Wind chilled water machine _ Snow Dragon plating chilled water cooling machine (certified) _ Changan chilled water machine provided by the Dongguan City-long Refrigeration Electrical and Mechanical Equipment Engineering Co., Ltd .. Dongguan City-long Refrigeration Electrical Equipment Engineering Co., Ltd. (www.dgxuelong.com) is a professional engaged in "sales, installation, maintenance, electrical and mechanical equipment (excluding Holds for repair of electrical equipment), refrigeration equipment," the business, the company adhering to the "integrity management, service intentions, "the idea, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Fu. Hermetic compressor as a whole, together with the motor of a compressor device in a sealed steel formation. From the appearance of the suction and discharge fittings and electrical wires only compressor; compressor housing is divided into two parts chilled water machines, compressors and motors mounted air-cooled chiller rear, top and bottom with a welded steel welded into one. Usually can not be removed, so use reliable machine. In closed refrigeration compressor, another piston-type compressors and scroll compressors. Hermetic scroll compressor refrigeration Its structure consists of the following components: a rotary inlet and outlet valves; gauge ports; built-in overload protection; elastic base; crankcase heater; built-in oil pump. The biggest advantage scroll refrigeration compressor are: a simple structure: only two compressor body parts (dynamic disk, fixed disk) can be replaced by a piston compressor 15 parts; 2 High: suction gas processing and conversion gases are separated, to reduce heat transfer between the suction and treatment Carrier chiller, can improve the efficiency of the compressor. Scroll compression process and the transformation process is very quiet. Chiller Chiller is a vapor compression or absorption refrigeration cycle to achieve the effect of the machine through. Chiller in the industry is divided into air-cooled chiller, and two kinds of water-cooled chiller, chillers on the temperature control is divided into low temperature chillers and chiller room temperature, room temperature control in the range of 0 degrees -35 degrees. Cryogenic temperature control is generally at 0 degrees - about 120 degrees below zero range. Generally manufacturers will produce water-cooled and air-cooled two air-cooled industrial chiller, contains within its body and pump water tank insulation, plus cooling towers no longer to heat. Very easy to install and move. Cooled industrial chiller, can be divided into open, closed (some called a box) and screw. Water-cooled industrial chillers, cooling towers and have another installation of water pumps to extract the water cooling. in order to achieve better efficiency cooling effect.
