H.Stars (Guangzhou) Refrigerating Equipment Group Ltd.

  H.Stars Group   has recently signed a contract with 90℃ dual source heat pump unit project for one of the famous automobile factory to replace the traditional boiler. Below are the features of high-efficiency 90-degree dual source heat pump: 1. Special design and customized size for easy installation. 2. Adopt the special compressor of Hanbell high temperature heat pump, with high compression ratio, high energy efficiency, stable performance, multi-level energy adjustment, accurately matching the load change of the unit, low noise and low vibration. It has a wide operating range and can adapt to different operating conditions. 3. Environmental protection adopts environmentally friendly refrigerant: R134A. 4. It is matched with the high-efficiency heat exchanger produced by our factory and adopts the latest high-efficiency heat exchange copper tube to optimize the heat transfer efficiency, compact structure, strengthen heat transfer on the water side and the refrigerant side,...

  Nowadays, chemical plants always consider how to reduce the initial investment and operation cost when they need to install a  low-temperature chiller system for the factory. Because low temperature refrigeration unit is a very important equipment in chemical plant, which plays an important role in safety production. The initial investment of   low-temperature refrigeration unit   is large, and it is also one of the equipment with large energy consumption in chemical plant. How to reduce the investment and operation cost of   Glycol low temperature chiller   and system is very important for enterprises. This is one of H.Stars Group projects for one of the chemical base . The cryogenic unit and chilled water circulation system are designed and implemented .At first, the company's design engineers only chose the Ultra low temperature chiller and system design according to the cooling capacity required by customers. However, with the deepening of the project...

  Recently, when communicating with some customers, we found that we were not very clear about the type selection and system design of low temperature units. However, the   low temperature chiller   is a very important equipment for chemical industry, raw material pharmaceutical factory and other enterprises, and it is also the place with the largest energy consumption for such enterprises. Therefore, how to select the appropriate number of industrial low temperature chiller and design a reasonable frozen water circulation system is particularly important. There is an example on  H.Stars Group  project reference.To us, the key points of  glycol chiller  design ,take the recent project of Anhui Xiangbang Chemical Co., Ltd. as an example, the total cooling capacity demand of the enterprise is 1500kW, and the outlet water temperature is required to be - 15 ℃. According to the experience, the following three points are sorted out for your reference: 1、 Sel...

  The   heat recovery chiller   is a new type of energy recovery chiller. It has one more heat recovery device than conventional chillers，it is an   economical chiller . It can produce hot water for free at the same time when making cold water. The hot water temperature can reach up to 70 degrees. It is very suitable for hotels, guesthouses and pharmaceuticals, electronic constant temperature and humidity workshops and other places that have both cold and heat requirements. Heat recovery chillers types Heat recovery chillers can be divided into two types: partial heat recovery and full heat recovery according to the amount of recovery. Partial heat recovery can recover 30% of the heat energy of the cooling capacity, while full heat recovery can recover the cooling capacity + The equivalent amount of heat energy of the input power. The main features of the heat recovery chillers: The economic benefits of heat recovery chillers are not only energy recovery, but also re...
