Unit air conditioner

Right!

The unit type air conditioner refers to a split type wall-mounted and cabinet air conditioner, which is a product composed of several units.

When the air conditioner is used for cooling operation, the low-temperature and low-pressure refrigerant gas is sucked into the compressor and pressurized to become a high-temperature and high-pressure refrigerant gas. It becomes a medium-temperature and high-pressure liquid (the heat is taken away by the outdoor circulating air), and the medium-temperature and high-pressure liquid is throttled and reduced by the throttling component to become a low-temperature and low-pressure liquid. After evaporation, it becomes medium-high-temperature and low-pressure gas (the indoor air is cooled down to reduce the temperature of the room through the surface of the heat exchanger), and the low-temperature and low-pressure refrigerant gas is sucked into the compressor and circulated.

Room air conditioners are generally unit air conditioners, (integrated window air conditioners are also unit type).

Split-type wall-mounted and cabinet-type air conditioners are collectively referred to as unit air conditioners (it is a product composed of several units).

The central air conditioner is an air conditioner that controls the different rooms to achieve the purpose of indoor air conditioning by means of a host passing through the air duct or connecting multiple ends of hot and cold water pipes. Adopting the duct air supply method, one host can control multiple different rooms and introduce fresh air, which can effectively improve the indoor air quality and prevent the occurrence of air-conditioning diseases. The most prominent feature of home central air-conditioning is to produce a comfortable living environment. Secondly, from the perspective of aesthetics and the best use of space, the use of home central air-conditioning makes the interior layout more flexible.
