H.Stars Group  water cooled chiller unit  always need to adopt cooling tower to supply water to the cooling system . Hence, H.Stars has summarizes the difference between square type cross flow closed circuit cooling tower and traditional open cooling tower. The cooling water of the open cooling tower is directly contact with the air for heat exchange in the packing process, so the purity of the cooling water system cannot be maintained, and the cooling water inevitably absorbs dust and bacteria from the air. However, in the closed cooling tower, the cooling water flows in the coil, and the spray water and air are outside the disc, so the cooling water and the outside air are not in contact, and the purity of the cooling water system can be kept forever. Advantages of square type crossflow closed circuit cooling tower 1. The cooling tower series has the advantages of high efficiency, energy saving, environmental protection, energy saving, stable operation, etc. 2. It can...

Regarding to  water cooled chiller  working system, normally it needs to adopt water cooled chiller, cooling tower, water pump or tank etc.  To familiar with H.Stars Group water cooled chiller system, here we are introducing you the working principle of  square type contra-flow closed circuit cooling towers   first. The working fluid (water, oil or other liquid) flows in the coil clock, the outer wall of the coil is wrapped by the spray water, the heat of the fluid is transmitted through the wall of the tube, and the saturated hot and humid air is formed with the water and the air, and the heat is discharged into the atmosphere by the fan. The parts are blocked and sprayed back to the sink, and the consumption is very small. The spray water reduces the water temperature through the PVC heat-dissipating material during the circulation process, and flows in the same direction as the fresh air. The coil mainly relies on the sensible heat conduction mode...

Heat pump drying technology and traditional drying technology ,which has more advantages? At present, agriculture, food, chemical industry, ceramics, medicine, mineral processing, pulp and paper, wood processing and other industries, all the production process almost all use drying, drying material quality depends on whether a good control of constant temperature. Heat pump drying technology is a mild, close to natural drying method, more suitable for most agricultural products, medicinal materials and other heat-sensitive materials drying. The principle of heat pump dryer is the use of reverse carnot principle of gas compressor pressurized, become (temperature up to 100 ℃), high temperature and high pressure gas entering the indoor side of heat exchanger (condenser), refrigerant condensing liquid heat release of the high-temperature heating drying room air. The materials in the drying room will vaporize and evaporate the moisture in the materials in the form of hot air, and...

Today both Condenser and Cooler are very important heat exchanging components in commmercial or   industrial refrigeration equipments , which are widely applied in many fields. Lots of customers who look for UAR for model selection are curious about the difference between Condenser and Cooler. So let’s make a brief introduction. 1)Phase change doesn’t occur in Cooler while it happens in Condenser. Generally, the difference lies in the spot and tube diameter of inlet and outlet. Connection tube in/outlet diameter varies a lot more than Cooler’s, which can be observed and compare obviously. 2) The second difference between Condenser and Cooler is their configuration of baffle plate. To Condenser its baffle plate construction is usually mounted left and right while Cooler’s are mounted up and down. One reason is their different heat exchange rate. 3) Intercooler has liquid level meter and liquid level control port while Condenser doesn’t have any. For intercooler, its gas inlet and o...
