Chiller
Chiller and freezer are common industrial refrigeration equipment today, the two principles of operation, structural construction, etc. are very similar, in actual use, most of the two scenes are only called, called different. If you want to distinguish from the details, there are the following three points:
1, chiller units include water-cooled, air-cooled, heat pump unit type, etc., in addition to the core cooling function, you can also heat, and large air-conditioning unit with a function similar to the chiller unit is mainly refrigeration, does not have the function of heating.
2, chiller and freezer unit cooling range is different, freezers usually provide low-temperature cold source, water chillers have room temperature type and low temperature type. Chillers usually use different refrigerant can be obtained room temperature type, low temperature type of chiller, the use of cooling water to dissipate heat can be; and freezer because the cold source is usually provided for the sub-zero, so the cooling medium needs to use brine or glycol carrier cooling to dissipate heat.
3, the freezer usually need to add oil separator, to prevent the low temperature brought about by the difficulty of oil return; chiller room temperature type generally do not add oil separator, low-temperature type according to the needs of the increase in oil separator.
In the actual application, the difference between the chiller and freezer is not big, the two are basically just called on the different, many times the freezer and chiller is the same equipment is called differently, only to some of the needs are not the same, only to carry out some of the functions of customization and design, such as large-scale frozen warehouses, supermarkets, food, fresh vegetables, such as preservation of the use of freezers is more appropriate, while the demand for 5 ℃ to 40 ℃ to 40 ℃, the use of freezer, the use of freezers, the use of freezers, and the use of freezers. Demand for 5 ℃ to 40 ℃ temperature control range, the use of chiller is more economical.
