Anonymous users2024-01-24The main components of all three things are heat exchangers and fans. The heat exchange medium is liquid, which exchanges cold and heat with the indoor air.
The fan coil unit and the ceiling air conditioner heat exchanger flow water, which is supplied by the refrigeration station (boiler room); Chilled water in summer and hot water in winter; The ceiling air conditioner can also be regarded as a large fan coil unit, with a larger circulating air volume and a larger heat exchanger area.
The refrigerant flows in the heat exchanger of the pipe machine, and the refrigerant is supplied by the outdoor unit of the air-cooled heat pump. In summer, the refrigerant liquid supplied to low temperature and low pressure is absorbed and evaporated in the heat exchanger, and then returned to the compressor of the outdoor unit for recompression after being converted into low temperature and low pressure vapor; In winter, the refrigerant vapor supplied to high temperature and high pressure is dissipated in the heat exchanger and becomes a high temperature and high pressure refrigerant liquid, and then returns to the outdoor unit, and then returns to the compressor for recompression after heat absorption vaporization in the evaporator. That is, the heat exchanger of the indoor unit of the air-cooled heat pump pipe machine is the evaporator in summer and the condenser in winter, and the heat exchanger of the outdoor unit is the condenser in summer and the evaporator in winter.

Anonymous users2024-01-23The fan coil unit is just a heat exchange and air supply equipment, and it cannot work without a cold and heat source.
Air conditioners have a heat source and come with their own air supply equipment, which is usually installed on the roof.
The difference between a duct machine and an air conditioner is that the installation method is different, and the air supply method is different.
1. In the production process of the factory, the hydrostatic test is a sampling inspection and type test project, and not every unit is done; >>>More
Ceiling air conditioning:
There are several forms of existence, such as the four-sided air outlet type (also called the card type), the air outlet type on one side of the ceiling, and the air supply type of the ceiling air duct; >>>More
Not quite consistently. Horizontal fan coil unit generally refers to the concealed, connected back style grid, hanging type. The ceiling-type fan coil unit has four air outlets (also called card type) and a ceiling surface-mounted.
The sound is loud to see whether the sound is only the wind sound, if there is no abnormal sound should be normal, check whether the filter is blocked, if it is a fan, it will be more difficult.
The data given shows that the correspondence between air volume and cooling capacity is poor; >>>More
