| welcome to our company ! |

Rather than theory teaching, actual practicals in laboratory plays an important role to train the students perfectly. Therefore, we ‘J. P. TECHNO INSTRUMENTS' started a new venture in this field.
We set upped our unit in rural area i.e. just 14 Km. from karad which is in National Highway No.4. Karad is a well-known place for all types of education institutions.............read more |

|
| |
‘JPTI’ make Refrigeration Test Rig enables students to study and understand Vapour Compression Cycle, its components, principle and working. All the compo nents are mounted on rigid steel frame.
The trainer consists of a hermetically sealed compressor, forced air-cooled condenser, fitter/drier, rotameter, expansion device and immersed tube type evaporator. Separate pressure gauges are provided to record suction
and discharge pressure and digital temperature indicators for various temperatures.
The refrigerant used is R-134 a which is environment friendly. |

The ‘J.P.T.I.’unit consist of a 1.5 m. long rectangular duct at the centre of which a cool ing coil fitted. A fan drives air over the finned tube cooling in the duct. The refrigerant supply to this cooling coil is achieved through compressor condenser circuit fitted at the base of the table platform. Pressure temperature, flow of refrigerant etc. like this measurements can be achieved at different locations in refrigerant circuit. Thermom eters are provided to measure dry bulb and wet bulb temperature of inlet and outlet air.
Anemometer for measurement of air flow rate. The duct is insulated with glass wool on all four sides. |

JPTI’ unit works on vapour compression principle and uses R-134 a as a refrigerant. It is environment friendly and approved under Montreal Protocol. The brine solution is stored in S.S. / fiber coated tank. Ice cans placed in this tank. The stirrer motor is pro vided to agitate the solution and to increase the heat transfer coefficient. All the compo nents are mounted such that its operation and working can be easily understood. The required controls for temperature, pressure , and overload are provided. |

Domestic Refrigerator Test Rig |
| |
|
| |
The ‘J.P.T.I’ unit consists of a unit enables to study the various parameters affecting the performance of a domestic refrigerator. It consists of refrigeration cycle of domes tic refrigerator. It consists a hermetically sealed compressor, air cooled condenser, capillary tube & a natural convection type evaporator. The evaporator is fitted with a small heater to stimulate different load conditions various measurements are pro vided so that power consumption, cop, theoretical & actual refrigerating effects refrig erant flow rate & effect of door opening on power consumption can be studied & also students can visualise automatic operation of unit using a thermostat. |
