A, basically see the refrigerating capacity of the medical device manufacturers need to how much? If the capacity is less than 30 pieces can choose vortex chiller, more than 30 pieces of advice with screw water chillers or centrifugal chiller.

Second, the environment is the wind cold water machine or water cooled chillers,

The wind cold water machine installed in outdoor, units, air-cooled condenser, air blower is directly with wind cooling.

Water, cold water machine installed in indoor, the unit of condenser cooling water, cooling water to the cooling tower cooling. The wind cold water machine features easy installation, air cooling is all-in-one, convenient than water points, generally do more air-cooled small machine

凌堃 medical refrigeration equipment characteristics: such as magnetic resonance equipment, must continuously provide reliable cold source, east star develop the dual system of industrial water chillers, failure occurs when a refrigeration system unit, another automatically put into operation in the refrigeration system, and increase system reliability follows.

The most powerful ventilation pipe quality protective measures

The most powerful ventilation pipe quality protective measures, ventilation pipe quality of protective measures, have the following content.

1, the quality problem of the produce, hanger not brush oil and derrick is too long; Protective measures: to increase the sense of responsibility system should be in a timely manner after the oil derrick interception should carefully check the elevation.

2, the quality problem of the produce, hanger spacing is too long; Protective measures: to carry out standard installation after serious review for the spacing is too large.

3, ventilation pipe equipment welding flange, waist band. Protective measures: carefully check before installation, found that the problem should be timely adjustment.

4, duct production line of screw leakage wear loose or tight; Protective measures: to increase the sense of responsibility of the flange hole spacing should timely adjust the distance.

5, ventilation pipe equipment duck mouth long twisted; Protective measures: riveting canvas should be straight, for strap to compress canvas don't leak.

6, ventilation pipe equipment modification rivet hole not blocked; Protective measures: the modified application of sealant plugging.

7, ventilation pipe equipment gasket fall off; Protective measures: process, in strict accordance with the flange surface should be clean.

The sealing glue, ventilation pipe equipment is not; Protective measures: the strict discipline standard of tuyere installation requirements

How to solve the problem of closed cooling tower of frost?

Closed cooling tower of the working fluid (water, oil or other liquid) flow in the coil, the walls of the coil is spraying water, fluid through the pipe, heat stroke saturated with water and air of damp and hot steam, heat is discharged into the atmosphere by fan, spray water is in the process of circulation through PVC heat sink lower temperature, and fresh form shui cocurrent flow into the wind, coil is mainly rely on the hot and humid heat conduction mode, this operation principle of the important characteristics is the biggest may inhibit scale generated outside of the coil.

A, add antifreeze: local minimum environmental dry bulb temperature (temperature) for - 10 ℃, 10 ℃ or below - will add 20-30% high levels of antifreeze, actually don't ice freezing as criterion, the user can be flexible according to actual condition.

Don't two, stop (long-term) before use compressed air to blow dry the water in the cooler, closed cooling tower water discharge clean first, then the compressed air in filling the vent place, residual water from the drain will rule out again.

Three, use electric heating processing: when the environment temperature is only 0 ℃ or so, can consider on the piping or the circulation water tank, electric heater, or other heat source, to improve the surface temperature of the closed type cooling tower, so as to achieve the purpose of antifreeze.
