Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning heat pump compressors, specifically a bidirectional utilization device for an air conditioning heat pump compressor. Background Technology

[0002] An air conditioner is a device used to control and maintain the temperature, humidity, cleanliness, and airflow of air in a specific space. Its core working principle is based on the refrigeration cycle, which includes four processes: compression, condensation, expansion, and evaporation. The refrigerant circulates in the air conditioning system, absorbing and releasing heat through phase change, thereby regulating the indoor temperature.

[0003] However, traditional air conditioners typically only support a single cooling or heating mode, making it difficult to meet both cooling and heating needs simultaneously. This requires additional equipment, increasing costs. Furthermore, existing dual-mode air conditioners rely on multiple independent circuits, resulting in complex valve switching logic, high failure rates, and direct discharge of waste heat generated during cooling into the environment. During heating, additional electrical energy is required, leading to low energy utilization. Therefore, those skilled in the art have proposed a bidirectional utilization device for air conditioning heat pump compressors to address the problems mentioned in the background art.

[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0018] Example:

[0019] Please see Figure 1As shown, a bidirectional utilization device for an air conditioning heat pump compressor includes a compressor 1. An outlet reversing valve 2 is connected to the outlet of the compressor 1 via a pipe. The outlet of the outlet reversing valve 2 is divided into two paths: one path is connected to a first reversing valve 15, and the other path is connected to a second reversing valve 16. The outlet of the first reversing valve 15 is connected to a first heat exchanger 4. The cooling outlet of the first heat exchanger 4 is connected to a second heat exchanger 10. A throttling device 11 is connected between the first heat exchanger 4 and the second heat exchanger 10 via a pipeline. The outlet of the second reversing valve 16 is connected to outdoor fan fins. 14. The outlet of the outdoor fan fin 14 is connected to a third reversing valve 17. The third reversing valve 17 is connected to a liquid storage tank 3 via a pipeline. The outlet of the liquid storage tank 3 is connected to a filter drying tank 5. The filter drying tank 5 is connected to the inlet of the compressor 1 via a pipeline. The heat exchange medium of the first heat exchanger 4 and the second heat exchanger 10 are respectively connected to the first insulated hot water storage tank 6 and the second insulated hot water storage tank 8 through circulation pipelines. The compressor 1 is used to compress the low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure vapor to provide circulation power for the system. The outlet reversing valve... 2 is used to control the airflow direction at the compressor 1 outlet and distribute refrigerant to different circuits. The first reversing valve 15 is used to switch the refrigerant flow direction, determining whether high-temperature steam enters the first heat exchanger 4 or the outdoor fan fins 14. In the heating state, the second reversing valve 16 adjusts the refrigerant path to the outdoor fan fins 14 or the liquid receiver 3. In the auxiliary mode switching, in the heating state, the first heat exchanger 4 transfers the heat of the high-temperature refrigerant to the first insulated hot water storage tank 6. In the cooling state, the second heat exchanger 10 absorbs heat to generate cold air, cooling the second insulated hot water storage tank 8. The throttle valve 11 reduces pressure to achieve a phase change in the refrigerant, providing conditions for evaporation and heat absorption. The third reversing valve 17 controls the refrigerant to flow back from the second heat exchanger 10 or the liquid receiver 3, ensuring the integrity of the circulation path. The liquid receiver 3 stores liquid refrigerant, balances system pressure fluctuations, and ensures stable refrigerant flow back to the compressor 1. The filter dryer 5 filters refrigerant impurities and absorbs moisture to prevent system blockage or corrosion. The first insulated hot water storage tank 6 and the second insulated hot water storage tank 8 are used to store hot water and cold water, respectively, reducing heat loss.

