Contactez-nous dès aujourd'hui pour une solution parfaite de contrôle de la température

Cycle chillers are water cooling equipment that can provide constant temperature, constant flow, and constant pressure cooling water equipment. Using non-start-stop refrigeration technology, combined with PID temperature control, it has fast cooling and stable temperature, which is very suitable for some equipment that requires precise constant temperature cooling. The design and manufacturing of the equipment can provide excellent technical indicators and reliability in the industry, and it is a high-precision and highly stable cooling equipment. It provides models with different cooling outputs and is used in various laboratories and production fields to meet different cooling and constant temperature requirements. ​

How do cycle chillers work?

The equipment operates through three interrelated systems: refrigerant circulation system, water circulation system, and electrical automatic control system.

Cycle chillers first inject a certain amount of water into the water tank inside the machine, cool the water through the refrigeration system, and then send the low-temperature chilled water to the equipment that needs to be cooled by the water pump. The chilled water takes away the heat of the equipment that needs to be cooled and the temperature rises. Then it is sealed and returned to the water tank to achieve cooling effect. The cooling water temperature can be automatically adjusted according to requirements, which can save water for long-term use. Therefore, the chiller is a standard energy-saving and environmentally friendly equipment.

The composition of cycle chillers

(1) Condenser: During the refrigeration process, the condenser plays the role of outputting heat energy and condensing the refrigerant.

(2) Compressor: The compressor is the core component of the entire refrigeration system and the source of power for refrigerant compression. Its function is to convert the input electrical energy into mechanical energy and compress the refrigerant.

(3) Liquid receiver: The liquid receiver is installed after the condenser and is directly connected to the drain pipe of the condenser. The refrigerant liquid of the condenser should flow into the liquid receiver unobstructed, so that the cooling area of the condenser can be fully utilized.

(4) Thermal expansion valve: The thermal expansion valve is not only a flow regulating valve in the refrigeration system, but also a throttle valve in the refrigeration equipment. It is installed between the drying filter and the evaporator in the refrigeration equipment. Its temperature sensing The bag is wrapped around the outlet of the evaporator.

(5) Evaporator: The evaporator is a heat exchange device that relies on the evaporation of refrigerant liquid to absorb the heat of the cooled medium. Its function in a refrigeration system is to absorb heat. In order to ensure that the evaporation process can proceed stably and lastingly, the evaporated gas must be continuously pumped away by a refrigeration compressor to maintain a certain evaporation pressure.

(6) Electrical automatic control system: The electrical automatic control system includes the power supply part and the automatic control part. The power supply part supplies power to compressors, fans, water pumps, etc. through contactors. The automatic control part includes thermostat, pressure protection, delayer, relay, overload protection, etc., which are combined to achieve automatic start and stop, protection and other functions according to the water temperature.

(7) Refrigerant: Refrigeration is the flowing working fluid in the refrigerant refrigeration system. Its main function is to carry heat and absorb and release heat when the state changes.

(8) Drying filter: During the refrigeration cycle, moisture and dirt must be prevented from entering. The main source of moisture is the trace moisture contained in the newly added refrigerant and lubricating oil, or due to the entry of air during system maintenance. of moisture. If the water in the system is not completely removed, when the refrigerant passes through the throttle valve (thermal expansion valve or capillary tube), the water will sometimes solidify into ice due to the drop in pressure and temperature, blocking the passage and affecting the normal operation of the refrigeration device. Therefore, a filter drier must be installed in the refrigeration system.
