Our mainly clients:

1. Cold storage (such as 1500 cubic need -18 degrees), to calculate what his compressor P base number?

A cubic cooling capacity by 80-180W to count (to put in the product temperature below 10 by 80-120W, more than 20 with 120-180W) evaporating temperature and cooling temperature difference of 7 degrees with a cooling capacity multiplied by the number of cubic meters in find the corresponding evaporation under refrigeration temperature, the compressor will be able to draw the P number.

2.At present, I can do a minimum number of degrees cold? 
-80 To +20 can be done, the temperature reaches -30, -40 required two-stage compressor, -60 degrees required cascade unit.

3. A unit with a much needed refrigerant? 
Cooler 1P equipped 1KG by Freon 
Calandria by 1:1.5 times with 
This is a relative value, the specific length and size of brass, copper and calandria tube size, length related.

4.Cooler brass wall thickness? 
European type used 9.52,0.2 D-type 16mm, 0.35 
Pipeline connecting pipe will be slightly thicker because of the way against the run will encounter in the fin zero chance encounter. 
10 years ago there 0.5,0.8 chillers, heavy brass with updated technology growing in thin, the thinner the better efficiency of the sensor, the higher the efficiency, does not affect the product performance and life, because he the TP2 material, good toughness.

5.Refrigeration units used car? 
As long as refrigerated trucks to meet the requirements of 220V or 380V power supply, can be equipped according to the standard recommended by semi-hermetic compressors, refrigerated trucks, but due to the activities in the process may be bumpy, so the higher requirements of the refrigeration unit. 
Standard size: 20 cubic feet container 30, 40 and 60 cubic foot cabinet 
Screw machine does not feature in the refrigerated vehicle.

6.What materials need to do a cold? 
Need to do a cold: cold library board (with insulation), cold storage doors, refrigeration units (air-cooled or water-cooled), cooling fan or exhaust tube evaporator, control box, expansion valves, refrigerant, copper wires and connections as well as supporting the takeover and so on. 

7. What accessories within KUB refrigeration unit? 
Compressors, condensers, motors, reservoir, filter drier, oil separator (optional), gas-liquid separator (optional), solenoid valves, pressure controllers, the sight glass (optional), pressure gauge , valves, junction boxes, brass floor joints. Where optional, do not require a surcharge on the standard unit.
