What is the standard of commercial air conditioning? Classification introduction of commercial central air conditioning
With the economic development in China, many families have gradually stepped into a well-off life, and more and more families have gradually started to buy high-tech household items for their families. Now the most popular household items are air conditioners, refrigerators and so on.
1. What is a commercial air conditioner?
Commercial air conditioners have a history of one hundred years in the world and more than 20 years in China. However, these years have really attracted the attention of domestic enterprises. At present, the competition in the domestic air-conditioning field has entered a white-hot stage. With the continuation of the price war, almost unprofitable enterprises in the domestic air-conditioning field began to look for new development space and profit growth points in the central air-conditioning field.
Second, the classification of commercial central air conditioning
Commercial central air conditioning is mainly composed of refrigerator, cooling water circulation system, chilled water circulation system, fan coil system and cooling water tower. The refrigerator compresses the refrigerant into a liquid state through a compressor, and then sends it to an evaporator for heat exchange with frozen water, thereby refrigerating the frozen water. Chilled water is sent by chilled water pump to cooling coils at the air outlets of fans, and cold air is blown by fans to achieve the purpose of cooling. The evaporated refrigerant releases heat in the condenser and exchanges heat with the cooling circulating water. The cooling water pump pumps the cooling water that brings heat to the cooling water tower, and the fan of the cooling water tower sprays it for cooling, and exchanges heat with the atmosphere to dissipate heat into the atmosphere. According to the system classification, it can be divided into two categories: cold water system and refrigerant system.
1, classification of commercial central air conditioning-cold water system
The cold water system of commercial central air conditioning is usually called cold (hot) water unit, and the indoor load is borne by the cold and hot water unit. The fan-coil unit in each room is connected with the cold and hot water unit through pipes, and indoor refrigeration and heating are provided by the provided cold and hot water. The water system has flexible layout, good independent regulation and very high comfort, which can meet the needs of scattered use of complex rooms and independent operation of each room. It can be subdivided into:
● Air-cooled cold water central air conditioning
● Air-cooled modular central air conditioning unit
● Air-cooled screw central air conditioning unit
● Air-cooled centrifugal cold and hot water central air conditioning unit
● Water-cooled scroll central air conditioner
● Water-cooled screw central air conditioner
● Water-cooled centrifugal central air conditioning
● Water/ground source heat pump central air conditioning
2. Classification of Commercial Central Air Conditioning-Refrigerant System
The refrigerant system of commercial central air conditioning is fluorine-based central air conditioning, which is a frozen dosage air conditioning system using transport refrigeration technology. The temperature of multiple rooms can be adjusted at the same time; In addition, the frequency conversion compressor of the outdoor unit of fluorine system can automatically adjust the working state of the compressor according to the change of indoor cold and heat load to meet the requirements of indoor cold and heat load, and can accurately control the temperature and save electricity. There are two types: single machine and multi-machine
● The unit is central air-conditioned with a trailer. The outdoor unit is connected with the indoor unit, which is divided into ceiling embedded central air conditioner, duct central air conditioner and large air volume cabinet air conditioner.
● Multi-connection and multi-connection, commonly known as "one drag and multi-connection", means that an outdoor unit is connected with two or more indoor units through pipelines, and the outdoor side carries out air-cooled heat exchange, and the indoor side carries out direct evaporation heat exchange.
Third, commercial air conditioning standards
According to international standards, commercial air conditioners are collectively referred to as air conditioning units above 3HP, so there are many types of commercial air conditioners. ? Including air-cooled heat pump central air conditioning unit, water-cooled screw chiller, centrifugal chiller, etc.
Through the above introduction to the classification and standards of commercial air conditioners, I hope it will be helpful for you to buy air conditioners in your life. Want to know more about the price of commercial air conditioners, you can pay attention to Tuba Rabbit, so stay tuned!
