Abstract

The invention discloses an air conditioner and an air supply control method applied to the air conditioner. Among them, the air conditioner includes: a compressor with a suction end, an exhaust end, and an air supply end; a four-way valve; an indoor heat exchanger, the first end of which is connected to the third interface of the four-way valve; an outdoor heat exchanger, The first end is connected to the fourth port of the four-way valve; the liquid reservoir is connected to the second end of the outdoor heat exchanger through the first liquid pipe, and connected to the second end of the indoor heat exchanger through the second liquid pipe. connected to the gas supply end of the compressor through the air pipe; the first throttling element is arranged on the first liquid pipe; the second throttling element is arranged on the second liquid pipe; and the third throttling element is connected to Between the first node and the makeup side of the compressor. The invention solves the problem in the prior art that a single air supply circuit cannot guarantee the normal operation of the air conditioner in a low-temperature environment, thereby ensuring the operation effect of the air conditioner and improving the operation stability and reliability of the unit.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and an air supply control method applied to the air conditioner. Background technique [0002] Existing air conditioners have a large attenuation of heating capacity when the temperature is relatively low in cold winter, insufficient heating, or even fail to operate normally; It cannot operate normally, which makes it difficult for the air conditioner to meet the needs of ultra-low temperature heating or ultra-high temperature cooling. At the same time, the system energy efficiency of the air conditioner will also be limited by the suction volume of the compressor. Therefore, in recent years, many enterprises and scholars have adopted the quasi-two-stage compression cycle (gas supplementation and enthalpy increase cycle) to solve the shortcomings of conventional air conditioners at ultra-low temperature or ultra-high temperature; the patent application number is...
