The normal detection method of the integrated machine of the high and low temperature circulation device of medicine

During the use of the integrated medical high and low temperature circulation device, if the heat transfer medium is deteriorated or contaminated by other substances, the use effect of the equipment will decline and age
.

1.
Refrigeration system: Check whether the pipes in the refrigeration system are cracked, damaged, frosted and dew condensation, etc.
; whether there is friction between the refrigeration pipes, pipes and shells, especially the refrigerant pipes Whether there is leakage at the welding point and the joint of the equipment joint, but there will be oil pollution at the leakage point.
You can also use a clean soft cloth or soft paper to scrub the joint between the welding section of the pipeline and the joint, and check whether there is oil pollution to determine whether there is leakage
.

2.
Electrical system: Check whether the fuse of the electrical system is blown, whether the insulation of the electrical wire is intact, whether the circuit board is cracked, whether the connection is loose,
etc.

3.
Ventilation system: Check whether the air filter, heat exchanger coil and fins are too dusty; whether the air inlet and outlet are dredged; whether the fan and fan blades work normally; whether the wind force is normal,
etc.

4.
Water system: check whether there is water leakage; whether the water inlet and outlet are dredged; whether the pump works normally
.

Whether the working sound of the compressor is normal, whether there is any abnormal sound, whether there is any noise in the operation of the fan and the water pump, whether the noise is too loud,
etc.

　　5.
Under normal conditions, the temperature of the condenser gradually decreases from top to bottom, and the temperature at the lower part is slightly higher than the ambient temperature
.

If all the condensers are not hot or the upper part is slightly warm, or although it is hot but the temperature of the upper and lower adjacent pipes is significantly different, it is abnormal
.

　　6.
Under normal conditions, the evaporator will feel cold and sticky if you put your finger dipped in water on the surface of the evaporator
.

The dryer and the capillary tube at the outlet should have a warm feeling under normal conditions.
If it feels lower than the ambient temperature or there is dew condensation on the surface, and there is a temperature difference in each section of the capillary, it is abnormal.

.

When the drop exceeds a certain limit, its thermal conductivity will be greatly reduced, and serious carbon formation will occur, causing damage to the heating tube and even failures such as pipeline blockage
.

Therefore, it is necessary to regularly replace the heat transfer oil and check the equipment system, so as to ensure the heat transfer effect and normal operation
