1st Step: Evaluate the performance of the Refrigerator 1.Refrigerator 1 operates as a reverse Carnot cycle using R-717 as the refrigerant at aflow of 1.8 kg/s. The condensing and evaporating temperatures are 25 °C and -5 °C, respectively.To evaluate the performance of Chiller 1, you must determine the following performance parameters:project:a) Rate of heat elimination in the condenser (Q );b) The power of the compressor;c) The COP of the cycle.For the energy balance, make the following considerations:- Permanent regime;- Variation of kinetic energy and potentials are negligible;- Compressor and turbine operate adiabatically;- Evaporation and condensation steps do not involve work. Please, make it typeable, written in virtual text, do not do it by hand and do not take a photo, it interferes with the understanding of the lyrics.
3.5 An ammonia refrigeration system operates between saturated suction temperature of -20°C, and saturated discharge temperature of +40°C. Com- pare the COP of the cycle using wet compression with that of the cycle using dry compression. Assume that the vapour leaving the compressor is saturated in the case of wet compression, and the vapour entering the compressor is saturated in the case of dry compression. The refrigerant leaves the condenser as saturated liquid.

Question-3As seen in the figure, the stable air conditioner keeps the indoor environment at 21oC while the outdoor environment is 32oC. Since the heat transfer rate from the roof and walls to the house is 31,650 kJ/h, is the 2.2 kW power input to the compressor of the air conditioner sufficient? If sufficient, calculate COP, if not, find the theoretical minimum power in kW
