High efficient evaporative cooling technology for refrigeration industry

图片
After years of practical exploration in the refrigeration industry, the increasing maturity of evaporative cooling technology has provided new ideas for improving the energy efficiency of chillers. Evaporative condensation technology is efficient, energy-saving and green. By reducing the condensation temperature, the energy efficiency of H.Stars chillers is increased by about 20% More and more users prefer evaporative chillers Principle of  evaporative condenser The evaporative condenser combines the condensation process of the water-cooled condenser and the cooling tower with the water cooling process. It uses cooling water to form a thin film on the surface of the heat exchanger, and the water film directly contacts the forced air. The material to be cooled transfers heat to the water film. The water film undergoes unsaturated evaporation and exchanges and transfers heat and mass with the air. Finally, the air takes away the heat. It improves the traditional cooling method in

How to produce a coil heat exchanger

图片
As we all know,  coil heat exchangers  are very important part of a air cooled chiller and air source heat pumps. How does a factory produce coil heat exchangers ? Below are total 9 different procedures to maintain superior quality products. ​ 1. Material preparation (copper tube, end plate, side plate, middle support plate, short U-head, gas / liquid tube, liquid distribution tube) 2. Fin stamping (punching machine, fin die) mainly produces corrugated fins or louver fins according to requirements, including multiple rows and multiple sections of fins. 3. Copper tube cutting (bending machine, cutting machine) according to the need to discharge long U-tube, straight tube. 4. String tube, pre-assemble the fin, copper tube and end plate together manually 5. Tube expansion (horizontal tube expander, portable tube expander) is mainly to expand the pre-assembled copper tube and finned copper tube into a coil with high heat exchange effect, and complete the

Singapore Plastic Wrap Factory Project

图片
Provide automatic temperature regulating chilled water system for  plastic wrap production line Anti-corrosion industrial chillers Project  Chiller  Specification : 3 sets of 300kW Anti-Corrosion Type Air-cooled Chiller with water pump and tank designed as all in one unit to save labor cost at site. (2) Chiller adopts 304 stainless steel frame design. In humid and rainy environment, the operating life of the unit can reach more than 15 years; (3) Chiller adopts flooded type evaporator, the heat transfer effect is 30% higher  than the ordinary evaporator; (4) The heat exchange tube of the chiller is made of 316 stainless steel, which can  effectively anti corrosion from sea water ,to ensure  the chilled water in contact  with the plastic wrap with food-grade. It also can reduce the subsequent  maintenance cost. (5) The chiller compressor and condensing fans are variable-frequency control,  which can freely match the variation of refrigerating capacity demand on the  production l

H.Stars High Efficiency Water Source Heat Pump for Greenhouse Project

图片
Project Reference ​ Flower greenhouse plantation in Hubei. The total area of the greenhouse is 175000㎡. According to different temperature and humidity requirements of different flowers, the  heat pump unit  is needed. Requirements 1. 1 the indoor temperature of the greenhouse is 30℃±2℃ in summer and 20℃±2℃ in winter. 2. The relative humidity in summer and winter greenhouses is 70%~75 Solution According to the customer's needs for greenhouses and equipment use safety, energy saving and environmental protection investment cost operation cost requirements. Equipment selection has fully considered the environmental climate around the project, through the analysis of outdoor air parameters. It is known that the local groundwater resources are relatively rich, suitable for the use of water source heat pump units we provided 12 H.Stars flooded type water source heat pump units, the internal vertical jet AHU. Advantage 1.  Water source heat pump unit
