Abstract

The invention discloses an air conditioner and a low-temperature cooling control method and device of the air conditioner. The low-temperature cooling control method of the air conditioner includes the following steps: detecting the current temperature of the outdoor environment; judging a temperature interval to which the current temperature of the outdoor environment belongs, wherein the temperature of the outdoor environment is divided into a plurality of temperature intervals, and each temperature interval corresponds to one draught fan rotating speed; controlling the air conditioner to run in the cooling mode, and controlling an outdoor draught fan of the air conditioner to run at the draught fan rotating speed corresponding to the temperature interval to which the current temperature of the outdoor environment belongs. In this way, the cooling requirement of a user in the low-temperature environment can be met; for example, the air conditioner can normally carry out cooling at the temperature ranging from -15 DEG C to 20 DEG C, and the requirement that 100% of the cooling capacity is output can be met.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a low-temperature refrigeration control method for an air conditioner, a low-temperature refrigeration control device for an air conditioner, and an air conditioner. Background technique [0002] With the increasing number of people using air conditioners, users have higher and higher expectations for the use of air conditioners. The indoor temperature will rise due to the heat generated by the indoor human body, lighting fixtures, electrical equipment and gas appliances, and the heat insulation effect of modern architectural design materials is good, and the heat leakage is small. In the range of 0°C, there is still a need for indoor cooling, especially in crowded places, such as conference rooms, dance halls, passenger stations, kitchens and other places where there is a lot of people and a lot of exercise. The indoor temperature is often higher than the outdoor l...
