Air conditioning unit with non-condensable gas cleaning function

Abstract

The invention provides an air conditioning unit with a non-condensable gas cleaning function. The air conditioning unit comprises an evaporator, a condenser and a cleaning structure, wherein an inlet,an exhaust port and a liquid return port are formed in the cleaning structure, the condenser is provided with a gaseous outlet, the gaseous outlet is communicated with the inlet, the liquid return port is communicated with the evaporator, the exhaust port is communicated with the outside, and the mixed gas in the condenser is separated in the cleaning structure to form liquid refrigerant and gaseous non-condensable gas. The air conditioning unit is advantaged in that the non-condensable gas and the refrigerant are separated according to different liquefaction conditions by utilizing a cleaning structure, liquefied refrigerants flow back to the unit, the gaseous non-condensable gas is exhausted out of the unit, a purpose of cleaning the non-condensable gas of the system is achieved in cooperation with on-off control over a gas taking valve, an exhaust valve and a liquid return valve, reliability and performance of the unit are effectively improved, and running reliability of the unit is guaranteed.

Description

technical field [0001] The invention relates to the technical field of refrigerant heat exchange devices, in particular to an air conditioner unit with the function of cleaning non-condensable gas. Background technique [0002] In the centrifugal water-cooled chiller system with negative pressure working medium, due to the physical characteristics of the negative pressure working medium, the evaporator is in a negative pressure state during the operation of the unit. Leakage in the evaporator causes the refrigerant to be mixed with air, resulting in a decrease in the performance of the unit. The air entering the refrigerant system is compressed by the compressor and enters the condenser. However, in the condenser, the gaseous refrigerant is exchanged with the cooling water. Heat, condensed into a liquid refrigerant, and the air mixed into the system cannot be condensed under the pressure of the condenser and the temperature of the cooling water, and becomes a non-condensable...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problem in the prior art that the performance of the unit is affected because the non-condensable gas does not participate in heat exchange, an air conditioning unit with the function of cleaning the non-condensable gas is provided, which separates the non-condensable gas from the refrigerant according to the liquefaction conditions
