The solution circuit in vapour-absorption cycle comprises of
In vapour-absorption cycle, the system formed by the generator-valve-absorber-pump may be considered to represent the heat engine part of the cycle. In this part, only the refrigerant- absorbent solution circulates. This part is known as solution circuit.
The refrigerant circuit in vapour-absorption cycle consists of
The vapour compression refrigeration cycle is an inherently irreversible cycle, because
In vapour compression refrigeration system, at entrance to which component the working fluid is superheat vapour?
Which one of the following expansion processes takes place in a vapour compression cycle?
The primary purpose of Boot-strap system is to
Boot-strap system: It has two heat exchanges ' instead of one and the expansion turbine drives a compressor rather than a fan. So, it cannot be used for ground cooling. The primary purpose of the Boot-strap system is to provide an additional cooling capacity when the primary source of air does not have a sufficiently high pressure to provide the amount of cooling required. The turbine drives the secondary compressor to raise the pressure of primary air before it enters the turbine.
The air cooling system mostly used in transport type aircrafts is
In a boot-strap air evaporative cooling system, the evaporator is provided
Boot-strap air evaporative cooling system is similar to boot-strap air cycle system except that the addition of an evaporator between the second heat exchanger and the cooling turbine.
The cooling system used for supersonic aircrafts and rockets is
The regenerative air cooling system is a modification of simple air system with the addition of a secondary heat exchanger in which the air from the primary heat exchanger is further cooled with a portion of the refrigerated air bled after expansion in the turbine.
Dry ice is suitable for ____ temperature refrigeration.
Dry ice when exposed to atmosphere sublimates by absorbing latent heat of sublimation.
