The steam engine is supplied with steam from a steam header at a reduced pressure via an overspeed trip solenoid valve and a displacement lubricator from which oil is displaced by droplets of condensed steam into the steam supply to lubricate the engine. Steam Engine Steam Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting hack panel and adjustable feet. Engine inlet and outlet steam pressures are indicated on 0-16 bar and -1 to 3 bar Bourdon tube pressure gauges respectively. A control cubicle surmounted by resistive load elements within a separate ventilated enclosure, contains electrical control circuits and is fitted with the control switches and the indicating instruments for engine speed, dynamometer output current and voltage and analogue temperatures which can be selected by an associated multi-position switch. The steam bench comprises a robust single cylinder, double acting reciprocating steam engine driving a dynamometer which enables a calculable, variable resistive load to be easily imposed on the engine. Exhaust steam is cooled by a water cooled, coiled tube type condenser.

The Recirculating Air Conditioning Unit incorporates wheels for its mobility. Recirculating Air Conditioning Unit mounted on an anodized aluminum structure and panels of painted steel.
Main metallic elements of stainless steel.
2 Electrical heating elements, computer controlled: one of 2000W (pre-heater) at the inlet of the evaporator and other of 1000W (re-heater) at the outlet of the evaporator.
Axial fan, with speed control from computer, 2500 r.p.m., maximum flow: 2160 m3/h.
Evaporator.
Diagram in the front panel with similar distribution to the elements in the real unit.
Tunnel made of stainless steel of 300 x 300 x 4000 mm., in which there has been installed 4 windows of 200 x 300 mm. to visualize the tunnel inside.
Condenser unit, composed by:
Air flow 900 m3/h.
High-pressure cut-out, regulated at 14 bar. It switch off the compressor when the pressure reach the fix pressure.
Condenser, 1591BTU's.
Compressor, computer controlled, 1/2 Cv, 4.48 A.
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. Recirculation Air Conditioning Unit With Climatic Chamber is a recirculating air conditioning unit with transparent windows and a climatic chamber. 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. 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 amount of air recirculation is controlled by ventilation flaps. Steam generator, compressor and condenser are underneath the duct.
Experiments:
Demonstration of preheating, cooling and dehumidification, humidification, reheating, and mixing processes on psychrometric chart.
Demonstration of refrigeration cycle on Pressure-Enthalpy diagram of the refrigerant.
Determination of recirculating and mixing process of moist air.
