Embodiment Construction

[0056] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0057] Apparently, the illustrated embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0058] In order to facilitate understanding, in the present invention, it is necessary to elaborate on the technical problems therein.

[0059] When the air conditioner is in heating mode, the condenser of the outdoor unit needs to evaporate and absorb heat, and the outdoor ambient temperature that needs to be heated is low, so it is easy to cause the temperature outside the condenser to be too low and frost to form.

Abstract

The invention provides a non-stop defrosting control method and device and an air conditioner. The method comprises the steps that an outdoor environment temperature, an outdoor coil temperature and an outdoor condenser inlet pipe temperature are obtained in a heating mode of the air conditioner; according to the outdoor environment temperature, the outdoor coil pipe temperature and the outdoor condenser inlet pipe temperature, whether the air conditioner falls into a defrosting temperature range or not is judged; and if the air conditioner falls into the defrosting temperature range, an electromagnetic valve is controlled to be switched on. Therefore, when defrosting is needed, an air outlet of a compressor communicates with an air inlet of a condenser, a high-temperature and high-pressure refrigerant generated by the air outlet of the compressor is directly introduced into the condenser for defrosting, so that the purpose of defrosting can be achieved without switching the operationmode of the air conditioner, the situations that comfort is reduced and the experience feeling becomes bad due to operation mode switching are avoided, the normal operation state of the air conditioner is maintained, and the comfort and the experience feeling are improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a non-stop defrosting control method, device and air conditioner. Background technique [0002] When the air conditioner is in heating mode, the condenser of the outdoor unit needs to evaporate and absorb heat, and the outdoor ambient temperature that needs to be heated is low, so it is easy to cause the temperature outside the condenser to be too low and frost to form. [0003] Existing air conditioners usually switch from the heating mode to the cooling mode by switching the working state of the four-way valve after the condenser is frosted. In the cooling mode, the condenser of the outdoor unit condenses and releases heat, so that The frosting melts to achieve the defrosting effect. [0004] However, in this defrosting method, since the air conditioner is switched from the heating mode to the cooling mode, the indoor unit cannot continue to perform heating wo...
