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.

  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.  Measurements -

    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)   Ammeter for compressor current measurement.

  6.  Controls -

    a) HP/LP cutout for compressor.  b) Overload protector for compressor.

    c) Gate valve to control water flow rates.
