify the room; the hot air humidifier is connected to the humidity regulating and heating circulation water circuit, and when the valve of the water supply pipe is not opened, it is used as a radiator. When the temperature is low and the dehumidification is carried out, heat can be supplied to the room to offset the heat loss in the room during dehumidification; in winter, when the indoor humidity is too low during the winter heating period in the dry northern regions, the room can be humidified, so that one device can serve three purposes.

[0023] 10. The novel three-purpose cooling and heating air-conditioning water heater of the present invention has the tenth innovative highlight. The present invention proposes an innovative hardware configuration and control idea for air-conditioning heat exchanger for energy-saving use of reasonable cooling / heating distribution in rooms. It adopts a fluorine-wind-fluorine-water indoor heat exchanger in which a fluorine-wind-indoor heat exchanger and a fluorine-water-indoor heat exchanger are connected in series, and cooperates with the water-wind-fan coil heat exchanger installed in each room to form a cold / hot water circulation water exchange circuit, which is distributed to the living room and each room as needed, making up for the shortcoming that fluorine-wind cooling / heating cannot extend the space, extending the use space of cold / heating, shifting the peak supply, and being comfortable and energy-saving. It is the prototype of AI intelligent control mode; in addition, the control adopts the principle of hot water making priority, and realizes the internal circulation switching of cooling / heating and hot water making in cooling and hot water making mode and heating and hot water making mode.

[0024] 11. The novel three-purpose cooling and heating air-conditioning water heater described in the present invention has the eleventh innovative highlight that there is a heat source for defrosting. In a system equipped with a fluorine water-indoor heat exchanger, the defrosting problem of the cooling and heating air-conditioning machine is completely solved.

[0025] 12. The most outstanding advantage of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is that it has obvious energy-saving effect. In summer, it can perform cooling and hot water production at the same time. The obtained hot water is completely free and can improve the cooling efficiency. The energy efficiency ratio in summer exceeds 8; in spring and autumn, it absorbs heat from the outdoor to make hot water, which saves 70-75% of electricity compared with electric water heaters; multi-mode energy-saving operation, the defrosting mode in winter is good and energy-saving; the annual average COP of the unit for hot water production is greater than 5.5, and the system structure is simple, easy to control, and the unstable factors in operation are greatly resolved; in summary, the novel three-purpose cooling and heating air-conditioning water heater described in the present invention has a clear structural novelty, breakthrough originality, solid theoretical basis for innovation, many technical innovations, remarkable energy-saving effect, outstanding advancement, and obvious practicality, which meets the three requirements of invention patents.

Ta is the room temperature control parameter. The user can adjust and set the cooling room temperature Ta0c. The default Ta0c = 26℃. After the user manually presses the button or specifies the "cooling and hot water" mode by voice control, When Ta >Ta0c (3) Automatically start the cooling and hot water mode, the second hot water circulation fluorine circuit of the two fluorine circuits is running; the hot water priority principle is implemented, and the operation of the refrigeration circulation fluorine circuit is controlled by the water temperature Tw of the hot water tank: When Tw ≤ (Tw0 - △Tw), the outdoor fan stops, the outdoor heat exchanger does not exchange heat, and the fluorine gas is retained in the refrigeration cycle fluorine circuit; the second hot water circulation fluorine circuit operates, and the hot water heat exchanger fully collects heat to produce hot water; the indoor heat exchanger absorbs heat for cooling, and the indoor fan of the fluorine-wind indoor heat exchanger turns to blow cold air; the circulating water pump runs, the fluorine-water-indoor heat exchanger produces chilled water, and the fan of the water-wind-fan coil heat exchanger runs to blow cold air; When Tw ≥ Tw0, or the outdoor fan delay reaches the set time (to simplify the control, the outdoor fan delay start control can also be adopted, usually 10-20 minutes), the outdoor fan starts, the refrigeration cycle fluorine circuit fluorine flows, the outdoor heat exchanger dissipates heat, and the indoor heat exchanger cools; The water temperature in the hot water tank will rise by more than 50°C due to the absorption of heat from the superheated gas of the high-pressure refrigerant. Just let it happen naturally without intervention. When Ta = Ta0 (4) Keep the compressor and indoor fan running at low speed; the circulating water pump and hot water circulating pump stop; When Ta < (Ta0-△Tac) (5), and Tw ≥Tw0, the compressor, indoor and outdoor fans, circulating water pump, and hot water circulating pump stop running; the four-way valve maintains the cooling position; Note: △Tac is the room temperature that is allowed to fluctuate in cooling mode.

It is used to adjust the indoor humidity during the winter heating period. Φ <40%, it is enabled when the room temperature is ≥22℃; the system fluorine circuit still runs in heating mode, the four-way valve is in the heating position (①②, ③④ are connected, and the coil is without electricity), but the three-way valve is in the connecting position between the second and third interfaces (②③ passages), the humidity control and heating circulation water circuit is running, and the humidification and water supply valve is opened; when Tw ≤ (Tw0 - △Tw), the three-way valve returns to the connecting position between the first and third interfaces (①③ passages), the hot water circulation heating water circuit is running, and the humidification and water supply valve is automatically closed; or when Φ>50%, the humidification and water supply valve is automatically closed; if Tw >Tw0, the three-way valve is in the connecting position between the second and third interfaces (②③ passages), and the hot air humidifier is used as a water-air-fan coil heat exchanger to participate in heating the room.
