GENERAL CYCLE AIR CONDITIONING TEST RIG - Naugra Lab

GENERAL CYCLE AIR CONDITIONING TEST RIG
NaugraLabs Laboratory Product Name: GENERAL CYCLE AIR CONDITIONING TEST RIG
NaugraLabs Laboratory Product Code: REFIAC0003

Description and Specification for Lab Tenders

GENERAL CYCLE AIR CONDITIONING TEST RIG.
PRODUCT DESCRIPTION:
The A.C. test rig works on simple vapour compression refrigeration cycle using R-134a as a refrigerant. The system is fabricated such that student can study all the air conditioning processes. It is also useful to understand working of all the components of system, their performance and control etc.
All the components are mounted on the display board, so that students can observe their working easily.
