Refrigeration units and chillers are two common types of refrigeration equipment, and there are some obvious differences in their functions, working principles, and application fields.
First of all, a refrigeration unit is a type of equipment used for refrigeration and freezing, and is commonly used in refrigeration, freezing, and refrigeration systems. It absorbs heat through the circulating flow of refrigerant and releases it into the external environment. Refrigeration units generally use components such as compressors and condensers to bring the target object or space to the desired low temperature by providing cryogenic coolant.
Whereas, chillers are mainly used to cool water to regulate and control the temperature. Chillers achieve temperature control through heat transfer between the refrigerant and cooling water. They typically consist of components such as compressors, condensers, evaporators, and circulating pumps. The working principle of the chiller is to use a circulating pump to pump the cooling water to the evaporator, and absorb heat through the evaporation of the coolant, so that the temperature of the cooling water is reduced.
Secondly, refrigeration units and chillers differ in their fields of application. Refrigeration units are widely used in food, pharmaceutical, chemical and other industries where low temperature environment is required. For example, cold storage, freezers, and frozen ice plants are typical application scenarios for refrigeration units. Chillers are mainly used in air conditioning systems, cooling equipment, processing equipment, etc. in industrial and commercial buildings.
In addition, chillers and chillers differ slightly in terms of operating temperature ranges, control methods, and performance requirements. Refrigeration units usually need to have strong refrigeration capacity, which can reduce the temperature to a lower range to meet the needs of refrigeration and freezing. Chillers, on the other hand, pay more attention to the control and stability of the cooling water, so that it can be kept constant within a certain temperature range. In addition, chillers are often equipped with a control system that is able to adjust the temperature and flow of the cooling water as needed.
To sum up, there are obvious differences between refrigeration units and chillers in terms of role, working principle and application field. Refrigeration units are mainly used in the field of refrigeration and freezing, whereas chillers are mainly used to provide cooling water and control and regulate temperature. For different needs and scenarios, choosing the right refrigeration equipment is the key to ensuring the proper operation of the system and achieving the desired results. Cold storage construction
