Cold medium leakage-proof regulator for building air conditioning system

Abstract

The invention relates to the technical field of air conditioning and particularly relates to a cold medium leakage-proof regulator for a building air conditioning system. The cold medium leakage-proof regulator comprises a compressor, an evaporator, a throttle valve and a condenser, a cold medium channel between the throttle valve and the condenser, and a solenoid valve and a pressure sensor which are arranged on the cold medium channel, wherein a mass flow sensor and a mass flow regulation device are arranged between the compressor and the evaporator; the mass flow regulation device comprises a foundation pipeline and a stepping pipeline; the foundation pipeline is internally provided with a transverse cold medium through hole and a longitudinal mounting hole; an elastic bulge is arranged on an inner side wall in the mounting hole; the stepping pipeline is transversely provided with an regulation hole and a groove; an electric retractable rod and a stepping motor are arranged at the top of the stepping pipeline; and a cold medium detector is arranged on the cold medium channel. The cold medium leakage-proof regulator for the building air conditioning system can be used for comprehensively monitoring a cold medium leakage problem and pertinent regulation and control measures are adopted, so that the safety of the air conditioning system is improved; and meanwhile, a proper cold medium mass flow can be regulated aiming at different mounting conditions and working conditions.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a refrigerant leak-proof regulator used in building air conditioning systems. Background technique [0002] The refrigerant in the air conditioner is generally R290 or R717, etc. The main component of R290 is propane, which is a non-toxic refrigerant with stable chemical properties, but it is a flammable and explosive gas. Once the refrigerant leaks and cannot be dealt with in time , it is very likely to cause safety accidents, including other refrigerants, if leakage occurs, it will bring safety hazards. Therefore, it is necessary to take leak-proof measures and leak detection monitoring for the refrigerant channel in the air conditioner to prevent problems before they happen, eliminate potential safety hazards, and ensure the safety of the air conditioner.
