Description

Technical Field

[0001] The present invention relates to the field of air conditioners, and particularly to a blade-type evaporative condensation fluorine pump air conditioning system. Background Art

[0002] Existing air conditioning systems mainly include an indoor unit and an outdoor unit. An expansion valve and an evaporator are provided in the indoor unit, and a compressor and a condenser are provided in the outdoor unit.

[0003] During refrigeration operation, the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gas state and sends it to the condenser for cooling. After cooling, it condenses into a medium-temperature and high-pressure liquid refrigerant and enters the drying and filtering component for filtering. The medium-temperature liquid refrigerant is throttled and depressurized by the expansion valve into a low-temperature and low-pressure gas-liquid mixture, which vaporizes by absorbing heat from the air in the evaporator and becomes a gas state, and then returns to the compressor to continue compression, and the cycle is carried out for refrigeration; during heating operation, the functions of the indoor evaporator and the outdoor condenser are interchanged through pipelines, and the refrigerant in the refrigeration system is used to condense and release heat to heat the indoor air.

[0004] Existing air-cooled condensation air conditioning systems have high energy consumption during operation, especially in high-temperature environments, with poor refrigeration effects and low energy efficiency ratios. Traditional air conditioning systems mainly rely on compressors for refrigeration, and in low-temperature climate conditions, the operation of the compressor is not always necessary, resulting in energy waste; in addition, the condensers of traditional air conditioning systems usually adopt air-cooled methods, with problems of high condensation temperature and poor heat dissipation effects.

[0007] Preferably, the blade type evaporation condensation assembly includes a water tank, a blade type evaporation condenser arranged above the water tank, and a spraying device arranged above the blade type evaporation condenser and capable of spraying the water in the water tank onto the blade type evaporation condenser.

[0008] Preferably, a float valve is arranged at the inlet of the water tank, and the water tank is connected with a water replenishing device through the float valve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In combination with Figures 1 to 3 The blade type evaporation condensation fluorine pump air conditioning system of the present invention will be further described.

[0017] A blade type evaporation condensation fluorine pump air conditioning system, characterized in that it includes a blade type evaporation condensation assembly 2, a fluorine pump 3, an expansion valve 9, an indoor air conditioner 4, and a compressor 5 that are sequentially connected through a first pipeline 1.

[0018] A first bypass pipeline 6 in parallel with the compressor 5 is arranged between the outlet end of the indoor air conditioner 4 and the inlet end of the blade type evaporation and condensation assembly 2, and a second bypass pipeline 8 in parallel with the fluorine pump 3 is arranged between the outlet end of the blade type evaporation and condensation assembly 2 and the inlet end of the expansion valve 9. Through the arrangement of the first bypass pipeline 6 and the second bypass pipeline 8, the entire air conditioning system can form a compressor cycle refrigeration mode with the compressor 5 as the circulation power, a fluorine pump cycle refrigeration mode with the fluorine pump 3 as the circulation power, and a dual power cycle refrigeration mode with both the compressor 5 and the fluorine pump 3 as the circulation power.

[0019] During the use process, when the temperature sensor arranged on the blade type evaporation and condensation assembly 2 in the air conditioning system senses that the ambient temperature is lower than the refrigerant condensation temperature, the air conditioning system switches to the fluorine pump cycle refrigeration mode, that is, the compressor 5 stops running, and the fluorine pump 3 with a smaller power is used as the power source for forced convection circulation, so that the refrigerant sequentially passes through the fluorine pump 3, the expansion valve 9, the indoor air conditioner 4, the first bypass pipeline 6, the blade type evaporation and condensation assembly 2, and the fluorine pump 3, and circulates in this way to achieve continuous refrigeration of the evaporator of the indoor air conditioner 4 and continuous heat dissipation of the outdoor blade type evaporation and condensation assembly, and the system operates refrigeration to achieve energy saving and efficiency improvement.

[0020] When it is detected that the ambient temperature is at the natural condensation critical temperature of the refrigerant, the air conditioning system switches to the dual power cycle refrigeration mode, that is, the fluorine pump 3 with a small power is used to assist the compressor 5 in circulating the refrigerant, so that the refrigerant flows between the blade type evaporation and condensation assembly 2, the fluorine pump 3, the expansion valve 9, the indoor air conditioner 4, and the compressor 5, and also passes through the first bypass valve and the second bypass valve, and circulates in this way to achieve continuous refrigeration of the evaporator of the indoor air conditioner 4 and continuous heat dissipation of the outdoor blade type evaporation and condensation assembly, and the system operates refrigeration to reduce the running time and running power of the compressor 5, and achieve energy saving and efficiency improvement.

