Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning refrigerator and heat pump heating, in particular to a water heater with both refrigerator and air-conditioning functions. Background Art

[0002] Refrigerators, air conditioners and electric water heaters are essential household appliances. The working principle of air conditioners and refrigerators is heat pump technology, which uses compressors to drive the circulation and phase change process of refrigerants to carry out heat transfer and conversion. The circulation of refrigerants is roughly divided into four processes: compression and heating process, gas-liquid phase change heat release process, throttling diffusion process and liquid-gas phase change heat absorption process; refrigerators transfer heat from low-temperature objects to high-temperature objects, and the gas-liquid phase change heat release process is concentrated in the outer shell of the refrigerator; air conditioners transfer heat from indoors to outdoors, and the gas-liquid phase change heat release process is outdoors. The working principle of electric water heaters is to use electric heating tubes to convert electrical energy into thermal energy. The electric heating tubes have high power and electric power efficiency less than 1. The water temperature is automatically controlled by the thermostat to achieve heating and insulation of water in a closed container. Another obvious defect of electric water heaters is that the electric heating tubes are in direct contact with hot water for bathing, which poses a risk of leakage. Initially, the inventor combined the refrigerator with the electric water heater, as detailed in Chinese invention patent 202411784191.5, and used the condensation heat release of the refrigerant gas phase change liquid to replace the electric heating tube of the water heater, and used the waste heat generated by the refrigerator to produce hot water; the experiment found that the hot water produced by the waste heat of the refrigerator was difficult to meet the sufficient and rapid supply of hot water for bathing, so the air conditioner was added. The condensation heat release of the air conditioner is concentrated inside the water heater, and the indoor unit of the air conditioner absorbs the indoor heat; similarly, the condensation heat release of the refrigerator is concentrated inside the water heater, and the internal freezer and refrigerator use the refrigerant evaporation heat absorption and cooling function. The working characteristics of the refrigerator are continuous, while the working characteristics of the air conditioner and water heater are sudden and large in quantity. The design is mainly based on the water heater, taking into account the functions of the air conditioner and the refrigerator. It achieves three goals in one fell swoop, not only using the waste heat discharged from the refrigerator and the air conditioner to produce a large amount of hot water, but also eliminating the risk of leakage of the water heater.

[0011] An introduction to the working principle of a water heater with both refrigerator and air conditioning functions A water heater with both refrigerator and air-conditioning functions, the water heater with both refrigerator and air-conditioning functions comprises an MCU microprocessor control circuit, a heat-dissipating refrigerator, an air-conditioning indoor unit and a water storage water heater, the heat-dissipating refrigerator is installed on a bottom plate against a wall in a restaurant, the MCU microprocessor control circuit and the water storage water heater are installed inside the heat-dissipating refrigerator, and the air-conditioning indoor unit is installed on a wall above the heat-dissipating refrigerator; the MCU microprocessor control circuit, the heat-dissipating refrigerator, the air-conditioning indoor unit and the water storage water heater are connected to each other via pipes or circuits; the MCU microprocessor control circuit manages all operations of the water heater with both refrigerator and air-conditioning functions.

[0012] The design idea of ​​the present invention is as follows: water storage water heaters and air conditioners are large electricity users. The water heater function is a rigid demand, with large quantities and concentrated time. The design takes the water storage water heater function as the main business, and the air conditioner and refrigerator as the auxiliary business; considering that the refrigerator does not consume much electricity, the auxiliary business supplements the main business. During the day, the water consumption of washing vegetables with hot water is small, and the hot water heated by the refrigerator is sufficient; when taking a bath at night, the hot water consumption is large, and the hot water stored during the day is not enough. After turning on the air conditioner, the heat release can be increased rapidly to produce more hot water to meet the needs of taking a bath. The water storage water heater is the heat load of the air conditioner. The water storage water heater must be filled with water before the water heater with both refrigerator and air conditioner functions can be used.

