Refrigeration Principle Of Low Temperature Chiller

The refrigeration principle of the so-called low temperature chiller is to use the artificial method, compressor refrigeration, through energy consumption, in a cycle process, in the process that cooling materials take away the heat. Generally speaking, the compressor is use to refrigerate. With the refrigerant, the low boiling point material is used as the medium. The refrigerant is compressed in the compressor, the saturation temperature is higher than the ambient temperature, then it passed through the condenser and is condensed into liquid, liquefied through the throttle valve, and then the heat is absorbed by the cold medium to become the low pressure steam, finally it returns to the compressor cycle.

In addition to compressor refrigeration, there is ammonia refrigeration. However, the overall cost of compressor refrigeration is lower than that of ammonia refrigeration. So now, we tend to choose compressor refrigeration.

After understanding the principle of refrigeration, the selection of a series of equipment parameters such as water flow, outlet temperature and cooling capacity of low temperature chiller should be fully understood in order to make a better selection.

Of course, the refrigerants of low temperature chillers can be environmental refrigerants as far as possible, for the sake of more energy saving and environmental protection and in line with the demand of the public.

What Decides the Price of the Heating Cooing Circulator?

The price of heating cooling circulator is determined by raw materials, manufacturing overhead, technical cost, impacting on the final quotation.

The heating cooling circulator is made of shell and internal parts. The shell is applied standard SUS 304, which can be also customized with plastics (standard color 7035). Influenced by national industrial policy recently, the price of stainless raw materials has been on the rise, especially the environmental factors limit the production, causing many plants to stop manufacturing or limitation. It is predicted that the price will raise continuously. To adhere to the principle of no shobby work, the production cost increases but the sale prices repeat so that the profits shrink.

It provides the customers with proposal and technology of controlling the cold and heat, temperature control system with stable property, extending the service life of heating cooling circulator at the most extent. In daily life, we should know about the maintenance method.
The manufacturers suggest that to check the fastening bolt of power wiring if it is loose, the normal status of high or low pressure value, and the running current or insulation resistant regularly.

It is important that if the device for drying and filtering of heating cooling circulator and sight glass are running normally. If the exit frosts, it indicates the filter is blocked which needs clean filter; if the sight glass demonstrates the wetness ( it turns red), the core of device for drying and filtering wants to be changed.

It is vital that lubricating lube of heating cooling circulator compressor works. When operating, the fuel level is lower than two of thirds of oil sight glass, lubricant should be added; if there is foul or deterioration, lube should be replaced, and filter ought to be cleaned or changed; at the same time, filter core should be changed.

It is suggested that when heating cooling circulator has been used for a long time, conduction oil should be checked every three or six months, and the replacement is determined according to the practical situation. The heating cooling circulator of Guanya in Wuxi applies totally-enclosed circulation line where heat transfer oil will not be leaked or polluted. Pay attention to the replacement when foreign matter or water go into the oil box.

Please be informed by manufacturers that if the heating cooling circulator is not used for the time being, to clean the conduction oil left in the pipe, and to maintain and keep dry.
