Chiller refrigeration principle

Release time: 2019-06-24 14:30:39

Cooling equipment such as chillers are commonly used in factories in today's industrial era. Some equipment must have cooling equipment, and some equipment can not be cooled or let it cool naturally. For production efficiency and product quality, it is more efficient and fast. In the era of rhythmic flow, industrial chillers have become an inevitable choice. When the user's new equipment comes online, the cooling plan is often put on the agenda, and even the new equipment production line is included in the plan at the same time. At this time, many users of industrial chiller for the first time will want to understand the cooling principle and cooling process of industrial chiller, so as to facilitate the integration of installation and operation methods in the design and daily use.

Anshijia Machinery will elaborate on the refrigeration principle and cooling process of industrial chiller for everyone today.

Industrial chiller refrigeration is a process that uses a compressor to compress the refrigerant to circulate it; the compressor rotates and uses the refrigerant to pressurize the refrigerant into high-temperature and high-pressure gas; the high-temperature and high-pressure gas passes through the condenser through a fan (air-cooled chiller) Or the cooling tower (water-cooled chiller) is cooled to a medium-temperature and high-pressure liquid state. The medium-temperature and high-pressure gas enters the evaporator through the shut-off valve, and the intercepted and expanded refrigerant immediately vaporizes into a gas. The vaporization process will absorb a large amount of heat. This heat comes from the tap water in the water tank, and the tap water exchanges heat with the evaporator to achieve the purpose of cooling.

According to the law of conservation of energy, the heat of the compressor's exhaust gas is equal to the cooling capacity, but since the motor power is also converted into a part of the heat in this process, the heat of the exhaust gas is actually greater than the cooling capacity by about 20-30%; Consider this. Both the air-cooled cooling air volume and the water-cooled cooling water volume are based on the power of the compressor discharge volume.

Factors to consider:

1. Is there any space limitation at the installation site? The air-cooled type is not suitable for indoor installation. The water-cooled type requires the cooling tower to be installed outdoors.

2. Ambient temperature and air quality in the area, and water quality.
