Low pressure control and energy adjustment device used for air conditioner

Abstract

The invention relates to a low pressure control and energy adjustment device used for an air conditioner. The low pressure control and energy adjustment device comprises a condenser and further comprise a liquid storage, a drying filter, a level glass, an evaporator and a compressor and an air conditioner control system which are sequentially connected with the condenser. A hot gas bypass device is mounted between the level glass and the condenser and comprises a three-way connector A, a three-way connector B, an electromagnetic valve A, an electromagnetic valve B, an electromagnetic valve C, a hot gas jet chamber A and a hot gas jet chamber B. The low pressure control and energy adjustment device has the beneficial effects that self energy output can be adjusted according to load changes of the interior where the air conditioner is located to keep the stable temperature and stable humidity of the interior, and when gas suction pressure of the compressor is lower than a low pressure control value, the gas suction pressure of the compressor is adjusted, frequent start and stop of the compressor are avoided, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a low-voltage control and energy regulating device for air conditioning. Background technique [0002] At present, many places require air conditioners to adjust the temperature for 24 hours, and require air conditioners to be safe, reliable, and stable. Existing air-conditioning compressors are equipped with low-voltage protection devices, which stop working when the suction pressure of the compressor is low. When the indoor temperature is close to the set temperature, the compressor will stop working and restart frequently, which will affect the service life of the compressor; The air conditioner cannot adjust the energy output in time, and cannot maintain a stable indoor temperature and humidity. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a low-voltage control and energy re...
