Efficient-heat-exchange air conditioner refrigeration circulating system and air conditioner

Abstract

The invention discloses an efficient-heat-exchange air conditioner refrigeration circulating system which comprises a compressor, a coolant condenser, a coolant evaporator, an indoor unit heat exchanger, an expansion valve and a heat dissipator, wherein a high-pressure output end of the compressor is communicated with one end of the coolant condenser; the other end of the coolant condenser is communicated with one end of the coolant evaporator through a pipeline; the pipeline is provided with the expansion valve; the other end of the coolant evaporator is communicated with a low-pressure input end of the compressor; the coolant condenser is externally connected with the heat dissipator; the coolant evaporator is externally connected with the indoor unit heat exchanger; a heat-conducting medium, which directly contacts the coolant, is respectively arranged in the coolant condenser and coolant evaporator; the heat-conducting medium is a solid heat conductor; the solid heat conductor in the coolant condenser is connected with the heat dissipator; and the solid heat conductor in the coolant evaporator is connected with the indoor unit heat exchanger. By adopting the solid heat conductor as the heat-conducting medium, the structure of the traditional air conditioner refrigeration circulating system is changed; and the system has the advantages of simpler structure arrangement, higher heat transfer rate and better effect.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning refrigeration cycle system with high heat exchange and an air conditioner. Background technique [0002] An air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, condensation process, expansion process, and evaporation process. When the air conditioner is in the refrigeration cycle, the refrigerant compressed by the compressor and turned into a high-temperature and high-pressure state can flow to the condenser under the guidance of the four-way valve, and radiate heat to the outside in the outdoor unit heat exchanger, and then flow through the expansion valve. Significantly lowering its temperature and pressure, the low-temperature, low-pressure refrigerant absorbs heat as it passes through the evaporator and flows back into the compressor. Among them, the compres...

Problems solved by technology

[0003] Air conditioners are usually divided into household air conditioners and commercial air conditioners. Commercial air conditioners are mainly used in large buildings such as office buildings and shopping malls. At present, the condensation process of the refrigeration cycle system of commercial air conditioners uses cooling water (cold source) to take away the outdoor unit for replacement. The heat generated by the condensation of the refrigerant in the heater, the cooling water is circulated and cooled by the cooling tower, the water circulation requires a large number of water pumps, the structure is complicated to install, and the power consumption is large, and the air conditioner uses circulating cooling water for a long time, and the cooling water is easy to breed and reproduce mold and The environment inside the air conditioner is unsanitary; and during the evaporation process, the refrigerant absorbs the heat of the indoor air (heat source) to cool the air, but the heat exchange efficiency between the refrigerant and the air is not high. How to improve the heat exchange of the indoor unit heat exchanger? Exchange efficiency is our problem to be solved