[0013] First, fill the storage water heater with water; first turn on the hot water outlet pipe switch, then turn on the tap water inlet pipe switch, until the tap water fills the water storage tank and the tap water flows out from the hot water outlet pipe, then turn off the hot water outlet pipe switch, and keep the tap water inlet pipe switch turned on; connect the power supply of the water heater with both refrigerator and air conditioner functions; the MCU microprocessor control circuit starts to work, monitors the internal water temperature A and water temperature B of the storage water heater, the temperature of the refrigerator and the temperature of the freezer, controls the three-position three-way solenoid valve to cool the freezer and the refrigerator, and the display shows the upper and lower water temperatures inside the storage water heater, the temperature of the refrigerator and the temperature of the freezer; initially, the upper and lower water temperatures inside the storage water heater, that is, water temperature A and water temperature B are the same.

[0014] The MCU microprocessor control circuit starts the compressor; the compressor inhales low-temperature and low-pressure refrigerant gas and pumps out high-temperature and high-pressure refrigerant gas, which passes through the insulated thick tube and enters the condenser network in the water tank; the high-temperature and high-pressure refrigerant gas changes phase and releases heat in the condenser network, and the condenser network heats the water storage water heater and fills it with water; the hot water has a light specific gravity and automatically floats up; at this time, the water temperature A begins to rise, and the water temperature B remains unchanged; the high-temperature and high-pressure refrigerant gas at the back pushes the medium-temperature and medium-pressure refrigerant liquid at the front forward to the three-position three-way solenoid valve position.

[0015] The MCU microprocessor control circuit opens the three-position three-way solenoid valve outlet 1, and the medium-temperature medium-pressure refrigerant liquid flowing out of the condenser pipe network passes through the insulation capillary, the three-position three-way solenoid valve outlet 1, and the expansion valve A; it comes out of the expansion valve A and enters the evaporation pipe network A, and the pressure drops suddenly. The medium-temperature medium-pressure refrigerant liquid absorbs heat in the evaporation pipe network A and changes into a low-temperature and low-pressure refrigerant gas. The temperature of the freezer around the evaporation pipe network A drops suddenly; the fan starts, and the temperature of each part of the freezer tends to be the same. When the temperature of the freezer drops to the set temperature, that is, the temperature sensor A detects that the temperature of the freezer drops to the set temperature, the MCU microprocessor control circuit closes the three-position three-way solenoid valve outlet 1, and the temperature of the freezer is maintained around the set temperature.

[0016] The MCU microprocessor control circuit opens the three-position three-way solenoid valve, and the medium-temperature and medium-pressure refrigerant liquid flowing out of the condenser pipe network enters the evaporation pipe network B through the insulation capillary, the three-position three-way solenoid valve outlet 2, and the expansion valve B. The medium-temperature and medium-pressure refrigerant liquid absorbs heat and changes into a low-temperature and low-pressure refrigerant gas. The temperature of the cold storage room around the evaporation pipe network B also drops suddenly; when the temperature of the cold storage room drops to the set temperature, that is, the temperature sensor B detects that the temperature of the cold storage room drops to the set temperature, the MCU microprocessor control circuit closes the three-position three-way solenoid valve outlet 2.

[0017] When the temperature of the refrigerator or freezer rises to the set value, the MCU microprocessor control circuit opens the three-position three-way solenoid valve outlet 1 / outlet 2 again, and the temperature of the freezer / refrigerator is maintained around the set temperature, that is, the refrigerator function is maintained.

[0018] The MCU microprocessor control circuit receives the indoor temperature information from the temperature sensor C; if the room temperature is too high, the three-position three-way solenoid valve outlet 3 and the cross-flow fan are opened, and the medium-temperature and medium-pressure refrigerant liquid flowing out of the condenser pipe network passes through the insulation capillary, the three-position three-way solenoid valve outlet 3, and the expansion valve C into the evaporation pipe network C of the indoor air-conditioning hanging unit, and the medium-temperature and medium-pressure refrigerant liquid enters the evaporation pipe network C along the pipeline, and the medium-temperature and medium-pressure refrigerant liquid absorbs heat and changes into a low-temperature and low-pressure refrigerant gas, and the temperature of the air outlet of the air conditioner around the evaporation pipe network C also drops, and the cross-flow fan blows out cold air; when the indoor temperature drops to the set temperature, the MCU microprocessor control circuit closes the three-position three-way solenoid valve outlet 3; when all three outlets of the three-position three-way solenoid valve are closed, that is, the temperature sensor C detects that the indoor temperature drops to the set temperature, the MCU microprocessor control circuit closes the three-position three-way solenoid valve outlet 3 and the cross-flow fan.

