Cold storage refrigeration equipment price according to the refrigeration characteristics of the decision
Summer is coming soon, and the temperature will be higher and higher. At this time, whether it is a chilled watermelon or a variety of flavors of Popsicle, it is a good thing for people to relieve the summer. And these things want to have a suitable temperature, you need to use the semi-closed refrigeration compressor, the general refrigerator cold storage will be used in the semi-closed refrigeration compressor, the main way of refrigeration there are two kinds:
1. Compression refrigeration
1) Screw refrigerator: simple structure, less wearing parts, long service life, high single-stage compression ratio, in the range of large and medium-sized refrigerating capacity there is a trend to replace the piston type.
2) Piston refrigerator: The technology development is mature, high efficiency, wide range of temperature, can be made into large, small, medium and various specifications of products, is widely used in a variety of refrigeration machines.
3) Centrifugal refrigerator: The use of high-speed rotating impeller to obtain kinetic energy of refrigerant gas, and then through the diffuser to improve its pressure and cooling liquefaction, throttling and refrigeration. It has the advantages of compact structure, large cooling capacity and energy adjustment. R11 and R12 refrigerants are used in air conditioning machines.
2. Absorption refrigeration
The absorption of refrigerant by an absorber is used to vaporize refrigerant and refrigerate it. Commonly used ammonia - water absorption refrigerating machine and lithium bromide - water absorption refrigerating machine, using heat source as power, less power consumption, stable operation, less wearing parts, large range of energy regulation, is a new development of refrigerating machine varieties.
Two refrigeration methods are also have their own advantages, consumers in the choice of time can choose according to their own needs, one is to see the power consumption, the other is to see the refrigeration range and effect, if the place is smaller then choose compression refrigeration can be
