Typical application of refrigeration heating temperature control system

Dynamic thermostatic control of cold and heat source of high pressure reaction kettle, dynamic thermostatic control of double layer glass reaction kettle, and dynamic thermostatic control of cold and hot source of double-layer reactor.

Microchannel reactor thermostatic control, small temperature control system, steam - feeding system temperature control, material low temperature aging test.
The thermostatic control of the combined chemical cold source heat source, the cooling heating of the semiconductor equipment and the heating temperature of the vacuum chamber are controlled.

Advantages and functions of temperature control system of refrigeration

Temperature range from 120 to 350, performance superior, unique, high - precision, intelligent temperature control.
High cooling power from 0.5 to 1200kW, highest production stability and repeatable results.
Multi-function alarm system and safety function, use plate heat exchanger, tube type heater to increase heating and cooling rate.
7-inch and 10-inch color TFT touch screen graphics display, use magnetic drive pump, no re-seal leakage problem.
Full airtight system, extended thermal conductivity liquid life, very wide temperature range, no need to change liquid media.
Ultra-high temperature cooling technology can be cooled directly from 300 degrees of high temperature.
The principle and the function has many advantages to using staff: because only expansion of cavity in the body heat conduction medium contact with oxygen in the air (and expansion tank temperature at room temperature to 60 degrees), can achieve lower heat conduction medium absorbed by oxidation and the risk of air moisture.
No heat conduction medium evaporates at high temperature, and it can be achieved -80 ~ 190 degrees, -70 ~ 220 degrees, -88 ~ 170 degrees, -55 ~ 250 degrees, -30 ~ 300 degree continuous temperature control without pressurization.


Adopt full closed pipe design, adopt high efficiency plate heat exchanger, reduce the demand of heat conduction liquid, improve the heat utilization rate of the system, reach the rapid lifting temperature.Thermal conductive medium in a closed system, with a container, expand the heat-conducting medium not participate in circulation in the container, whether high or low temperatures, expansion tank temperature to room temperature to 60 degrees, can reduce the heat conduction medium in running the risk of absorb the moisture and volatile.

The outdoor installation of air-cooled chillers makes it easy to be affected by outdoor sunlight, and  the ventilation and the environment and space has a direct impact on the cooling effect of the chiller. Today we are going to talk about the common failure and processing methods:

(1) Frequent start and stop of the compressor: there may be too much or too little refrigerant, resulting in pressure protection switch action which is resulted from too high exhaust pressure or  too low suction pressure, and also poor water system circulation make sevaporator surface frost.

Method: When the refrigerant is too much, the extra can be released at the vent. If there is a shortage, check whether there are leaks of the fluorine and fill the refrigerant.

If the water circulation system is blocked or stored in the air, you should exhaust; if water circulation too small, utilize the open refrigeration water circulation system.

(2) Noisy compressor when running: check whether the expansion valve fails, the temperature package discharges the suction pipe from the compressor, which causes the liquid refrigerant return to the compressor. If it is damaged, it should be repaired, for example, if the compressor is damaged, it should be replaced.

(3) Poor refrigeration capacity: the cause of the poor refrigeration capacity may be the insufficient refrigerantand low evaporation temperature that makes the  por cooling effect of pipeline; poor heat dissipation of the condenser; too large the resistant of the water circulation system,etc..

The refrigerant pipe should be checked for leakage and fill the refrigerant after repairing.You should repair the insulation layer and Clean the condenser to check whether the fan is working properly as well as clean the pipe filter.
