Microtech Engineering

The unit is useful to calculate Actual COP, Theoretical COP, Carnot COP & heat transfer co-efficient in evaporator and also demonstrates use of controls in refrigeration cycle. A hermetically sealed compressor using R-12 refrigerant, air-cooled condenser, evaporator with water as medium & Heater, Rotameter for flow measurement, thermostatic expansion valve with solenoid valve.

The unit demonstrates super conductivity of heat pipe as compared to copper pipe as good conductor of heat and to stainless steel pipe as same material of construction. The unit provides Heat pipe, copper pipe & stainless steel pipe. All the pipes are heated at one end & water tank at other end. To find out isothermal operation of heat pipe as compared to other conductors by using thermocouples.

The unit is useful to study of year round air conditioning .A duct fitted with cooling coil, heaters and steam humidifier, to simulate summer or winter conditions, simulating conditioning section using cooling coil, heaters and steam humidifier connection. Various measurements for cooling cycle, preheater & reheater.Axial flow fan to generate the air flow

The unit is useful to study principals of recirculation. A small room under test. Unit consists hermetic compressor, air cooled condenser, expansion valve, direct expansion cooling coil, preheater and reheater arrangement to recirculate the air partially or fully. Air by blower & controlled by butterfly valve.
