Problems solved by technology

Although the temperature of the air outlet on the indoor side is higher than the room temperature, it is still heating, but because the inlet air temperature is low, the outlet air temperature may still be lower than the human body surface temperature, making people feel that the air conditioner does not heat and blows cold air.
At this time, the heating capacity of the air conditioner is also low, and the room temperature rises slowly, which also makes people feel that the heating effect of the air conditioner is poor.

Abstract

The invention discloses an air condition that carries low temperature heating function and the method to control. A temperature sensor that can detect the running mode of the air condition is set in it. The sensor connects to a controller that is set a temperature reference value in it. The controller would control the air condition to run in the mode of low temperature heating by the result of comparing the detecting signal and the reference value. When in low temperature heating mode, the controller outputs control signal to control the relay to adjust the fan motor running in low speed mode, and control the assistant electric heater to start. The invention could obviously increase the blow temperature when heating and improve the effect of low temperature heating.

Description

technical field [0001] The invention belongs to the field of air conditioners, and relates to a heating and cooling air conditioner with a low-temperature heating function, and more specifically relates to a heating and cooling air conditioner that automatically adjusts the operating parameters of the air conditioner according to the working conditions of the air conditioner. Background technique [0002] The refrigeration system of the existing heat pump heating and cooling air conditioner is composed of a compressor, a four-way reversing valve, a condenser, a throttling component and an evaporator; the electric control system includes a controller, a sensor, a control valve, an auxiliary electric heating device and a fan motor and other parts. Usually, during heating operation, the air conditioner uses the heat pump heating principle to transfer heat from the outdoors to the indoors through the work of the compressor. The compressor sends the high-temperature and high-pre...
