Product Description

The ‘Swarg Systems & Instruments’ heat pump is a compact, self contained unit. It uses R-12 refrigerant and a hermetically sealed compressor. (Refrigerant R-134A can also be supplied, instead of R-12) Both the condenser and evaporator are continuous water circulated. Flow of water in condenser and evaporator and of liquid refrigerant are measured by rotameters. Energy input to compressor is also measured and balance of heat added during the cycle and heat removed by the condenser can be checked. Also actual, theoretical and Carnot COPs of system can be determined and principle of energy conservation by heat pump can also be studied. Heat transfer coefficients on coils of condenser and evaporator can also be studied.

SPECIFICATIONS

2) Condenser & Evaporator – Continuous flow water circulated coils with insulation outside.
3) Thermostatic expansion valves of suitable capacity.
4) Rotameter for liquid refrigerant flow measurement.
5) Rotameters for water flow measurements – 2 nos.
6) Energy meter for compressor input measurement.
7) Thermometers for measurements of temperature at various points in the cycle – 4 nos.
8) Pressure gauges for condensing & evaporating pressure (i.e. high & low pressure)
9) Ammeter for compressor current
10) Controls and safety

  • Pressostat (i.e. High/low pressure cutout)
  • Overload protector for compressor.
  • Filter cum drier for refrigerant.
  • Fan for compressor cooling.

A technical manual will be supplied with the unit.
Also, the unit is provided with an attractive & rust proof powder coating.
