What is heating and cooling air conditioning? Heating and cooling air conditioners are one of the essential electrical products in today's homes. Many families will choose this type of air conditioner, which can be warm in winter and cool in summer, which is very comfortable. Let's take a look at how to choose a heating and cooling model?
What is heating and cooling air conditioning
Air conditioners are divided into single cooling air conditioners and dual heating and cooling air conditioners. The working principles are the same. The refrigerant generally used in air conditioners is Freon. The characteristic of Freon is that when it changes from gaseous state to liquid state, it releases a lot of heat. When it changes from liquid to gas, it absorbs a lot of heat. Air conditioners are designed based on this principle.
The compressor compresses the gaseous refrigerant into a high-temperature and high-pressure liquid refrigerant, and then sends it to the condenser (outdoor unit) for heat dissipation to become a normal-temperature and high-pressure liquid refrigerant.
So the outdoor unit blows hot air.
Then it goes to the capillary tube and enters the evaporator (indoor unit). Since the space of the refrigerant from the capillary tube to the evaporator suddenly increases and the pressure decreases, the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, thereby absorbing a large amount of The evaporator will cool down due to the heat, and the fan of the indoor unit will blow the indoor air through the evaporator.
So the indoor unit blows out cold air; when the water vapor in the air encounters the cold evaporator, it condenses into water droplets and flows out along the water pipe. This is why the air conditioner produces water.
During heating, there is a component called a four-way valve, which causes the refrigerant to flow in the condenser and evaporator in the opposite direction to that during cooling. Therefore, during heating, cold air blows from the outside and hot air blows from the indoor unit.
Now that we have talked about what a heating and cooling air conditioner is, let’s talk about what you should pay attention to when buying a heating and cooling air conditioner.
When choosing, you need to pay attention to the size of the room.
Before users purchase a heating and cooling inverter air conditioner, they need to first determine the size of the room they will use, so that they can determine the number of air conditioners they need. Only by buying an air conditioner of the right size can you achieve good cooling and heating effects. There is a rough comparison table for what number of air conditioners correspond to what size of room. Users can also consult professionals.
Choose the applicable heating and cooling model
Common models on the market now include wall-mounted, cabinet-mounted, one-to-drag, ceiling-mounted, etc. Each model has different characteristics. When purchasing, it is best for consumers to choose according to the size of the room and air circulation conditions. Matching model and power. If the room area is more than 90 square meters, it is recommended to use central air conditioning. One-to-one is more energy-saving, and the ceiling-mounted type is more convenient and comfortable to use.