[0019] Subsequently, the low-temperature and low-pressure refrigerant gas flowing out of the evaporator network A, the evaporator network B, and the evaporator network C enters the gas-liquid separation tank along the refrigerant return pipeline, and the low-temperature and low-pressure refrigerant gas coming out of the gas-liquid separation tank outlet enters the compressor again and enters the refrigerant circulation process.

[0020] The upper limit of condensation heat release heating hot water is 55-60 degrees; along with the condensation heat release process, the internal temperature of the condenser water heater rises and approaches 55 degrees; when the water temperature sensor A indicates that the hot water temperature in the lower part of the condenser water heater rises and approaches 55 degrees, the MCU microprocessor control circuit issues a prompt that some hot water needs to be discharged. The MCU microprocessor control circuit turns off the compressor and waits for some hot water to be discharged and the internal temperature of the condenser water heater to drop before working again.

[0021] The benefit of the present invention is that the water heater with both refrigerator and air conditioner functions has the triple functions of a water heater, an air conditioner and an electric refrigerator, and the cost is low; it is equivalent to buying an extra water heater and an air conditioner with the money for buying a refrigerator; many areas are hot for a long time, and the air conditioner is used to cool down and produce hot water at the same time, killing two birds with one stone. The condenser of the heat-dissipating refrigerator is used to replace the electric heating tube of the electric water heater, and the condenser is used to release heat to produce hot water, with a heating efficiency of up to 4.5, which saves electricity and eliminates the risk of electric water heater leakage. Using tap water to absorb phase change heat release, the refrigerator has a refrigeration efficiency of up to 3.5, and the total electric power efficiency is close to 8, achieving zero loss of household appliances, energy saving and high efficiency.

[0037] The MCU microprocessor control circuit 100 starts the compressor 202; the compressor 202 inhales low-temperature and low-pressure refrigerant gas and pumps out high-temperature and high-pressure refrigerant gas, which passes through the insulated thick tube 301 and enters the condenser pipe network 304 in the water tank; the high-temperature and high-pressure refrigerant gas changes phase and releases heat in the condenser pipe network 304, and the condenser pipe network 304 heats the water storage water heater 300; the hot water has a light specific gravity and automatically floats up; at this time, the water temperature A starts to rise, and the water temperature B remains unchanged; the high-temperature and high-pressure refrigerant gas at the rear pushes the medium-temperature and medium-pressure refrigerant liquid at the front forward to the position of the three-position three-way solenoid valve 212.

[0038] The MCU microprocessor control circuit 100 opens the corresponding outlet 1 of the three-position three-way solenoid valve 212, and the medium-temperature medium-pressure refrigerant liquid flowing out of the condenser pipe network 304 passes through the insulation capillary, the outlet 1 of the three-position three-way solenoid valve 212, and the expansion valve A206; it comes out of the expansion valve A206 and enters the evaporation pipe network A204, and the pressure drops suddenly. The medium-temperature medium-pressure refrigerant liquid absorbs heat in the evaporation pipe network A204 and changes into a low-temperature and low-pressure refrigerant gas. The temperature of the freezer around the evaporation pipe network A204 drops suddenly; the fan 218 starts, and the temperature of each part of the freezer tends to be the same. When the temperature of the freezer drops to the set temperature, that is, the temperature sensor A205 detects that the temperature of the freezer drops to the set temperature, the MCU microprocessor control circuit 100 closes the outlet 1 of the three-position three-way solenoid valve 212, and the temperature of the freezer is maintained around the set temperature.

[0039] The MCU microprocessor control circuit 100 opens the three-position three-way solenoid valve 212, and the medium-temperature and medium-pressure refrigerant liquid flowing out of the condenser pipe network 304 enters the evaporation pipe network B208 through the insulation capillary, the three-position three-way solenoid valve 212 outlet 2, and the expansion valve B207. The medium-temperature and medium-pressure refrigerant liquid absorbs heat and changes into a low-temperature and low-pressure refrigerant gas, and the temperature of the cold storage room around the evaporation pipe network B208 also drops suddenly; when the temperature of the cold storage room drops to the set temperature, that is, the temperature sensor B209 detects that the temperature of the cold storage room drops to the set temperature, the MCU microprocessor control circuit 100 closes the three-position three-way solenoid valve 212 outlet 2.

