Mechanical Heat Pump Test Rig Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-9359
Jlab Export is a leading Mechanical Heat Pump Test Rig Manufacturer,and suppliers in India
A heat pump uses the vapour compression cycle to move heat from a cooler source to a warmer one. On this test rig both the condenser and the evaporator are water cooled. The heat taken from one water stream and given to the other can then be measured. It stands on a mild steel square tube frame with cast iron wheels and an instrumentation panel.

Heat Pump Experiments for Students
With water flowing through both heat exchangers, students record the flow rate and the inlet and outlet water temperatures on each side. The heat delivered at the condenser is the mass flow times the specific heat of water times the temperature rise. The heat taken in at the evaporator is found the same way from the temperature fall. Dividing each figure by the compressor power gives the heating COP and the cooling COP.
A second run changes the condenser water flow or its inlet temperature, and students see how a higher delivery temperature lowers the heating COP. Teachers can compare the results with the shell and coil Mechanical Heat Pump Trainer. The air-source Heat Pump makes a third comparison, since it takes heat from air in a finned tube evaporator.
Frequently Asked Questions
How is the heating COP of a heat pump defined?
It is the heat delivered at the condenser divided by the work put into the compressor. On this rig the heat delivered comes from the condenser water flow and its temperature rise.
Why is the heating COP higher than the cooling COP?
The condenser rejects the heat taken in at the evaporator plus the compressor work. For the same cycle the heating COP is therefore close to the cooling COP plus one, less the heat lost from the rig to the room.
Why are both heat exchangers water cooled?
Water flow and temperature are easy to measure, so students can work out the heat on both sides and close an energy balance against the compressor input. With air on one side, the heat flow is much harder to measure in a college lab.
Why should the rig run on a steady supply voltage?
The compressor draws more or less power as the mains voltage swings, and a low voltage can make it stall at start or overheat. The COP divides heat by the power input, so a wandering supply spoils the result. Readings taken minutes apart then cannot be compared.
Is the rig a refrigerator or a heater?
It is both, in one cycle. The evaporator cools its water stream while the condenser heats the other. Whether it counts as a heat pump or a refrigerator depends on which effect is wanted, and the COP is defined to match.
