  As we know that the simplest way to build heating system for hot water for dormitory is adopting boiler with coal burning ,which will cause CO2 increase for the earth. Here is the good example how to design the heating system with energy saving heat pumps to protect the environment. The project is the central air conditioning project and hot water project of a pharmaceutical factory dormitory building, canteen. The dormitory building has a total air conditioning area of 5700 square meters, 200 people and the canteen area of 1044 square meters. In the original design institute scheme, 14 air source heat pump units are used in the dormitory building, 4  air source heat pump units  are used in the canteen, and the machine rooms are located on the roof of each building. Our company has optimized the system design: (1) The dormitory building and canteen are combined into one system (2) The system adopts air source multi-functional unit.

  The exhaust temperature of the compressor is the temperature of the exhaust gas after the compressor does work (compresses the gaseous refrigerant). It is usually fixed within a range. By observing the temperature change, the working condition of the compressor can be predicted and the occurrence of safety-threatening events can be prevented. . The exhaust temperature is an important parameter in the operation of the refrigeration compressor of the industrial chiller, and it must be strictly controlled. If the exhaust temperature is too high, it will cause the special refrigeration compressor of the   industrial chiller   to overheat, especially for the piston of the piston chiller. Refrigeration compressors have a serious impact, and the main hazards are shown in the following aspects. 1. Excessive exhaust temperature of the compressor will directly reduce the gas transmission coefficient, increase the shaft power, and reduce the viscosity of the lubricating oil, which will cause ab

  There are many parts of the   screw chiller , among which there are several major components, namely the compressor, condenser, evaporator and microcomputer control system of the screw chiller. The operation panel and computer control system of the screw chiller are very important. Therefore, the four parts of compressor, condenser, evaporator and microcomputer control system are the core parts of screw chiller. Let us discuss these four components in detail. 1. Compressor As the name suggests, the screw chiller uses a semi-hermetic screw compressor as the compressor of the chiller. There are several major brands of screw compressors we use, such as Hanbell compressors from Taiwan, Bitzer compressors from Germany, or Fusheng compressors from Taiwan. These compressors have reliable quality, low failure rate and high energy efficiency ratio. In contrast to screw chillers, there are scroll chillers and piston chillers. The main brands are Copeland, Danfoss, Bitzer, etc. We won't tal

  The   industrial chiller   is a refrigeration equipment that can provide industrial cooling water. Industrial chiller is used in a wide range of industries, such as: electroplating, plastics, electronics, food, card making, chemical industry, machining, laser and other industries. There are two cooling methods for the chiller, one is direct contact between water and the material to be cooled, and the other is indirect contact. In the industrial production process, in order to cool the production medium, in order to ensure that the production equipment works at a normal temperature, to absorb or transfer the excess heat of the production medium or production equipment, cooling water is used. The cooling water and the cooled medium are separated by the heat exchanger wall or equipment, which is called indirect cooling water. Direct cooling water refers to the cooling water that is in direct contact with the product or semi-finished product for cooling in order to meet the needs of the

  What is the   explosion -proof evaporative chiller ? And how to produce a best qualtity of explosion proof Water Cooled Chiller Low Temperature Chiller? H.Stars Group shall inform you all the details as below. In industries that need chillers to operate in dangerous conditions, explosion-proof chillers are the solution,because explosion-proof chillers have a reinforced design to protect the chiller’s components from ambient flammable materials that could cause an explosion. Explosion Proof Safety Chiller provides process or space cooling in harsh or explosive industrial applications. Chillers utilized within hazardous environments must have adequate physical protection and special safety features built-in to prevent damage to sensitive components. H.Stars explosion- proof equipment and its components are manufactured in strict accordance with relevant requirements of GB3836,a national explosion-proof standard, and explosion-proof certificate shall be obtained for it. It can be used i

  Generally speaking, everyone will have doubts when purchasing a   chiller . I don't know how to judge the chilled water flow of the chiller? From what aspects should the water flow of the chiller be considered? Today I would like to share with you four suggestions: 1. Detection of return water temperature and outlet water temperature of the chiller (the unit needs to be in normal state): 30 minutes after starting up the unit, you can read the temperature of the inlet and outlet water when the unit is running through the parameters of the unit's control system or the inlet and outlet water thermometers of the unit's chilled water system. The difference should be ensured to be about 4-6 degrees. If the water temperature difference is too large, it means that the water flow of the water system through the plate type device is too small, which may cause the unit to fail to operate normally or be damaged. 2. Water pressure detection of the inlet and outlet pipes of the  chille

  Industrial Chillers   are widely used, providing cooling water systems for industrial production and helping companies improve product output and quality. Therefore, we need to understand how to use chillers simply and correctly to avoid problems during use and delay production. Let us briefly understand the use of chillers from the following aspects. One: the protection of the chiller: 1. Check whether the voltage is normal, lack of phase, 2. Check and record the running current. 3. Measure and record whether the high and low pressure and temperature control temperature are normal. 4. Under normal conditions, the high pressure is 1.5MPa / the low pressure is 0.45MPa4 Check whether the interlocking control circuit device is loose and aging. 5. Check whether the oil level and oil temperature are normal. 6. Check the compressor for abnormal sound and abnormal vibration. 7. Refrigerant system test. 8. Overall commissioning and testing. 9. Regularly check whether the quality of the chill
