Professional cold room installation services in Kenya. Reliable commercial refrigeration featuring advanced compressor technology.
Find the best installation location
Firstly you should consider the best location for air circulation to install the Unit Cooler (also called evaporator unit), secondly consider the direction of the cold room structure.
The gap between unit cooler and cold room inside wall should be larger than the thickness of the evaporator.
Tighten all slings
Should tighten all the evaporator slings when installation, meanwhile perforate and seal the bolts & slings with sealant to prevent air leakage.
When the evaporator is too heavy, you should use the No. 4 or 5 angle iron as the beam, and remember spanning the lintel to another top plate and wall plate in-order-to reduce the load-bearing.
Cold Room Condensing Unit Installation
Equip with oil separator
Both semi-hermetic and enclosed compressors should equip with an oil separator, and fill an appropriate amount of oil.
When the evaporation temperature is lower than -15°C, you should install a gas-liquid separator with appropriate amount of refrigeration oil.
Install rubber seat onto compressor base
Should install a shock-absorbing rubber seat onto the compressor base, remember to reserve the maintenance space when installing the Condensing Unit, which is convenient to observe instruments and adjust valves.
Select right copper pipe diameter
Depending on the size of the suction and discharge valve interfaces of the compressor to select the copper pipe diameter. You should increase the pipe diameter when the separation between the condenser and the compressor exceeds 3 meters
Follow the nameplate
The pipe diameter of the liquid storage tank is based on the exhaust and liquid outlet pipe diameters which are indicated on the nameplate.
The suction pipeline of the compressor and the return pipeline of the evaporator shouldn’t be smaller than the size indicated on the nameplate, in order to reduce the internal resistance of the evaporation pipeline.
Pipes need inclination
The exhaust pipe and return pipe should have a certain inclination. When the condenser position is higher than the compressor, the exhaust pipe must lean towards the condenser and install a liquid ring at the exhaust vent of the compressor, which can prevent the gas (from cooling and liquefying after shutdown) backflow to the high-pressure exhaust vent, and causing liquid compression when the machine restarted.
Install a U-shaped bend
You should install a U-shaped bend at the evaporator outlet of the air return pipe, and the air return line should incline toward the compressor to ensure smooth oil return.
Should install the expansion valve as close as possible to the evaporator!
