Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning water heaters, in particular to a throttle valve for an air-conditioning water heater and an air-conditioning water heater. Background Art

[0002] For decades, many companies have been developing air conditioning waste heat recovery and utilization, especially from 2000 to 2005, many manufacturers developed air conditioning water heaters with air conditioning waste heat recovery function. However, the failure and maintenance rate of air conditioning water heaters is too high, and they cannot adapt to market use, so they have to give up. After decades of research, the main reasons why air conditioning waste heat recovery products have not been introduced to the market are as follows:

[0003] 1. In the air-conditioning water heater system, a four-way valve is usually used. The four-way valve structure includes nylon parts and capillaries. Frequent startup and rapid wear during operation lead to poor sealing and air leakage, shortening the life of the four-way valve and causing malfunctions in the air-conditioning water heater system.

[0004] 2. The coil in the solenoid valve structure generates heat when working. After working for a long time, the heat accumulates. When the temperature is high, the solenoid valve will malfunction, affecting the normal operation of the air conditioning water heater system.

[0005] 3. In the pipelines of the air-conditioning water heater system, in addition to the four-way valve, there are also multiple solenoid valves. When in use, the solenoid valves are frequently switched on and off, and the failure rate will also increase.

[0006] For the reasons mentioned above, the maintenance rate of air-conditioning water heater system products is too high, which causes the factory to lose money or even go bankrupt. Therefore, air-conditioning water heater system products have not been able to enter the market. Utility Model Content

[0008] The throttle valve of the air conditioner water heater is characterized in that two parallel pipelines are arranged in the valve body, the first parallel pipeline includes a first pipeline and a second pipeline, the first capillary tube and the valve A are connected in the first pipeline, and the valve B is connected in the second pipeline;

[0009] The second parallel pipeline includes a third pipeline and a fourth pipeline; a valve C is arranged in the third pipeline; and a valve D and a second capillary are connected in the fourth pipeline.

[0010] Preferably, the valve A and valve D are solenoid valves.

[0011] Preferably, the valve B and valve C are one-way valves.

[0012] Preferably, in the throttle valve of the air-conditioning water heater, a filter is connected before the first parallel pipeline; in the third pipeline, a filter is connected after the valve C.

[0013] The air-conditioning water heater based on the air-conditioning water heater throttle valve is characterized by comprising a compressor, an evaporator, an air conditioner, and a water tank;

[0014] A four-way valve is connected to the compressor pipeline, one of the interfaces of the four-way valve is connected to the evaporator, and the evaporator is connected to the first parallel pipeline; the second parallel pipeline is connected to the air conditioner and the water tank respectively, wherein the third pipeline is connected to the water tank, and the water tank is connected to one of the interfaces of the four-way valve; the fourth pipeline is connected to the air conditioner, and then the air conditioner is connected to the compressor;

[0015] The third interface of the four-way valve is connected with a fifth pipeline, and the fifth pipeline is connected to the pipeline connecting the air conditioner and the compressor.

[0016] Preferably, the air-conditioning water heater based on the air-conditioning water heater throttle valve is divided into a household working connection state and a commercial working connection state;

[0017] The four-way valve interfaces are respectively the first interface, the second interface, the third interface, and the fourth interface; the first interface is connected to the compressor, and the third interface is connected to the liquid storage tank to the compressor;

[0018] In the home working connection state: the evaporator is connected to the fourth interface, and the water tank is connected to the second interface;

[0019] In the commercial working connection state: the evaporator is connected to the second interface, and the water tank is connected to the fourth interface.

[0020] Preferably, the air-conditioning water heater based on the throttle valve of the air-conditioning water heater is provided with a normally open solenoid valve and a normally closed solenoid valve.

[0021] Beneficial effects of the utility model:

[0022] The throttle valve and the air-conditioning water heater provided by the utility model are an air-conditioning water heater system that is more energy-efficient than using solar energy, and are achieved by installing the throttle valve and pipeline design provided by the utility model at the end of the air-conditioning water heater compressor pipeline.

[0023] The energy-saving air-conditioning water heater system of the present invention has at least three operating modes, namely, the single air-conditioning cooling mode; the second is the air-conditioning cooling and hot water making mode; and the third is the single hot water making mode. Combined with the throttle valve and pipeline design in the present invention, energy saving and higher efficiency can be achieved. In addition, in the air-conditioning cooling and hot water making mode, heat recovery is carried out and the air-conditioning outdoor unit does not run, thereby saving more electricity, achieving the effect of energy saving when using air conditioning and providing free hot water.

[0024] The energy-saving air-conditioning water heater system of the utility model can be used as a household machine: less hot water is used, the hot water making time is short, and more electricity is saved. It can be used as a commercial machine: based on the household machine, it can be realized by exchanging the position of the pipe connection in the four-way valve. The commercial machine takes a long time to make hot water, and the four-way valve and the household machine have different connection states, which reduces the working time of the coil and increases the life. In the utility model, the four-way valve does not need to be frequently switched, and the solenoid valve is set with normally open and normally closed, and is not frequently started, so as to avoid the solenoid valve and the four-way valve from being burned out by high temperature. In combination with the pipeline design of the energy-saving air-conditioning water heater system, more use of solenoid valves is avoided and one-way valves are used in the system. The one-way valve does not need to be energized, is not easily damaged, and works more reliably, making the operation of the entire energy-saving air-conditioning water heater system more reliable.

