Air Flow and ThermodynamicsAir-To-Water Heat Pump
A table top air conditioning system is used to demonstrate how heat is transferred from air to water.
A water cooled heat exchanger is used as a condenser while the liquid refrigerant is evaporated in an air cooled evaporator. Instruments are provided for measurement of temperatures, pressures, and water flow rate. The system requires outside water supply.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Design and operation of air to water heat pump.
- P-h diagram. . Energy balances.
- Coefficient of performance.
- Overall heat transfer coefficients for evaporator and condenser.
- Effects of loads variation.

Air Flow and ThermodynamicsLaboratory Air Conditioning System
This is an open circuit air conditioning system with transparent window.
The unit consists of a fan, a compressor and condenser, a humidifier, a preheater, a cooling unit, a reheater, and measuring instruments.
Variable speed inlet fan deliver air to the duct. A steam humidifier injects moisture to the duct inlet. The humidified air passes through a preheater, a cooling unit, and a reheater before exit to the atmosphere. Steam generator, compressor and condenser are underneath the duct.
Instruments are provided for measurement of temperatures, pressures, humidity, power, air flow rate, and refrigerant flow rate.
The unit is on a steel frame on wheels.
Instruction manual is also included.

Air Flow and ThermodynamicsRecirculating Air Conditioning Unit (with Climatic Chamber)
This is a recirculating air conditioning unit with transparent windows and a climatic chamber.
Inlet air is cooled and preheated by a heater and latent heat by a humidifier before entering the climatic chamber for demonstration of climate control. The air in the climatic chamber is further heated by a heater and a humidifier before leaving. A fan after the preheater circulates the air. Part of the air leaving the climatic chamber is vented and the remaining is recirculated with make up fresh air entering the inlet duct. The amount of air recirculation is controlled by ventilation flaps. Steam generator, compressor and condenser are underneath the duct.
Measuring instruments are provided for air flow rate, and temperature and humidity at various stages. Additional instruments are provided for measurement of refrigerant flow rate, temperature and pressure as well as power for the compressor and heat sources.
The unit is on steel frame on wheels.
Instruction manual is also included.
