High sensible heat
The host and peripherals, servers, switches, optical transceivers and other computer equipment installed in the computer room, as well as power support equipment, such as UPS power supply, will dissipate heat into the computer room by means of heat transfer, convection, and radiation. These heat only cause the temperature in the computer room. The increase is sensible heat. The heat dissipation of a server cabinet ranges from a few kilowatts to a dozen kilowatts per hour. If a blade server is installed, the heat dissipation will be higher. The heat dissipation of large and medium-sized computer room equipment is about 400W/m2, and the data center with higher installed density may reach more than 600W/m2. The sensible heat ratio in the computer room can be as high as 95%.

Low latent heat
It does not change the temperature in the computer room, but only changes the moisture content of the air in the computer room. This part of the heat is called latent heat. There is no humidity dissipation device in the computer room, and the latent heat mainly comes from the staff and the outdoor air, while the large and medium-sized computer room generally adopts the management mode of man-machine separation. Therefore, the latent heat in the engine room is small.

Uninterrupted operation, year-round cooling
The heat dissipation of the equipment in the computer room is a steady heat source and operates uninterrupted throughout the year. This requires a set of uninterrupted air conditioning guarantee system, and there are also high requirements on the power supply of the air conditioning equipment. And for the air-conditioning system that protects important computer equipment, there should also be a generator set as a backup power supply. The long-term steady-state heat source causes the need for cooling even in winter, especially in the southern region. In the northern region, if cooling is still required in winter, the condensing pressure of the unit and other related issues need to be considered when selecting an air-conditioning unit. In addition, the proportion of outdoor cold air intake can be increased to achieve the purpose of energy saving.
