Abstract

The invention relates to a floor heating unit which comprises at least two air conditioner modules and at least one floor heating module. When the outdoor environment temperature belongs to a first temperature interval, all the air conditioner modules operate in a heating mode; when the outdoor environment temperature belongs to a second temperature interval, at most n-1 groups of air conditioner modules are controlled to operate in a heating mode, at least one group of air conditioner modules are controlled to stop, and when the air conditioner modules need to be defrosted, the stopped air conditioner modules are controlled to operate in a heating mode, reduced heat of the defrosted air conditioner modules is supplemented, and comfort of the indoor temperature is guaranteed; and when the outdoor environment temperature belongs to a third temperature interval, part of the air conditioner modules are controlled to operate in a heating mode, the other part of the air conditioner modules are stopped, and when the air conditioner modules need to be defrosted, all the air conditioner modules operating in the heating mode are controlled to defrost, and all the stopped air conditioner modules are controlled to heat. The situation that enough air conditioner modules are in heating operation is ensured, the water temperature is kept stable, the situation that the indoor temperature is stable and comfortable is ensured, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a floor heating unit. Background technique [0002] For air-cooled air-conditioning units, when heating in winter, water vapor in the air will gradually condense on the surface of the outdoor heat exchanger during the process of heat absorption by the heat pump, and a thick layer will form on the surface of the heat exchanger after a long time. Thick hoarfrost seriously affects the heat exchange effect of the heat exchanger, thereby greatly reducing the heating capacity of the heat pump. Moreover, after frosting, the outdoor heat exchanger has poor heat exchange for a long time, which can easily damage the key components of the air conditioner. [0003] In order to ensure the heat exchange efficiency of the outdoor heat exchanger and the reliability of the heat pump of the air conditioning unit, the current main solution is to stop the compressor, switch the four-way va...
