Some Advice When Buying A Chiller?


The chiller is a kind of refrigeration equipment that can provide industrial chilled water to various industries to achieve the purpose of cooling. According to the cooling method, it can be divided into air-cooled chiller and water-cooled chiller, which can control the temperature to 3 to 35 degrees. In addition, the low temperature chiller can control the temperature between 0 and -40 degrees. When selecting a chiller, we need to know exactly how much the inlet water temperature of the chiller, the temperature of the outlet water, the flow rate, the size of the water tank, etc., and the operating environment of the chiller, such as the ambient temperature, the ambient temperature season, Change, environmental space, etc. The following are some suggestions from Anyda refrigeration. After all, a cheap and inexpensive chiller is not only a guarantee of successful engineering design, but also has a long-term impact on the operation of the system:

 

1. Cooling water flow: refers to the cooling water circulation flow of the chiller that needs to be supplied when the refrigeration equipment is in use;

 

2, cooling capacity: that is, how much cooling capacity;

 

3, the water temperature, backwater temperature or return water temperature difference requirements: the water temperature is the required temperature of the chilled water, water temperature refers to the cooling water temperature, some cooling requirements are more stringent equipment will have cooling water supply temperature requirements;

 

4. Outgoing water pressure: Some of the required cooling equipments have a certain pressure requirement for the cooling water supply due to the complex internal cooling structure of the equipment. In this case, it is necessary to consider whether the rated water pressure of the chiller can meet the requirement.

 

5, the pump head: If it is a one-on-one use, the pump head should not be a problem. If multiple water-cooled chillers are connected in parallel to form a system for multiple cooling applications, the resistance of the piping system needs to be taken into consideration, and the pump with a large head need to be calculated.

 

6, control and regulation requirements: generally refers to pressure control and temperature control and regulation;

 

7, chiller various self-protection function requirements:
