The application range of water-cooled chiller is relatively wide, and the price is relatively low compared with the air cooling machine, which is more suitable for customers with water.
The biggest difference between the air cooled and the water cooled is the water cooling tower, the water cooled is the use of water as a cooling medium, the heat is discharged through the cooling tower, which is suitable for occasions where a large amount of cooling water is needed, and the user who generally chooses the water cooled needs to place an order with the water cooling tower.
There are also types of air coolers, which are water coolers, screw water coolers and plate heat exchanger PHE water coolers.
Water-cooled chiller is the use of shell and tube evaporator to make water and refrigerant heat exchange, the refrigerant system absorbs the heat load in the water, so that the water cools down to produce cold water, through the compressor to bring the heat to the shell and tube condenser, by the refrigerant and water heat exchange, so that the water absorbs heat through the water pipe to take the heat out of the external cooling tower (belongs to water cooling).
Although the water-cooled chiller relies on a large amount of water to complete the cooling, but for environmental protection considerations, our products are made of sealed circulation of the pipeline, so that the water can be recycled and water resources can be saved.
Water-cooled chiller has certain requirements on the environment. It is recommended to provide a room for large water-cooled chiller to ensure the normal operation and service life of the equipment, including the chiller, chilled water circulating pump, and cooling water circulating pump. At the same time, cooling tower equipment is placed on the roof or outdoor floor of the building.
In terms of operating costs, water-cooled chillers can operate at lower condensing temperatures, and their cooling efficiency is higher and their power consumption is less. The total power consumption of the water-cooled chiller with the same cooling capacity is about 25% lower than that of the air-cooled unit.
In general, we recommend that customers with good water quality and suitable site conditions use water-cooled chiller, which can reduce costs while running stably.
Screw chiller named screw chiller because its key component – compressor adopts screw type.
The refrigeration principle of the screw chiller is that the refrigerant is converted into gas by the evaporator, compressed by the compressor, the compressed gas refrigerant waits for condensation in the condenser, after condensation, the refrigerant is converted into liquid, and becomes low pressure after the expansion valve, becoming a gas-liquid mixture, in which the liquid refrigerant under low temperature and low pressure absorbs the heat of the cooled substance in the evaporator. Back into a gaseous refrigerant. The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle.
The power of screw chiller is relatively large compared with the scroll type, and the price is relatively high, mainly used in central air conditioning systems or large-scale industrial refrigeration.
In addition to the air cooler can do plate change, water-cooled chiller can also do plate change, plate change relatively small area, plate heat exchanger structure is compact, unit volume heat exchange area is 2 to 5 times of the shell type, it is not like the shell type to reserve the maintenance site of the tube bundle, so achieve the same heat exchange, Plate heat exchanger covers an area of about one-fifth to one-eighth of the shell and tube heat exchanger.
Board change series chiller is a customized product, if necessary, we can provide customized services.
The above is the introduction of our water cooler, you can choose the products you want according to your own needs, our company will provide free machine consultation and one stop solution according to the customer's situation, installation program, welcome to consult at any time.
