Chiller component structure and composition

There are four main components that constitute the basic refrigeration system of a chiller: compressor, evaporator, condenser, and throttle valve. In addition, there are many auxiliary devices: liquid pipeline solenoid valves, sight glasses, liquid pipeline drying filters, high and low pressure controllers, etc.

Working principle of chiller:

The chiller compresses the refrigerant into a liquid state through the compressor and sends it to the evaporator for heat exchange with the chilled water to cool the chilled water. The freezing pump sends the chilled water to the cooling coil at each fan outlet, and is blown by the fan to achieve cooling. Purpose. The evaporated refrigerant releases heat in the condenser and turns into a gaseous state. The cooling pump sends the cooling water to the cooling tower. The water tower fan sprays and cools it. It exchanges heat with the atmosphere and dissipates the heat into the atmosphere.

1. Chiller

This is the “heart” of the refrigeration system. The circulating water leading to each room is “internally exchanged” by the chiller and cooled down into “cooling water”.

2. External heat exchange system

Two circulating water systems: The chilled water circulation system consists of freezing pumps and chilled water pipelines. The chilled water flowing out from the chiller is pressurized by the freezing pump and sent to the chilled water pipes, where heat exchange occurs in each room, taking away the heat in the room and causing the temperature in the room to drop.

Cooling water circulation system: consists of cooling pumps, cooling water pipes and cooling towers. The chiller performs heat exchange and will release a large amount of heat while cooling the water temperature. This heat is absorbed by the cooling water, causing the temperature of the cooling water to rise. The cooling pump presses the heated cooling water into the cooling tower, allowing it to exchange heat with the atmosphere in the cooling tower, and then the cooled cooling water is returned to the chiller. This continuous cycle takes away the heat released by the chiller.

3. Cooling fan

Indoor fan: Installed in the room that needs to be cooled, it is used to blow the air cooled by the chilled water into the room to accelerate the heat exchange in the room.

Cooling tower fan: used to reduce the water temperature of the cooling tower and accelerate the dissipation of the heat brought back by the “return water” to the atmosphere.
