TD 05 MECHANICAL HEAT PUMP TEST RIG (WATER TO WATER)

DESCRIPTION

 

The heat pump comprises of a compressor, a condenser with fan, an expansion valve and an evaporator. These components are connected to each other via a refrigeration circuit. The refrigerant circulates in the refrigeration circuit powered by the compressor. Condenser and evaporator are provided with water cooling facility. In condenser, heat is taken away by the water in order to reduce the temperature of the gas in pipeline and hence the temperature of the water gets increased. In evaporator heat of water is absorbed by the refrigerant gas results in reducing the temperature of the water in the evaporator chamber. In this way the water in the evaporator chamber gets cooled and the water that is available in the condenser chamber gets heated-up by this same refrigeration cycle. In this way by using the same refrigeration cycle temperature of water in one chamber gets increased while in another gets decreased.

 

EXPERIMENTS

 

  • Design and operation of an water-to-water heat pump
  • Representation of the thermodynamic cycle in the log p-h diagram
  • Energy balances
  • Dependence of the real coefficient of performance on the temperature difference (water-to-water)

 

FEATURES

 

  • Clear and self descriptive set-up
  • Color coding of copper pipes for quick and easy understanding of refrigeration cycle
  • Open circuit of cycle for convenient understanding of various components.
