Disadvantages of vapor compression refrigeration system include potential leaks of refrigerant gases, environmental impact of fluorinated gases, energy consumption for compression, and complexity of maintenance and repairs.

The compression sack for my sleeping bag did not work well.

The relationship between isentropic compression work and the efficiency of a thermodynamic process is that the efficiency of a process increases as the isentropic compression work decreases. Isentropic compression work is the work required to compress a gas without any heat transfer or energy loss, and a lower amount of this work indicates a more efficient process.

In case of vapour compression cycle (VCC) the COP is given by (desired effect / work input). in the other words it can be defines as what we want and what we are paying for that... so in VCC the paying amount is very less as due to low temperature difference that why its value is more than 1. but in case of vapour absorption system the COP is given by (heat taken by evaporator/ heat given to generator). the heat input taken by evaporator is less as compared to heat given to generator.. that why its COP is less than 1......
