Air return temperature regulating sedan air conditioner

Abstract

The invention related to air condition of saloon car, especially to air return thermoregulated air condition of saloon car. The air condition includes air intake dual duct, refrigeration air duct, and air out duct. A blower fan is setup in the air intake dual duct. Air inlet of air intake dual duct is composed of fresh air inlet, air return inlet, and regulating door for fresh air setup between the fresh air inlet and the air return inlet. Evaporator of air conditioning unit is setup in the refrigeration air duct. Characters are that conduction through air duct insulated from refrigeration air duct is added between the air intake dual duct and air out duct. Air outlet of the conduction through air duct, and air outlet of the refrigeration air duct are led to the air out duct. The invention is in favor of reducing energy consumption caused by heating blast of air condition repeatedly.

Description

technical field [0001] The invention relates to a car air conditioner, in particular to a return air temperature-adjusting car air conditioner for adjusting the air temperature of the air conditioner. Background technique [0002] Due to the limitations of the space structure and adjustment accuracy of the existing automatic air conditioner with integrated cooling and heating, the structural schematic diagram and schematic diagram of the air supply, heating, temperature adjustment and air conditioning device are as follows figure 1 and image 3 As shown, it is basically composed of an air inlet mixing air duct 1, a cooling air duct 2 and an air outlet air duct 3 connected in sequence; It consists of a fresh air inlet 12 for inputting supplementary fresh air, a return air inlet 13 for inputting circulating air, and a fresh air regulating damper 14 located between the fresh air inlet and the return air inlet; the total circulating air volume is regulated by the speed of the f...

Problems solved by technology

The disadvantages of this air treatment method are: (1) In order to achieve the comfort standard of the air conditioner, the temperature of the air supply in the car is required to be above 10-15°C, while the temperature of the air outlet of the evaporator is generally between 2-7°C, and the heating temperature difference In order to adjust the comfortable air supply temperature, the air is cooled and dehumidified by the evaporator, and then heated by the heater, which wastes a lot of cooling capacity; (2) The intake volume of fresh air and the circulation air The amount of air intake has not been adjusted accurately, so an excessive amount of fresh air (hereinafter referred to as fresh air) is often supplemented, resulting in excessive energy consumption of fresh air
