Embodiment Construction

[0017] figure 1 , 2 Among them, the air conditioner is mainly composed of compressor 1, indoor heat exchanger 2, outdoor heat exchanger 3, throttling compensation capillary

[0018] Composed of 4, the indoor heat exchanger 2 and the outdoor heat exchanger 3 are respectively connected to the compressor 1, and the indoor heat exchanger 2 and the outdoor heat exchanger 3 are connected by a throttling compensation capillary 4. The throttle compensation capillary 4 is welded into a pipe body by the compensation capillary 41 and the throttle capillary 42 with different diameters and lengths, wherein one end of the compensation capillary 41 communicates with the outlet of the outdoor heat exchanger 3, and the throttle capillary 42 One end communicates with the outlet of the indoor heat exchanger 2. The diameter of the compensation capillary 41 is larger than that of the throttling capillary 42. The flow rate of the compensation capillary is 2.0-20.0 L / min under the pressure of 0.1 M...

Abstract

The invention relates to an air conditioner of a refrigerating and heating shared capillary tube. The air conditioner comprises a compressor, an indoor heat exchanger and an outdoor heat exchanger; the indoor heat exchanger and the outdoor heat exchanger are communicated through the throttling compensation capillary tube, the throttling compensation capillary tube is formed by integral welding or split connection of a throttling capillary tube body and a compensation capillary tube body, one end of the throttling capillary tube body is communicated with an outlet tube of the indoor heat exchanger, and one end of the compensation capillary tube body is communicated with an outlet tube of the outdoor heat exchanger. The shared throttling compensation capillary tube is adopted, the manufacturing manhour and the debugging time can be greatly reduced, the cost is reduced to the maximum degree, machining, mounting and maintaining are more convenient and rapid, the refrigerating and heating effect is good, and the service life of the air conditioner is prolonged.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner with a shared capillary tube for cooling and heating. Background technique [0002] Existing heating and cooling air conditioners are generally composed of a compressor, an outdoor heat exchanger, an indoor heat exchanger, etc., and the outdoor heat exchanger and the indoor heat exchanger are communicated with the heating capillary through independent cooling capillary tubes. The amount of refrigerant circulation in the refrigeration cycle and the heating cycle is generally different, so the check valve controls the flow of the refrigerant to different capillary tubes during cooling and heating to achieve the refrigerant circulation required for cooling and heating respectively, so that To achieve the effect of cooling and heating, since the check valve is used to control the flow of refrigerant to different capillary tubes during heating, special tools are required to wel...
