H.Stars (Guangzhou) Refrigerating Equipment Group Ltd.

  Project Overview This project is for one of the new factory buildings for one of the 500 fortune company of  Dairy industry . The factory new workshop building area is about 17,000 square meters, with a total of 2 floors. H.Stars Group has helped this company to design the energy saving cooling system by adopting  low-temperature chiller  and low-ambient temperature air source heat pump unit Project Requirement Project design This project has air conditioning system, ice water system and hot water system, which has both cooling demand and heating load. The design of a system for the project can meet all the above requirements. Under the premise of ensuring safe and reliable operation, this scheme should balance the cold and heat as much as possible to make the system efficient and energy-saving. See the system flow chart for details. The whole project designs a refrigeration station, equipped with a flooded type  water-cooled low-temperature chiller  (wit...

  The application of chillers is very wide, including plastic industry, chemical industry, packaging industry, printing industry, food industry, etc. Today we will talk about how to choose chillers in the food industry. The   water chiller   used in the food industry needs to be used for rapid cooling of all kinds of food after heating, so that it can be suitable for canning and bottling requirements. In addition, various fermented foods require different cooling temperatures to stabilize fermentation needs and improve fermented products. To ensure the quality of fermentation, it is also used in the pharmaceutical, chemical industry, and refrigeration equipment. When choosing a chiller in the food industry, first consider the temperature of the chilled water required in the process, whether to use a medium-temperature chiller or a low-temperature chiller, and secondly, consider whether the cooling water needs to be in direct contact with the food? If it is to directly coo...

  The normal and safe operation of the chiller is inseparable from the refrigerant. It is the working medium that circulates in the chiller refrigeration system to achieve refrigeration. The commonly used refrigerant types for chillers are: R22, R407C, R404A, R410A, R134A, R507... Because R22 refrigerant is not environmentally friendly, most countries have now banned the use of R22. Therefore, for Omar chillers, high temperature The chiller uses R407C refrigerant, and the   low-temperature chiller   uses R404A. Of course, R134a, R410A, etc. can also be used according to user requirements. So, how to choose the appropriate refrigerant type for the chiller? R22: Because R22 destroys the ozone layer, many countries have now banned the use of R22. Therefore, the chillers we export are generally R407C systems, unless customers require special requirements. R407C: R407C is a mixture of R32 refrigerant and R125/refrigerant plus R134a refrigerant in a certain proportion. It is an...
