Embodiment Construction

[0042] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] figure 2 It is a flow chart of an air conditioner uninterrupted heating defrosting control method provided by the present invention.

[0044] see figure 2 , the present invention provides a method for controlling uninterrupted heating and defrosting of an air conditioner, comprising the following steps:

[0045] Step S201: air conditioner heating operation;

[0046] Step S202: Make a defrosting judgment, judge whether the heating time is ≥ 45 minutes, and the temperature difference between the outdoor heat exchanger coil temperature and the outdoor air is ≥ 9 degrees; if yes, enter step S203, if no, return to step S201;

[0047] In view of the fact that after heating for a period of time, the outdoor heat exchanger (that is, the ou...

Abstract

The invention discloses an air-conditioner continuous heat-supply and defrost control method, based on an original four-way valve defrost control logic, control logics of hot air bypassing and an induced electricity heater are added in the method, when the defrosting is carried out in winter, the heat quantity can be supplied continuously to a room to ensure the comfortableness of the indoor environment, part of judgment conditions of the original control logic are modified, the begin and the end of the defrosting can be accurately judged and the systematic defrosting and heating can be effectively carried out, thereby greatly increasing the using comfortableness of air-conditioner users, enhancing the product using feelings of users, increasing the reliability of the air-conditioner system and having wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method for uninterrupted heating and defrosting of an air conditioner. Background technique [0002] An air conditioner is an electrical device that regulates and maintains the indoor temperature at the condition required by the user. The air conditioning function of the air conditioner is completed by the refrigeration circulation system and the air circulation system. The refrigerant circulating in the refrigeration system exchanges heat with the air flowing in the room to achieve indoor cooling or heating, and provide people with fresh and comfortable air. indoor air environment. [0003] The refrigerating cycle system of the air conditioner includes a heat exchanger, a compressor and throttling devices. The air circulation system includes a fan and a fan motor, an air inlet and outlet and an air filter. The operation of the refrigeration cycle system and...
