An auditorium is to be maintained at a temperature of 26°C DBT and 50% RH. Air is to be supplied at a temperature not lower than 15°C DBT. The sensible heat gain is 110kW and the latent heat gain is 37.5 kW. Take the outdoor ventilating air as 25% by weight of the air from the room (meaning 75% of the airconditioned supply air is recirculated) and is at 35°C DBT and 60% RH. Determine the refrigerating load in Tons of Refrigeration (TR).

Someone proposes that the refrigeration system of a supermarket be overdesigned so that the entire air-conditioning needs of the store can be met by refrigerated air without installing any air-conditioning system. What do you think of this proposal?
Consider an office room that is being cooled adequately by a 12,000 Btu/h window air conditioner. Now it is decided to convert this room into a computer room by installing several computers, terminals, and printers with a total rated power of 8.4 kW. The facility has several 7000 Btu/h air conditioners in storage that can be installed to meet the additional cooling requirements. Assuming a usage factor of 0.4 (i.e., only 40 percent of the rated power will be consumed at any given time) and additional occupancy of seven people, each generating heat at a rate of 100 W, determine how many of these air conditioners need to be installed to the room.

A commercial refrigerator using R-134a as a refrigerant is used to keep the cooled environment at -35 C. The refrigerator releases the waste heat to the cooling water that enters the condenser at 18 C at 0.25 kg / s and leaves the condenser at 26 C. The refrigerant enters the condenser at a pressure of 1.2 MPa and a temperature of 50 ° C, and leaves the condenser at the same pressure, supercooled at 5 ° C.

Refrigerant R-134a enters the compressor of a refrigeration machine at 140 kPa pressure and -10°C temperature and exits at 1 MPa pressure. The volumetric flow of the refrigerant entering the compressor is 0.23 m3/minute. The refrigerant enters the throttling valve at 0.95 MPa pressure and 30°C, exiting the evaporator as saturated steam at -18°C. The adiabatic efficiency of the compressor is 78%.
