Air conditioner built-in system utilizing superheat degree for humidity control and method

Abstract

The invention discloses an air conditioner built-in system utilizing the superheat degree for humidity control and a method. The air conditioner built-in system comprises a driving circuit unit, a temperature and humidity sensor unit, an AD conversion unit, a humidity processing unit and a computing control unit; and temperature analog signals and humidity analog signals are obtained through the temperature and humidity sensor unit, converted through the AD conversion unit and then transmitted to the humidity processing unit and the computing control unit to be processed, the current return-air superheat degree is obtained, and by comparing the current return-air superheat degree with the target superheat degree and comparing the current indoor environment humidity with the target humidity, whether the opening degree of an electronic expansion valve is adjusted or not is determined. The air conditioner built-in system adopts a method for controlling the humidity through the superheat degree, the opening degrees of the electronic expansion valve is controlled through a precise humidity control technology, thus the refrigerant flow is controlled, the adjusting demand of people on theindoor environment humidity can be met by an air conditioner in a more energy-saving mode, the humidity control precision is improved, and the comfort of using the air conditioner is improved.

Description

technical field [0001] The invention relates to air-conditioning control technology, in particular to an air-conditioning built-in system and method for humidity control using superheat. Background technique [0002] As a refrigeration or heating device, air conditioners have become a part of people's lives, and they can actually improve the comfort of people's lives. In order to better improve the comfort of users, the air conditioner needs to detect the humidity, and realize the function of the air conditioner through the variable of humidity. At present, the air conditioner controls the humidity of the room air conditioner through a dehumidification method. The current dehumidification method mainly achieves the purpose of dehumidification by controlling the evaporation temperature. However, for a complete set of air conditioning and refrigeration systems, the evaporation temperature is related to the wind speed and the flow rate of the refrigerant, and the humidity is ...
