What is the working principle of water chiller?

The working principle of water chiller is refrigerant (i.e. refrigerant) absorbed by cooling the heat and vaporize into steam in the evaporator, the compressor will continue to produce steam extracted from the evaporator, and compressed, compressed by high temperature, high pressure steam was sent to the condenser after to a cooling medium (such as water, air etc. exothermic) condenses into a high pressure liquid into the evaporator, the throttle step-down again after vaporization, absorb heat by cooling objects, so the cycle to cycle. When heating, the refrigerant changes the direction of the refrigerant flow through the four way valve, and the direction of the refrigerant flow is just the opposite of the refrigeration, the refrigerant passes through the evaporator, then returns to the condenser, and finally returns to the compressor.

How to pick up a suitable chiller?

First of all, it is necessary to find out which types of chillers you need,normally,there have  air cooled chiller and water cooled chiller

1.The air-cooled chiller, in which body containing a thermal insulation water tank and a water pump, without adding another cooling water tower to heat installation and removal is very convenient, but it is higher requirement of working environment, first, because it is a hot air circulating refrigeration, so if the installation workshop ventilation effect is not good, it will directly affect the cooling effect of cooling water machine. In addition, if you want to put the water cooler in a dust-free workshop with humidity requirements, it is recommended to refit the water-cooled one. Because the air-cooled chiller will eject steam from the top of the chiller to dissipate heat.

2.Water cooling machine can be divided into open type and sealed type (someone called it box type) and screw type, here we need to remind you that the water-cooled chiller is equipped with a cooling tower and water pump to remove heat from the water. To achieve a good cooling effect.

3.The open type cold water chiller,it shoud be installed a water tank ,but the sealed type do not have to install the water tank because it is built-in a water tank. Open type water chiller usually installed in the workshop somewhere, he convenient maintenance, but because not beautiful, so they have a water cooled type water sealing machine. Because it is a structure of the box, so popular.