[0039] The second parallel management includes a third pipeline and a fourth pipeline; a valve C4 is provided in the third pipeline; and a valve D5 and a second capillary tube 6 are connected in the fourth pipeline.

[0041] The throttle valve provided in Example 1 is installed at the end of the pipeline of the air-conditioning water heater compressor 8, and combined with the pipeline design of the energy-saving air-conditioning water heater system, fewer electronic valves can be used, thereby reducing the system failure rate.

[0043] Based on the structure of Example 1, in the throttle valve of the air-conditioning water heater, a filter 7 is connected before the first parallel pipeline; in the third pipeline, a filter 7 is connected after the valve C4.

[0044] The connection of the filter 7 can filter impurities in the water, thereby reducing scale and extending the service life.

[0045] Example 3

[0046] Based on the structure of embodiment 1, the air-conditioning water heater based on the air-conditioning water heater throttle valve is characterized in that it includes a compressor 8, an evaporator 9, an air conditioner 10, and a water tank 11;

[0047] In this embodiment, a four-way valve 12, a normally open solenoid valve, a normally closed solenoid valve, two throttle valves or two capillaries are arranged in the working system.

[0048] A four-way valve 12 is connected to the pipeline from the compressor 8, one of the interfaces of the four-way valve 12 is connected to the evaporator 9, and the evaporator 9 is connected to the first parallel pipeline; the second parallel pipeline is connected to the air conditioner 10 and the water tank 11 respectively, wherein the third pipeline is connected to the water tank 11, and the water tank 11 is connected to one of the interfaces of the four-way valve 12; the fourth pipeline is connected to the air conditioner 10, and then the air conditioner 10 is connected to the compressor 8;

[0049] The third interface of the four-way valve 12 is connected to a fifth pipeline, and the fifth pipeline is connected to the pipeline connecting the air conditioner 10 and the compressor 8 .

[0050] Valve A2 and valve D5 are solenoid valves; valve B3 and valve C4 are one-way valves.

[0051] The air-conditioning water heater provided by the utility model is divided into a household working connection state and a commercial working connection state;

[0052] The interfaces of the four-way valve 12 are respectively a first interface 13, a second interface 14, a third interface 15, and a fourth interface 16; the first interface 13 is connected to the compressor 8, and the third interface 15 is connected to the liquid storage tank to the compressor 8;

[0053] In the home working connection state: the evaporator 9 is connected to the fourth interface 16, and the water tank 11 is connected to the second interface 14;

[0054] In the commercial working connection state: the evaporator 9 is connected to the second interface 14 , and the water tank 11 is connected to the fourth interface 16 .

[0055] The air-conditioning water heater provided by the utility model has the following four working modes in the home working connection state:

[0056] 1. Single air conditioning cooling mode:

[0057] In the home working connection state (household machine), the air conditioning cooling period is long, and the hot water making period is very short, so the single air conditioning cooling mode and the single hot water making mode are designed, which is more convenient for customers to use and can achieve the best energy-saving effect.

[0058] Valve D5 is a normally open solenoid valve, and valve A2 is a normally closed solenoid valve. When used at home, the four-way valve 12 is not energized, valve A2 is closed, and the high-temperature hot air is directly discharged to the evaporator 9. The compressor 8 is connected to the four-way valve 12, and the four-way valve 12 is connected to the evaporator 9. The refrigerant then passes through valve B3, valve D5 and the second capillary tube 6, is cooled by the air conditioner 10, and returns to the compressor 8.

[0059] When used as a household machine, in the single air conditioning cooling mode, the four-way valve 12, valve A2, and valve D5 are all used in the non-powered state.

[0060] 2. Air conditioning cooling and hot water production mode:

[0061] Valve D5 is a normally open solenoid valve, and valve A2 is a normally closed solenoid valve; valve A2 is closed, and the compressor 8 is connected to the four-way valve 12. When used at home, the four-way valve 12 is energized, and the four-way valve 12 is connected to the water tank 11. The water tank 11 is connected to valve C4, valve D5, and the second capillary tube 6, and then cooled by the air conditioner 10 and returned to the compressor 8.

[0062] When the machine is used at home, in the air-conditioning cooling and hot water making mode, the four-way valve 12 is in the energized working state; the valve A2 and the valve D5 are used in the non-energized state.

[0063] 3. Hot water only mode:

[0064] When the room does not need cooling but the water tank 11 needs heating, it operates in a hot water only mode. Valve D5 is a normally open solenoid valve, and valve A2 is a normally closed solenoid valve; valve D5 is closed, and the compressor 8 is connected to the four-way valve 12. When used at home, the four-way valve 12 is energized, and the four-way valve 12 is connected to the water tank 11. The water tank 11 is connected to valve C4 and valve A2, and then connected to the evaporator 9 after passing through the first capillary tube 1. The evaporator 9 is connected to the four-way valve 12 and then returns to the compressor 8.

