What central air conditioning system does the hotel usually use?

The central air conditioning systems commonly used in hotels include fixed frequency multi-connection, variable frequency multi-connection, air duct unit and air cooling module unit.

* Fixed frequency multi-access: commonly known as VRV system, commonly known as "one delay and more". The main engine of the system is directly connected with the indoor unit, with refrigerant as the main heat exchange medium. Indoor pipes are all copper pipes, and all pipes are refrigerants. The cooling speed of this system is relatively fast, and each room can be controlled independently, so the temperature control is very accurate.

* Frequency conversion multi-connection: that is, VRV system, commonly known as "one drag and more". Compared with the fixed-frequency multi-connection system, the main feature of the variable-frequency multi-connection system is that it uses a variable-frequency compressor and connects multiple indoor units with branch pipes.

* Air duct unit: the air conditioner is connected with the air duct to supply air to the room. The so-called high static pressure air duct machine means that the fan used in air duct air conditioning is a high static pressure fan, and the static pressure of air conditioning is equivalent to the residual pressure outside the machine, which is a parameter of air supply capacity of air conditioning. The greater the static pressure, the longer the gas supply lifting time. Because the air supply of duct air conditioning needs to pass through the duct, the wind pressure loss will increase during the air supply process. If you don't use a high static pressure fan, there will be little air sent into the room.

* Air-cooled module central air-conditioning system: it is an integrated central air-conditioning equipment with air as cold (hot) medium and cold (hot) source. Because the air-cooled modular unit needs to pass through the air duct, the air pressure loss will increase during the air supply process. If you don't use a high static pressure fan, there will be little air sent into the room.

When choosing the central air-conditioning system of the hotel, we should choose the appropriate air-conditioning system according to the actual situation and needs of the hotel.
