Embodiment 1

[0024] A refrigerating cycle system using propane (R290) as a refrigerant, which includes a compressor 2, a reversing valve 3, a condenser 4, an expansion valve 5, and an evaporator 6 connected in sequence via a pipeline 1. The cycle The system is divided into integral circulation system or split circulation system. In order to reduce the possibility of refrigerant leakage as much as possible, the air conditioner indoor unit, air conditioner outdoor unit and the pipeline 1 in the integral circulation system are made into one without intermediate The whole body with connectors, for example, is made into a window air conditioner. Also in order to minimize the possibility of refrigerant leakage, the indoor unit of the air conditioner in the split circulation system and the circulation pipeline 1 can be made into a middle without installation. There is a whole body with connectors, and there is only one connection joint between the pipeline 1 and the outdoor unit in the whole body....

Embodiment 2

[0026] On the basis of Example 1, the present invention can be provided with a quick-connect connector with good airtightness between the air-conditioning indoor unit in the split circulation system and the circulation pipeline 1, and this joint also has good Excellent sealing, because it is a quick-connect plug-and-connect refrigerant leakage is very small during the plug-in process.

Embodiment 3

[0028] On the basis of Embodiment 1 or 2, in order to minimize the amount of refrigerant used in the present invention, the outer diameter of the U-shaped tube inside the condenser or evaporator is 5mm-7mm.

Abstract

The invention discloses a refrigeration cycle system using propane as a cooling medium, and relates to a cooling medium cyclic refrigeration system. The system comprises a compressor, a reversing valve, a condenser, an expansion valve and an evaporator which are orderly connected by a pipeline. The cycle system has two types, i.e. an integral type and a split type. Indoor unit and outdoor unit ofthe air conditioner and the pipeline in the integral type cycle system are made into an integral body without connecting pieces. The indoor air conditioner and the cycle pipeline in the split type cycle system are made into an integral body without connecting pieces. The cooling medium refrigeration cycle system has the advantages of energy saving, safety, environmental protection and low cost.

Description

technical field [0001] The invention relates to a refrigerant cycle refrigeration system, in particular to a refrigeration cycle system using propane as a refrigerant. Background technique [0002] The working process of the existing air conditioner is that the refrigerant circulates in the compressor, reversing valve, condenser, expansion valve, evaporator, and connecting pipelines. In the cooling mode, the compressor discharges the high-temperature and high-pressure gaseous refrigerant, and enters the condenser of the outdoor unit through the four-way reversing valve. The high-temperature and high-pressure gaseous refrigerant is cooled in the condenser and becomes a liquid refrigerant. The resistance loss in the device reduces the pressure of the refrigerant, and then the refrigerant passes through a capillary tube or an expansion valve or a throttling element to throttle and reduce pressure, and becomes a low-temperature and low-pressure gas-liquid mixed refrigerant, and ...
