Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a low-energy consumption air conditioning based on a separate heat pipe heat exchanger. Background Art

[0002] Air conditioning, or air conditioning, refers to the use of various technologies and equipment to adjust the temperature, humidity, cleanliness and flow rate of air in a certain area or space to meet people's comfort requirements or different process environment requirements. Air conditioning generally includes a compressor, a condenser, and an evaporator. The compressor is used to compress the gas, turning the low-pressure gas into a high-pressure gas, providing the refrigerant with energy to absorb heat from the high-temperature environment and release heat to the high-temperature environment, helping the refrigerant cycle to proceed smoothly; the condenser is used to condense the refrigerant from gas to liquid and release heat; the evaporator is used to evaporate the refrigerant from liquid to gas and absorb heat.

[0003] During the operation of the air conditioner, when the air conditioner is cooling, the refrigerant first passes through the compressor to become a high-pressure gas; then it passes through the condenser to condense and release heat to become a high-pressure liquid; then the high-pressure liquid passes through the throttling device and becomes a low-temperature, low-pressure liquid; then it passes through the evaporator to evaporate and absorb heat to become a low-temperature, low-pressure gas, and finally returns to the compressor. When the air conditioner is heating, the refrigerant first passes through the compressor to become a high-pressure gas, then it passes through the condenser to condense and release heat to become a high-pressure liquid; then the high-pressure liquid passes through the throttling device and becomes a low-temperature, low-pressure liquid; then it passes through the evaporator to evaporate and absorb heat to become a low-temperature, low-pressure gas, and finally returns to the compressor.
