WATER COOLER TRAINER-
'THE WATER COOLER' Test Rig enables students to study and understand Vapour Compression Cycle, its components, principle and working. All the components are mounted on rigid steel frame. The trainer consists of a hermetically sealed compressor, forced convection air‑cooled condenser, filter / drier, flow meter, expansion device and coil wound type evaporator. Separate pressure gauges are provided to record suction and discharge pressures and digital temperature indicators for various temperatures. The refrigerant used is R‑134 a which is environment friendly.
COOLING TOWER TEST RIG
Test Rig enables students to study and understand Cooling Tower, its components, principle and working. Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low‑grade heat from cooling water. The make‑up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling.
FINNED TUBE HEAT EXCHANGER APPARATUS-
Finned tube Heat exchanger is a device in which heat is transferred from one fluid to another. The apparatus consists of a concentric tube heat exchanger. Hot water flows through inner tube in one direction only and cold water flows through the outer tubes. Direction of cold fluid flow can be changed from parallel or counter to hot water so that unit can be operated as parallel or counter flow heat exchanger. Flow rates of hot and cold water are measured using Rota meters. A mono block pump is used to circulate the hot water from a re‑cycled type water tank, which is fitted with heaters and Digital Temperature Controller.
JOLTING TEST APPARATUS - AS PER IS 3144
“EIE Jolting test” methods are given for evaluating the settlement of thermal insulation materials. Like, Rockwool, glass wool, cerawool etc
UNSTEADY STATE HEAT TRANSFER APPARATUS-
To determine the internal thermal resistance of the body by calculating Biot number for solid Cylinder.
