The correct installation method for air-cooled chillers
Air-cooled chillers are no strangers to everyone, air-cooled chillers are divided into screw air-cooled chillers and scroll air-cooled chillers according to different compressors. When everyone buys a chiller, they will consider a problem chiller installation. Let's share with you the installation of air-cooled chillers. The condenser of the air-cooled chiller is finned type, and a heat dissipation fan is installed on the top of the unit, which directly dissipates heat through the fan to achieve the heat exchange effect. Relatively speaking, its installation is much simpler than that of water-cooled chillers, as long as the air-cooled chiller and the cooled equipment are connected through pipelines. The specific installer is as follows:
1. Before installation, to choose a flat open space, it is best to re-lay the cement foundation to ensure the horizontality of the ground, after the installation of the air-cooled chiller, there must be free space for future maintenance, and ensure that the ground can withstand the operating weight of the chiller. Different chiller models, the inlet and outlet pipe diameter is not the same, at the time of installation, to choose the water pipe that matches the pipe diameter, and connect it correctly.
2. No matter under any load situation, ensure that the water flow of the air-cooled chiller is normal and stable. The design and installation of all chilled water pipes should be carried out in accordance with relevant standards, and the water pump should be located on the inlet pipe of the unit to ensure the positive pressure and flow of the unit.
3. The pipeline should have a firm support independent of the chiller to avoid stress applied to the parts of the air-cooled chiller. In order to reduce noise and vibration, it is best to be able to install vibration isolators on the pipes.
4. In order to be able to safely and stably operate the air-cooled chiller and ensure the normal use of each component, the poor water quality can be treated to avoid all kinds of impurities or corrosive sediment and the presence in pipelines, evaporators and condensers that affect the heat exchange effect, and increase the maintenance costs in the later stage.
The working principle of a refrigerator
In the circulation system of the refrigerator, the compressor inhales low-temperature and low-pressure refrigerant steam from the evaporator, which is adiabatically compressed by the compressor into high-temperature and high-pressure superheated steam, and then pressed into the condenser for constant pressure cooling, and heat is released to the cooling medium, and then cooled into a supercooled liquid refrigerant.
