Chiller is a kind of water cooling equipment, chiller is a kind of cooling water equipment that can provide constant temperature, constant flow and constant pressure.
Chiller, in the industry is divided into air-cooled chiller and water-cooled chiller two kinds of chiller in the temperature control is divided into low-temperature chiller and room temperature chiller, room temperature temperature is generally controlled in the range of 0 degrees -35 degrees. Low-temperature machine temperature control is generally in the range of 0 degrees - minus 100 degrees or so.
Principle of operation
Refrigeration medium (i.e., refrigerant) in the evaporator to absorb the heat of the cooled material and vaporize into steam, the compressor continuously will produce steam from the evaporator, and compression, compressed high-temperature, high-pressure steam is sent to the condenser to the cooling medium (e.g., water, air, etc.) exothermic condensation of high-pressure liquid, the throttling mechanism to reduce the pressure into the Evaporator, vaporize again, absorb the heat of the cooled object, and so the cycle begins again and again. When heating, the refrigerant through the four-way valve to change the direction of refrigerant flow, refrigerant flow direction and refrigeration is just the opposite, the refrigerant first through the evaporator, and then back to the condenser, and finally back to the compressor.
Use
The chiller may be used in many areas, the main areas of application are:
⒈ chiller can be used in supporting vacuum equipment. Such chillers also meet the needs of high-quality vacuum equipment, such as molecular pumps, small vacuum coating machine.
Peak chiller used in supporting medical laser equipment. This type of chiller unique water quality treatment characteristics, making it an ideal choice for medical laser equipment supporting supporting laboratory equipment. This series of chiller is also widely used in atomic absorption spectrometry analyzer, fermentation device, reaction kettle, electrophoresis, etc.
Chiller in the use of the process must pay attention to: first of all, before the use of the tank should be added to the liquid medium, followed by the use of the working power supply should be based on the model to determine the power supply power supply power supply power should be greater than or equal to the total power of the instrument, the power supply must be a good grounding, and once again the chiller should be placed in a Dry and ventilated place, after being and come to that side away from obstacles 400mm distance, and finally after the use of the chiller, all the switches are set to shutdown state, connect the power plug, with a suction ball, skin tube to the liquid in the tank sucked dry.
3 chiller can be used to supporting experimental condensing equipment. Such as rotary evaporator, distiller, condenser tube, with high and low temperature control, temperature stability, condensation efficiency, can effectively improve the recovery rate. At the same time its fluid purification function, can avoid circulation pipeline clogging, growth of microorganisms.
The sung chiller is used in conjunction with semiconductor laser equipment. Semiconductor laser equipment has high water quality requirements due to its special structure.
