When the screw chiller is in use, its air-cooled condenser is fin type. It is mainly made of double oil corrugated hydrophilic aluminum platinum. It is manufactured by professional heat exchanger processing equipment and has compact structure and small volume. Light weight, high heat transfer efficiency, and low-speed large-leaf axial flow fan can effectively reduce operating noise and reduce the impact on the surrounding environment.
The unit control system of the screw chiller mainly adopts the imported PLC program controller, and the human-machine interface is equipped with a large screen touch screen. The interface is simple and generous, and the operation is intuitive and simple. The unit has reliable safety protection devices, including: high and low voltage protector, exhaust superheat protector, compressor motor overheat protector, overload current protector, antifreeze temperature protector, water flow protector, emergency stop switch, temperature sensitive Fused plugs, safety valves, etc.
Advantages of screw chiller
1. High efficiency and energy saving, the comprehensive energy efficiency ratio is up to 8.0, which can provide refrigeration, heating, and domestic hot water. It can automatically switch according to the ambient temperature and hot water demand, and make full use of energy.
2. When the hot water is used for cold recovery, it can realize zero cost of refrigeration.
3. Safe and environmentally friendly, with refrigerant as the medium, non-toxic, no explosion hazard, can be connected to the original hot water system, can replace the high-risk, high-cost boiler system, can also be used in conjunction with the solar system, replacing the electric heating part.
4. Fully automatic computer control, no need for special monitoring, can be operated by remote or centralized management system.
5. Unit type or modular type, assembled structure, compact size, flexible installation on the roof, terrace or machine room.
6. The cold air discharged during hot water can be used to reduce the ambient temperature and improve the environmental quality.
The screw chiller mainly uses its horizontal shell-and-tube condenser and shell-and-tube evaporator in operation. It has the characteristics of simple structure, stable heat exchange, long-lasting efficiency and convenient maintenance. It has been recognized as the central air-conditioning main unit. The ideal structural composition.
