LIRUISI Row-Level Air-Cooled Machine Room Precision Air Conditioner CRA3050
Product introduction:
LRS-CRA series row-level air-cooled room air conditioner is a temperature control product specially designed for medium and high heat density data centers, which is installed close to the heat source, shortens the cold air flow path, and accurately processes the sensible heat generated by the server, which is an ideal choice for green energy-saving data centers and various electronic equipment rooms.Application scenarios: small and medium-sized data centers, modular data centers, cabinet cooling (hot) channel transformation, medium and high heat density communication equipment and computer rooms, etc.
LIRUISI room-level air-cooled precision air conditioning CRA3050 is an air conditioning system that controls the temperature, humidity, and air flow rate of the data center through compression refrigeration.
Its working principle is as follows:
1. Refrigeration cycle: The refrigeration cycle is achieved by evaporating and condensing the refrigerant to absorb and release heat, in order to lower the temperature of the data center. Specifically, indoor air is drawn into the air conditioning system, treated through filters and humidifiers, and then enters the evaporator, where it exchanges heat with the refrigerant. At the same time, the moisture in the air is absorbed, reducing the air temperature and relative humidity. After evaporation, the refrigerant is compressed and enters the condenser, where it exchanges heat with outdoor air (or cooling water), releasing heat and returning the refrigerant to its liquid state.
2. Control system: The control system detects the state of the data center, including temperature, humidity, and air flow rate, through sensors. These signals are transmitted to the controller, which then controls the system based on set values. By precisely adjusting the speed of the compressor, fan, and valve opening and closing, stable control of the data center temperature, humidity, and air flow rate can be achieved.
3. Heat dissipation system: The heat dissipation system mainly uses pipes, radiators, and fans to discharge the heat from the evaporator and condenser. Specifically, the condenser releases heat through cooling water or air, while the evaporator releases heat by discharging outdoor air or a drainage pipe.