[0040] When the temperature of the refrigerator or freezer rises to the set value, the MCU microprocessor control circuit 100 opens the outlet 1 / outlet 2 of the three-position three-way solenoid valve 212 again, and the temperature of the freezer / refrigerator is maintained around the set temperature.

[0041] The MCU microprocessor control circuit 100 opens the outlet 3 of the three-position three-way solenoid valve 212, and the medium-temperature and medium-pressure refrigerant liquid flowing out of the condenser pipe network 304 enters the evaporation pipe network C400.4 of the indoor air-conditioning hanging unit through the insulation capillary, the outlet 3 of the three-position three-way solenoid valve 212, and the expansion valve C400.3. The medium-temperature and medium-pressure refrigerant liquid enters the evaporation pipe network C400.4 along the pipeline, and the medium-temperature and medium-pressure refrigerant liquid absorbs heat and changes into a low-temperature and low-pressure refrigerant gas. The temperature of the air outlet of the air conditioner around the evaporation pipe network C400.4 also drops and becomes cold air; when the indoor temperature drops to the set temperature, the MCU microprocessor control circuit 100 closes the outlet 3 of the three-position three-way solenoid valve 212; when the three outlets of the three-position three-way solenoid valve 212 are all closed, that is, the temperature sensor C detects that the indoor temperature drops to the set temperature, the MCU microprocessor control circuit 100 closes the outlet 3 of the three-position three-way solenoid valve 212.

[0042] Subsequently, the low-temperature and low-pressure refrigerant gas flowing out from the evaporator network A204, the evaporator network B208, and the evaporator network C400.4 enters the gas-liquid separation tank 211 along the refrigerant return pipe 210, and the low-temperature and low-pressure refrigerant gas coming out of the outlet of the gas-liquid separation tank 211 enters the compressor 202 again and enters the refrigerant circulation process.

[0043] The internal temperature of the condenser water heater rises and approaches 55 degrees; when the water temperature sensor A indicates that the hot water temperature at the bottom of the condenser water heater rises and approaches 55 degrees, the MCU microprocessor control circuit 100 issues a prompt that some hot water needs to be discharged. The MCU microprocessor control circuit 100 turns off the compressor 202 and waits for some hot water to be discharged and the internal temperature of the condenser water heater to drop before working again.

[0044] Calculate the quality of hot water according to the principle of conservation of energy: one kilowatt-hour of electricity is equal to 3,600,000 joules. The initial temperature of tap water is 20 degrees, the temperature difference is 35, and the specific heat capacity of water is 4,200 joules; one kilowatt-hour of electricity can heat, M=3,600,000 / (4,200*35)=24.48 kilograms. One kilowatt-hour of electricity can heat 24.48 kilograms of water to 55 degrees. The heating efficiency of the heat pump is 4.5, 24.48*4.5=110 kilograms. A water heater with both refrigerator and air conditioning functions consumes 1 kilowatt-hour of electricity per day and can produce 110 kilograms of 55-degree hot water. A double-door refrigerator consumes 2 kilowatt-hours of electricity per day and can produce 220 kilograms of 55-degree hot water, a total of 220 liters of hot water, enough for a family of four to cook, wash vegetables and take a bath. If it is not enough, you can use air conditioning to supplement it. In many areas, the hot weather lasts for a long time. It is very pleasant to use air conditioning to cool down and produce hot water at the same time, killing two birds with one stone.

[0045] The benefit of the present invention is that the water heater with both refrigerator and air conditioner functions has the triple functions of water heater, air conditioner and refrigerator, and the cost is low; it is equivalent to buying a water heater and an air conditioner with the money for buying a refrigerator; many areas are hot for a long time, and the air conditioner is used to cool down and produce hot water at the same time, killing two birds with one stone. The heat-deficient refrigerator condenser is used to replace the electric heating tube of the electric water heater to produce hot water, and the heating efficiency is 4.5, which is particularly energy-saving and eliminates the risk of electric water heater leakage; tap water is used to absorb phase change heat release, and the refrigerator refrigeration efficiency is as high as 3.5, and the total electric power efficiency is close to 8, achieving zero loss of household appliances, energy saving and high efficiency.
