Refrigeration compressor: what you need to know before buying equipment
Before you buy a refrigeration compressor https ://energoholod.com.ua/ru/kompressory/kompressory-torgovogo-holodilnogo-oborudovaniya/, read the characteristics of the equipment. This device is responsible for compressing and transferring refrigerant vapor in various refrigeration systems. Such units are most often found in air conditioners and industrial installations. These can be freezers for use in the food, medical, chemical, pharmaceutical industries and so on. According to a number of characteristics, the industrial refrigeration compressor is divided into several varieties.
Varieties of industrial refrigeration compressors
There are several groups in this category.
-
Reciprocating compressor - compresses gas with a piston.
-
The rotary refrigeration compressor drives the rotor - thanks to this part, the pressure increases.
-
Centrifugal compressors in refrigeration units work by compressing gas under centrifugal force.
Also, units for refrigerating chambers can be of an open type - the electric motor is outside the housing. It is connected to the compressor directly or through the transmission. Closed type compressors are located in containers, in the same place as the motor.
What determines the choice of a refrigeration compressor
The choice primarily depends on the purpose of the application. In freezers with high performance, as well as where several units are installed at the same time, devices with a circulation system provided by a pump are used. This results in good heat dissipation. Recirculation with a pump ensures simultaneous freezing in the entire freezer.
In secondary systems, solutions of chlorine or trichlorethylene are most often used as coolants. This type requires quite large financial costs, so its use is limited.
A compressor equipped with gravity circulation will freeze products efficiently and quickly. It is used for individual freezers of medium and large capacity. The internal receiver can be installed directly on the freezer. Before you buy a refrigeration compressor, you need to calculate the parameters of the unit so that the refrigeration unit matches the production capacity.
What you need to know before buying a refrigeration compressor
There are different brands and models on sale. The main purchase criteria are factors such as price, scope, capacity and maintenance.
-
The price of a domestically produced refrigeration compressor is much lower, so this unit is the preferred choice for most small and medium-sized enterprises.
-
Calculate the operating power of the refrigeration compressor. A powerful device in a small production will lead to energy loss and additional costs.
-
Oil-free refrigeration compressors are much more expensive than conventional units of the same capacity. They are commonly used in food processing, medicine, precision instruments and so on. Variable frequency refrigeration compressors are also more expensive than other units because they are more efficient.
When choosing, you also need to take into account post-warranty service. Find out if replacement parts are easy to find if your equipment needs to be repaired.