[0020] Specifically, the shells of the first insulated hot water storage tank 6 and the second insulated hot water storage tank 8 are double-layer stainless steel structures with polyurethane foam insulation material filling the interlayer. The inner walls of the first insulated hot water storage tank 6 and the second insulated hot water storage tank 8 are respectively fixed with a first temperature sensor 7 and a second temperature sensor 9. The first temperature sensor 7 and the second temperature sensor 9 are used to monitor the temperature of the first insulated hot water storage tank 6 and the second insulated hot water storage tank 8 in real time and trigger the reversing valve to switch the working mode.

[0021] Furthermore, the throttle valve 11 is an adjustable electronic expansion valve, whose inlet is connected to the refrigerant outlet of the first heat exchanger 4 via a copper pipe, and whose outlet is connected to the refrigerant inlet of the second heat exchanger 10 via a copper pipe.

[0022] Furthermore, the two outlets of the first reversing valve 15 are respectively connected to the refrigerant inlet of the first heat exchanger 4 and the inlet of the outdoor fan fin 14, the two outlets of the second reversing valve 16 are respectively connected to the inlet of the outdoor fan fin 14 and the inlet of the liquid receiver 3, and the two inlets of the third reversing valve 17 are respectively connected to the refrigerant outlet of the second heat exchanger 10 and the inlet of the liquid receiver 3.

[0023] Furthermore, a first check valve 12 is installed on the pipe between the refrigerant outlet of the first heat exchanger 4 and the throttle 11, and a second check valve 13 is installed on the pipe between the refrigerant outlet of the second heat exchanger 10 and the liquid storage tank 3. The valve bodies of the first check valve 12 and the second check valve 13 are both oriented towards the refrigerant flow direction. The first check valve 12 and the second check valve 13 are used to ensure unidirectional flow of refrigerant and avoid backflow interfering with system operation.

[0024] Furthermore, the outdoor fan fin 14 includes an aluminum fin array and an axial fan. The fin array is connected to the outlet of the second reversing valve 16 and the inlet of the third reversing valve 17 via copper pipes. The aluminum fin array is used to accelerate heat dissipation or heat absorption, and the axial fan is used to enhance airflow efficiency.

[0025] As can be seen from the above, this device has three operating states:

[0026] 1. Cooling and heating state: The compressor 1 discharges high-temperature steam, which is distributed to the first reversing valve 15 through the outlet reversing valve 2 and guided to the first heat exchanger 4 to heat the first insulated hot water storage tank 6. After the refrigerant releases heat, it is depressurized through the throttle 11 and enters the second heat exchanger 10 to evaporate and absorb heat, cooling the second insulated hot water storage tank 8. The low-temperature gaseous refrigerant flows back to the compressor 1 through the liquid storage tank 3 to complete the cycle.

[0027] 2. Heating state: When the second temperature sensor 9 detects that the temperature of the second insulated hot water storage tank 8 has reached the set lower limit, the second reversing valve 16 switches, and the refrigerant is cooled by the outdoor fan fins 14 and then enters the second heat exchanger 10 through the throttle 11 to absorb heat. The evaporated refrigerant flows back to the compressor 1 through the liquid storage tank 3 to continuously heat the first insulated hot water storage tank 6.

[0028] 3. Cooling state: When the first temperature sensor 7 detects that the temperature of the first insulated hot water storage tank 6 has reached the set upper limit, the first reversing valve 15 switches, and the high-temperature steam is cooled by the outdoor fan fins 14 and enters the second heat exchanger 10 for evaporation and cooling. The cooling capacity is transferred to the second insulated hot water storage tank 8, and the refrigerant flows back to the compressor 1 through the liquid storage tank 3 to complete the refrigeration cycle.

[0029] By employing three sets of reversing valves for coordinated control, a single system can simultaneously perform cooling, heating, and dual-mode operation without the need for additional equipment, thus reducing equipment costs and adapting to various scenarios. The coordinated design of dual heat exchangers and insulated water tanks improves the waste heat recovery rate of cooling and reduces heating energy consumption. Temperature sensors are linked with reversing valves to achieve fully automatic mode switching, reducing operation and maintenance costs.

The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art.