[0021] When it is detected that the ambient temperature is higher than the natural condensation critical temperature of the refrigerant, the air conditioning system switches to the compressor cycle refrigeration mode, and the compressor 5 is used as the power source, so that the refrigerant sequentially passes through the compressor 5, the blade type evaporation and condensation assembly 2, the second bypass pipeline 8, the expansion valve 9, the indoor air conditioner 4, and the compressor 5, and circulates in this way to achieve continuous refrigeration of the evaporator of the indoor air conditioner 4 and continuous heat dissipation of the outdoor blade type evaporation and condensation assembly, and the system operates refrigeration to ensure the air conditioning cooling effect of the air conditioned room.

[0022] In the above process, the blade type evaporation and condensation fluorine pump air conditioning system can use the compressor cycle refrigeration mode, the fluorine pump cycle refrigeration mode, and the dual power cycle refrigeration mode according to the ambient temperature, so that the compressor 5 operates reasonably, significantly improving the energy saving effect; secondly, the efficient condensation of the blade type evaporation and condensation assembly 2 combined with the three operation modes of the entire air conditioning system can further improve the energy efficiency ratio of the air conditioning system. For specific data, please refer to the following table.

[0023] The following table is Table 1, which shows the refrigeration energy efficiency ratio data of a conventional air-cooled condensing fluorine pump air conditioner in various temperature environments: Table 1: The following table is Table 2, which shows the refrigeration energy efficiency ratio data of the blade type evaporative condensing fluorine pump air conditioner system in this embodiment in various temperature environments: Table 2: The outdoor unit condensation air volume of the blade type evaporative condensing fluorine pump air conditioner system is approximately half of that of the conventional air-cooled condensing fluorine pump air conditioner, and the fan power is relatively small.

[0024] The following table is Table 3, which shows the comparative data of the refrigeration energy efficiency ratio of this embodiment and the conventional air-cooled condensing fluorine pump air conditioner in various temperature environments: Table 3: According to the experimental test data in Tables 1 to 3, the refrigeration energy efficiency ratio of the conventional air-cooled condensing air conditioner is 2.82 - 5.79, the energy efficiency ratio of the dual-power cycle refrigeration mode is 7.36, and the energy efficiency ratio of the fluorine pump cycle refrigeration mode is 9.92 - 10; in this embodiment, the energy efficiency ratio of the compressor cycle refrigeration mode is 4.45 - 6.15, the energy efficiency ratio of the dual-power cycle refrigeration mode is 7.95, and the energy efficiency ratio of the fluorine pump cycle refrigeration mode is 11.03 - 11.11. By comparison, it can be seen that the blade type evaporative condensing fluorine pump air conditioner system has a significant energy-saving effect during refrigeration compared to the conventional air-cooled condensing fluorine pump air conditioner system.

[0025] In the structure of the blade type evaporative condensing component 2, it includes a water tank 23, a blade type evaporative condenser 21 arranged above the water tank 23, and a spraying device 22 arranged above the blade type evaporative condenser 21 and capable of spraying the water in the water tank 23 onto the blade type evaporative condenser 21.

Finally, the cooling water drips back into the water tank, significantly improving the condensation effect of the refrigerant in the blade type evaporative condenser.

[0027] A float valve 231 is provided at the inlet of the water tank 23. The water tank 23 is connected to a water replenishing device through the float valve 231. The water replenishing device can be a water pipe. When the water level in the water tank is relatively low, cooling water can be timely replenished into the water tank through the float valve.

[0028] The blade type evaporative condenser includes heat dissipation plates and a condensing pipe that passes back and forth through multiple heat dissipation plates. There are multiple heat dissipation plates and they are arranged parallel to each other. Each heat dissipation plate has multiple through holes. The condensing pipe sequentially passes back and forth through the through holes on each heat dissipation plate and contacts the heat dissipation plates, increasing the heat dissipation area. The spray head 221 sprays cooling water onto the condensing pipe and the heat dissipation plates to achieve an efficient condensation effect.

[0029] The first bypass pipeline 6 includes a second pipeline 62 connected between the outlet end of the indoor air conditioner 4 and the inlet end of the blade type evaporative condensation assembly 2 and a second one-way valve 61 provided on the second pipeline 62. The second bypass pipeline 8 includes a third pipeline 82 connected between the outlet end of the blade type evaporative condensation assembly 2 and the inlet end of the expansion valve 9 and a third one-way valve 81 provided on the third pipeline 82.
