RANGE OF EXPERIMENTS TO BE CARRIED OUT:
1. To observe the working principal of heat pump cycle.
2. To determine Actual cooling C.O.P, Carnot C.O.P., Theoretical C.O.P.,Actual heating C.O.P., Relative C.O.P., Ton of Refrigeration Etc.
3. To determine the efficiency of the heat pump system.
4. Observe the working of refrigeration cycle also.
TECHNICAL DESCRIPTION :
Heat pumps are refrigeration systems in which the rejected heat is at least as important as the refrigeration effect. Heat pumps have been referred to as reverse-cycle refrigeration systems.
A heat pump, in the common thermodynamic sense, is a system in which refrigeration components ( compressors, condensers, evaporators, and expansion devices ) are used in such a manner as to take heat from a source ( air, water ground, etc. ) and give it up to a heat sink ( air, water, ground, etc.) that is at a higher temperature than the source. For many applications, the heat pump is designed in such a manner as to reverse the cooling and heating functions. This allows the use of the same equipment for both heating and cooling and individual structure. Other applications are designed to simultaneously utilize both the heating and cooling effects obtained from the cycle in the same structure.

RANGE OF EXPERIMENTS TO BE CARRIED OUT:
1. To study all components used in Automobile Air Conditioning system.
2. To study the Vapor compression Refrigeration cycle.
3. To study the cooling, humidification,& dehumidification process.
4. To determine the Refrigeration Effect, Work Input, Actual C.O.P.,Carnot C.O.P., Theoretical C.O.P., Relative C.O.P., Ton ofRefrigeration, and Plant Efficiency.
TECHNICAL DESCRIPTION :
The equipment consists of a hermetically sealed compressor, air cooled condenser, blower unit to force air through a duct mounted on frame, an evaporator adopted in the duct, heaters of suitable capacity are clamped in the duct.
The power to the heater can be controlled & the air is warmed while it passes over the heater. Rotameter is used in the regeneration circuit which measures the flow of refrigerant (R-134a). The mass flow rate in the duct can be varied by arrangement provided on the blower unit.

There is arrangement provided on the blower unit. There is an arrangement for
humidification achieved by introducing steam in the duct. The relative humidity of
air at inlet & outlet can be measured by a dry/wet bulb thermometer. An
expansion valve is provided in the circuit for throttling the gas from HP to LP.
There are two gauges for measurement of high & low pressure. Four
thermocouples are placed to measure the temperature of gas at the evaporator &
condenser, with help of digital temperature indicator. HP/LP cut out is provided
for the safety of compressor. The duct is insulated from out side to avoid the
heat loss.
The control panel consists of switches starter, voltmeter ammeter etc. The
measurement of power consumption of compressor by using energymeter.
The refrigeration circuit & duct are mounted on a fabricated frame. The blower
driven by motor is mounted on separate frame.
