MECHANICAL HEAT PUMP TRAINER : PSAW-209RA
Heat Pump is a
device to pump heat from one source to another. The heat obtained by heat pump
is more than that could be obtained by direct electrical heating. The apparatus
consists of refrigeration system with water cooled shell and coil type
evaporator and condenser.
SPECIFICATIONS:
1.
Compressor
– Hermetically sealed compressor using R-12 refrigerant, having capacity 0.3
tons of refrigeration. Condensing pressure – max. 15 Kg/cm2 (Actual pressures
will depend upon working conditions).
2.
Condenser
– Shell and coil type with continuous water flow arrangement.
3.
Evaporator
– Shell and coil type with continuous water flow arrangement.
4.
Expansion
Valve – Internally equalized thermostatic expansion valve.
5.

–
a)
Rotameter
for condenser & evaporator water flow rate measurement.
b)
Rotameter
for liquid refrigerant flow measurement.
c)
Pressure
gauges for condensing and evaporating pressure – 2 Nos.
d)
Thermometer
for refrigeration cycle & water temp, measurement – 7
e)
Wattmeter
for compressor input measurement.
f)
