Air conditioner anti-cold-air control method and device as well as air conditioner

Abstract

The invention provides an air conditioner anti-cold-air control method and device as well as an air conditioner. A first indoor heat exchanger and a second indoor heat exchanger of the air conditionerare positioned at the same air outlet; a first expansion valve is arranged between the first indoor heat exchanger and the second indoor heat exchanger; and a second expansion valve is arranged between an outdoor heat exchanger and the first indoor heat exchanger. The air conditioner air-cold-air control method comprises the following steps of: under a refrigerating operation mode, acquiring indoor environment temperature information according to preset time interval; comparing the indoor environment temperature information with a preset expected temperature to obtain compared results; and according to the compared results, regulating a working state of the first expansion valve and a working state of the second expansion valve to control the first indoor heat exchanger to switch betweenan evaporating mode and a condensing mode. The switching process is flexible and quick, and the refrigerating effect and the air outlet temperature can be integrated very well, so that cold air formation is avoided, the cold air direct-blowing problem is completely solved, and extra problems such as condensation are not caused.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner anti-cold wind control method, device and air conditioner. Background technique [0002] Air-conditioning products can bring coolness to users in the hot summer, but users who have been in air-conditioned rooms for a long time are also vulnerable to colds. The fundamental reason is that after the indoor environment temperature reaches the set comfort zone, in order to keep the indoor temperature from rebounding, the air outlet temperature of the air conditioner will still remain low. At this time, the temperature difference between the inlet air temperature and the outlet air temperature is large, and cold air with a lower temperature will be formed. The cold wind blowing directly on the human body will cause the body temperature to be too low, which will cause discomfort to the user. [0003] At present, methods such as changing the direction of th...

Problems solved by technology

But in fact, due to the reflection of the wall and the different installation positions, it is often impossible to truly realize that the cold wind does not blow people.

In addition, if the wind direction is forcibly changed, the cooling effect will also be affected, and the hidden danger of condensation in the air conditioner will also be increased.
