Let's first understand what a chiller is. The chiller is commonly referred to as a chiller, a chiller, an chiller, a chiller, a chiller, etc. The nature of the chiller is a versatile machine that removes the liquid vaporizer through a compression or heat absorption refrigeration cycle.

The water-cooled chiller features: ergonomic panel, fully automatic control, equipped with precision electric temperature controller, which can run smoothly for a long time; adopts high-efficiency heat transfer heat exchanger, less loss of cooling capacity, easy oil return, heat transfer tube does not occur Frozen crack; imported high-performance compressor, high EER value, low noise, stable operation. Technically, water cooling is 300 to 500 kal/h higher than air cooling; in terms of price, water cooling is much higher than air cooling; in use, air cooling is due to fan cooling, ventilation, humidity, and temperature. (Can not be higher 40 ° C), the air pH value has a lot of requirements. Of course, on this basis, each (company) product has also been improved, for example: water-cooled screw chillers, selected original imported brand-name parts, using the latest technology for processing, so that the machine is stable, and further play out the parts The maximum efficiency, and in response to the call of the world's environmental protection organizations, led the creation of low-carbon energy-saving era.

If it is a chiller, it means a single-cooling unit. The heat pump unit is called a heat pump unit. It switches the direction of the refrigerant through a four-way reversing valve, and changes the order of the condenser and the evaporator to achieve the heating function. For example, in the summer cooling, the unit uses the air-cooled fin coil as a condenser and the shell-and-tube heat exchanger as an evaporator.

The water-cooled screw chiller is equipped with heat recovery. In the refrigeration project, the heat storage of the unit is added. Generally, the hotel uses more such equipment, so that it can be used for domestic hot water. The temperature control of the low temperature unit is generally between 0 and -100 degrees.
