Control method for improving outlet air temperature comfort of air conditioner

Abstract

The invention discloses a control method for improving outlet air temperature comfort of an air conditioner. A cold air preventing temperature value is not a fixed parameter value but a function of environmental temperature, namely the cold air preventing temperature value TE is the function of the environmental temperature T1. By setting a maximum limit value and a minimum limit value of the cold air preventing temperature value, and in the range of the maximum limit value and the minimum limit value, when the environmental temperature rises, the cold air preventing temperature value rises synchronously; and when the environmental temperature declines, the cold air preventing temperature value declines synchronously; therefore, the control method can effectively improve the low-temperature heating amount. Under the control of the method, the heating amount at low temperature can be improved, and the blown air which is not over-cold can be ensured.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to cooling and heating type or pure heating household air conditioners, including a constant speed air conditioner and a speed-adjustable (frequency conversion) air conditioner, a control method for improving the comfort of the air outlet temperature, preventing cold wind from blowing out, improving The user's comfort is improved, the heating capacity at low temperature is improved, and the effect of fast and comfortable heating is achieved. Background technique [0002] Heating and heating type or pure heating household air conditioners, including fixed speed or speed adjustable (inverter type) air conditioners, when heating, if the indoor and outdoor temperatures are low and there is no anti-cold wind control, the temperature will be directly blown out at the beginning The wind will seriously affect the comfort of heating. The purpose of the anti-cold wind design is to keep...

Problems solved by technology

[0006] The third is that the whole process is designed with anti-cold wind, but the temperature value of the anti-cold wind is constant. The air conditioner controller compares the ambient temperature with the value of the anti-cold air temperature. When the anti-cold air temperature value is reached, the fan will turn from the stop state to the preset speed, so that the air conditioner will not blow out cold air, but when the outdoor temperature drops or frost forms, the temperature of the indoor heat exchanger will drop. If you do not refer to the ambient temperature , the indoor wind speed will be at a low wind speed, the heating effect will be greatly reduced, and the comfort of the human body will also be reduced. This method cannot adapt to the situation when the indoor temperature is low.