[0065] In the case of a household machine, in the hot water only mode, the four-way valve 12, valve A2, and valve D5 are used in the energized state.

[0066] In the home working connection state, the air conditioner is used for cooling for a long time and the hot water is used for a short time. The second interface 14 is normally closed and the fourth interface 16 is normally open. During cooling, the four-way valve 12 is not powered and the coil does not heat up. When hot water is used, the four-way valve 12 is powered for a shorter time, so no heat is accumulated.

[0067] 4. Heating air mode:

[0068] The electric auxiliary heating of the air conditioner indoor unit is used alone to realize the hot air blowing function.

[0069] The air-conditioning water heater provided by the utility model has the following three working modes in the commercial working connection state:

[0070] 1. Single air conditioning cooling mode:

[0071] Valve D5 is a normally open solenoid valve, and valve A2 is a normally closed solenoid valve. When used commercially, the four-way valve 12 is energized, valve A2 is closed, and the high-temperature hot air is discharged directly to the evaporator 9. The compressor is connected to the four-way valve 12, and the four-way valve 12 is connected to the evaporator 9. The refrigerant then passes through valve B3, valve D5 and the second capillary tube 6, is cooled by the air conditioner 10, and returns to the compressor.

[0072] In the commercial machine, in the single air conditioning cooling mode, the four-way valve 12 is in the energized working state; the valves A2 and D5 are all used in the non-energized state.

[0073] 2. Air conditioning cooling and hot water production mode:

[0074] Valve D5 is a normally open solenoid valve, and valve A2 is a normally closed solenoid valve; valve A2 is closed, and the compressor is connected to the four-way valve 12. When in commercial use, the four-way valve 12 is in a non-powered state. The four-way valve 12 is connected to the water tank 11, and the water tank 11 is connected to valve C4, valve D5, and the second capillary tube 6, and then cooled by the air conditioner 10 and returned to the compressor 8.

[0075] In the commercial machine, in the air conditioning cooling and hot water making mode, the four-way valve 12, valve A2, and valve D5 are all used in the non-powered state.

[0076] 3. Hot water only mode:

[0077] When the room does not need cooling but the water tank 11 needs heating, it operates in a hot water only mode. Valve D5 is a normally open solenoid valve, and valve A2 is a normally closed solenoid valve; valve D5 is closed, and the compressor 8 is connected to the four-way valve 12. When in commercial use, the four-way valve 12 is not powered, and the four-way valve 12 is connected to the water tank 11. The water tank 11 is connected to valve C4 and valve A2, and then connected to the evaporator 9 after passing through the first capillary tube 1. The evaporator 9 is connected to the four-way valve 12 and then returns to the compressor 8.

[0078] In the commercial machine, in the hot water only mode, the four-way valve 12 is in a non-energized working state; the valve A2 and the valve D5 are used in the energized state.

[0079] In the commercial working connection state, the air conditioning refrigeration and hot water consumption are both large, such as the Middle East, Southeast Asia, South Africa and other hot areas, where air conditioning is needed all year round; for example, hotels, guesthouses, restaurants, barber shops, bath centers, foot massage shops and other places that use a lot of hot water; and in other cases where the amount of cold air and hot water is large, the second interface 14 is normally open, and the fourth interface 16 is normally closed. In the air conditioning refrigeration and hot water making mode, the four-way valve 12 is not energized, and the coil does not heat up, effectively avoiding damage to the four-way valve 12 and ensuring the stable operation of the air conditioning water heater system. The longer the air conditioning refrigeration and hot water making mode is used, the more heat is recovered from the air conditioning exhaust waste heat, the more hot water is used and made, the more electricity is saved, and the energy-saving effect is more reflected.

[0080] In the commercial working connection state (commercial machine), the air conditioner is in the cooling and hot water making mode: the four-way valve 12 is not powered, the compressor 8 enters the water tank 11 at high temperature for heat exchange, passes through the one-way valve C4, the normally open solenoid valve D5 (the coil of the valve D5 is not powered), and then enters the air conditioner 10 for cooling after throttling through the second capillary 6, and returns to the compressor 8. The normally closed solenoid valve A2 is also not powered, so when the air conditioner 10 is in the cooling and hot water making mode, the four-way valve 12, the normally closed solenoid valve A2, and the normally open solenoid valve 5 are not powered, and the coil will not heat up, so the probability of failure of the entire system is extremely low.

[0081] Compared with the solar water heaters in the prior art, when there is not enough sunlight or when hot water is needed at night, the solar water heater can only use electric heating to make hot water, while the air-conditioning water heater in the utility model can heat at any time, or recycle the heat discharged by the air conditioner or use heat pump to heat and make hot water; so it is more energy-saving than the solar water heater. Commercial machines are generally used in public places, and air conditioning refrigeration can also be made into central air conditioning.
