Abstract

The invention relates to a sterilization control method for a single-cold-type air conditioning unit. The method comprises the steps that a sterilization control instruction is received, according to the sterilization control instruction, a first electric valve is closed, the flow direction of a condensing agent from a compressor to a condenser is cut off, and a second electric valve is opened, so that the flow direction of the condensing agent is adjusted to be a path from the compressor to an evaporator through the second electric valve. According to the scheme, due to the fact that the first electric valve and the second electric valve are arranged on an air conditioner refrigeration loop, the flow direction of the condensing agent is changed by controlling the closing state of the first electric valve and the closing state of the second electric valve, the sterilization function of the single-cold-type air conditioner unit is achieved, and a single-cold-type air conditioner has the heating and self-cleaning effects.

Description

technical field [0001] The present application relates to the technical field of air conditioning, and in particular to a sterilization control method for a cooling-only air-conditioning unit and the air-conditioning unit. Background technique [0002] Most of the existing heat pump air conditioners have a self-cleaning mode. The principle is to make the evaporator frost in the cooling mode through the air conditioner, and then defrost in the heating mode, and the frost will form water to take away the dirt to achieve the purpose of cleaning. However, the existing cooling-only air-conditioning unit can only perform cooling of the indoor unit because it cannot reverse the flow direction of the condensing agent, and cannot perform thermal sterilization of the indoor unit. Contents of the invention [0003] In order to overcome the problems existing in the related technologies, the present application provides a sterilization control method of the cooling-only air-conditionin...
