Gas Refrigeration Systems Are Used In

The first gas absorption refrigeration system using gaseous ammonia dissolved in water referred to as aqua ammonia was developed by ferdinand carré of france in 1859 and patented in 1860.

Gas refrigeration systems are used in. For example residential hvac chillers often use ammonia as the refrigerant and water as the absorbent. The cold air can be directly used for refrigeration. It is useful in aircraft refrigeration at high altitude. Unlike mechanical compression refrigeration systems which typically use r 22 and r 410a for refrigerants absorption refrigeration systems use refrigerants that other substances are attracted to and absorb.

So gas refrigeration is preferred in applications such as aircraft air conditioning systems. When the gas is throttled from very high pressure to low pressure in the throttling valve its temperature reduces suddenly while its enthalpy remains constant. The water is located in a. There would be no significant change in the performance of air refrigeration if it is operated much away from its design conditions.

Carl von linde an engineer specializing in steam locomotives and professor of engineering at the technological university of munich in germany began researching refrigeration in the 1860s and 1870s in. The gas refrigeration system is a. This principle is used in gas refrigeration system. Less heavy and bulky than the vapour compression cycle c.

None of the above view answer hide answer. Just as the vapors are used for cooling in the vapor compression cycle and vapor absorption cycle the gas is used for cooling in gas refrigeration cycle. There is no phase change liquid gas during the operation of the system. More heavy and bulky than the vapour compression cycle b.
