Why can the cold king in Gree air conditioner only cool but not heat?

Let's see if there is a heating function first. If you buy a single-cooled air conditioner, you can't heat it. Single-cooling air conditioner, as its name implies, refers to an air conditioner with only refrigeration function. The corresponding heating and cooling air conditioner has two functions of cooling and heating, which can be used in summer and winter.

Single-cooling air conditioner only has refrigeration function. Considering energy saving and economy, areas with hot summer and warm winter, such as northern China, have heating systems, which can ensure sufficient indoor heating in winter, and the heating function of air conditioners is rarely used.

Heating and cooling air conditioning is more suitable for areas where Leng Xia is hot in winter. It is generally hot in summer and humid in winter in southern China, but there is no large-scale unified heating system in southern China as in the north, so it is more appropriate to choose cold and warm air conditioning. In order to ensure the heating effect, attention should be paid to heating capacity and cooling capacity when purchasing, and air conditioners with heating capacity greater than cooling capacity should be selected.

Discrimination of single cooling air conditioning

For general household air conditioners, the method of distinguishing single-cooling air conditioners from cold and warm air conditioners is very simple, just look at the model. The model label of domestic air conditioner is obvious. Usually, a single water chiller starts with "KF", cold and hot water chillers start with "KFR", and "KFRD" stands for cold and hot auxiliary heating.

However, the model labeling of joint venture air conditioners has its own characteristics and cannot be generalized uniformly. You can ask the promoters of the selected brand when purchasing.
