Water Cooled Screw Chiller Load Requirements
- Sep 28, 2017 -

Unit cooling, the compressor will evaporator low temperature and low pressure refrigerant into the cylinder, Water Cooled Screw Chiller through the compressor work, refrigerant vapor is compressed into high temperature and high pressure gas,

Through the exhaust pipe into the condenser. High temperature and high pressure refrigerant gas in the condenser with the cooling water for heat exchange, Water Cooled Screw Chiller the heat transfer to the cooling water away, while the refrigerant gas is condensed into high pressure liquid. The high pressure liquid from the condenser is throttled by the thermostatic expansion valve and enters the evaporator. In the evaporator, Water Cooled Screw Chiller the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes the chilled water to cool down and becomes the desired low-temperature water. Water Cooled Screw Chiller The vaporized refrigerant gas is re-sucked by the compressor and discharged into the condenser, so that it is circulated again and again, thereby cooling the chilled water.

From the unit out of chilled water, into the indoor fan coil, variable air volume air conditioner and other end devices in the indoor and convective air heat exchange, Water Cooled Screw Chiller in the process, the water due to the absorption of indoor air heat (to the indoor air heat) And the temperature rises, and the indoor air through the indoor heat exchanger after the temperature drop, Water Cooled Screw Chiller driven by the fan, into the room, thereby reducing the indoor air temperature, and the temperature rise after the chilled water in the pump under the re-enter the unit, so Cycle, so as to achieve the purpose of continuous cooling.

Single-screw water-cooled chillers refrigeration systems include refrigeration cycle main system and jet cooling auxiliary system. The unit cooling system and the unit water system form a centralized air conditioning cold water system to meet the different load requirements. The unit water system includes a cooling water system and a chilled water system, which is owned by the user unit or the construction unit. Water Cooled Screw Chiller The spray cooling assist system is used to cool the compressor. Refrigeration cycle main system: the compressor inhalation evaporator in the low-temperature low-pressure refrigerant gas, after compression into a high temperature and high pressure gas and put into the shell and tube water-cooled condenser; in the condenser, Water Cooled Screw Chiller high temperature and high pressure refrigerant gas And heat exchange with cooling water,

Condensed into a room temperature and high pressure refrigerant liquid, Water Cooled Screw Chiller the cooling water after the cooling water pump is transported to the cooling tower by air cooling and recycling. The refrigerant liquid with a certain degree of subcooling is cooled by the thermal filter and the electromagnetic valve through the thermal expansion valve, and then enters the shell-and-tube water-cooled evaporator. In the evaporator, the low-temperature and low-pressure refrigerant liquid is heated with the chilled water Exchange, absorb the heat of chilled water after a certain degree of superheat to become low-temperature low-pressure refrigerant gas, and then by the compressor suction compression, began a new cycle. In this way, Water Cooled Screw Chiller the chilled water through the evaporator is cooled, cooled and passed through the chilled water pump to the end device heat exchanger, and heat exchange with the indoor air to continuously deliver cold air.

Single screw type water-cooled chillers adopt superposition type combination structure,Water Cooled Screw Chiller including single screw compressor, shell and tube condenser and evaporator, electrical control system, refrigerant jet cooling system, piping system, filtration and lubrication system. The unit has been filled with refrigerant and lubricants.
