Gas supplementing and enthalpy increasing pipeline system for air conditioner

Abstract

The invention relates to the technical field of air conditioners, in particular to a gas supplementing and enthalpy increasing pipeline system for an air conditioner. The gas supplementing and enthalpy increasing pipeline system for an air conditioner aims to solve the problem that the effect of a noise elimination and vibration reduction device of a gas supplementing and enthalpy increasing pipeline in an existing air conditioner is poor. Therefore, according to the gas supplementing and enthalpy increasing pipeline system, two noise elimination and vibration reduction device are arranged inwhich the cross-sectional area of the cylinder bodies are larger than the maximum cross-sectional area of the connecting pipe, so that the gas supplementing and enthalpy-increasing pipeline is provided with a plurality of pipelines with sudden cross-section mutation, the energy of most of fluid pulses in the gas supplementing and enthalpy increasing pipeline is consumed in the noise eliminating and vibration reducing device, so that the effect of the fluid pulse butting tube is reduced; the lengths of the barrel bodies of the two noise elimination and vibration damping devices are different, so that the passing frequencies of the two noise eliminating and vibration damping devices are staggered with each other so as to improve the frequency characteristics of the noise eliminating and vibration damping device, so that the noise elimination and vibration reduction effect is improved; a spray hole is formed in the connecting pipe of the cylinder body at the air outlet end of the cylinderbody, the energy of the fluid pulse is further consumed by the damping action of the spray hole so as to improve the noise elimination and vibration reduction effect.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a pipeline system for replenishing air and increasing enthalpy for an air conditioner. Background technique [0002] The compressor is one of the most important devices of the air conditioner. When the external environment temperature is low, due to the relatively low evaporating pressure, the compressor suction specific capacity is relatively large, which reduces the output efficiency of the compressor. In order to solve the above problems, the air-enhancing compressor is applied to the air conditioner to solve the problem that its heating efficiency may not meet the demand when the outdoor ambient temperature is low. However, the internal pressure of the air supplement enthalpy increasing compressor presents periodic high and low changes during operation, and the pressure of the refrigerant in the air supplement enthalpy increasing pipeline is not constant...
