Method and system of passenger car air conditioner for regulating temperature through intelligent combined control on temperature and humidity

Abstract

Disclosed is a method of a passenger car air conditioner for regulating temperature through intelligent combined control on temperature and humidity. The method of the passenger car air conditioner for regulating the temperature through the intelligent combined control on the temperature and the humidity includes following steps: 1) arranging an ambient temperature sensor, a car compartment temperature sensor, an air outlet temperature sensor and a humidity sensor between an evaporator air return inlet and an evaporator core which are located in the passenger car air controller, and using the sensors to send collected temperature and humidity signals into the passenger car air condition controller; 2) introducing a human comfort temperature and humidity curvilinear function into the passenger car air condition controller in advance, and comparing the human comfort temperature and humidity curvilinear function with the obtained temperature and humidity signals; 3) then, using an approximation calculation control mode according to a comparative result, outputting a control signal to regulate running of a compressor, rotation speed of a condenser and an evaporator fan and starting and stopping of a water pump, and thereby controlling the temperature and the humidity of air in a passenger car in a comfort range of a human body. Compared with the prior art, the method of the passenger car air conditioner for regulating the temperature through the intelligent combined control on the temperature and the humidity achieves the intelligent combined control on the temperature and the humidity when the passenger car air conditioner is used to cool, heat and ventilate the passenger car.

Description

technical field [0001] The invention relates to a vehicle air-conditioning system, in particular to a passenger car air-conditioning technology used in large and medium-sized public buses with high comfort requirements and dual-purpose heating and cooling. Background technique [0002] At present, traditional passenger car air conditioners generally adopt the single-cooling mode, and the heater is used at the bottom of the car. This mode is used in the airtight car body space. When fresh air needs to be introduced, due to the low temperature outside the car in winter, it is blown out from the air duct and directly to the human body. , will produce a strong sense of cold wind, which is easy to cause harm to the human body. The traditional air conditioner for heating and cooling passenger cars still simply controls the temperature in the passenger car, and the humidity related to comfort is not controlled separately, which may easily cause the temperature and humidity in the c...
