The design of a simple refrigerant condenser has been proposed for opment. The condenser will accept hot, high pressure saturated type R-134a from a compressor to reject its heat to ambient air at standard mospheric conditions. The cooled refrigerant is drained back to an evaporation through an expansion valve to complete a standard refrigeration cycle. The design Concept will be to use bare 3/8-in. Outer diameter tubes arranged staggered tube bank. To simplify the design, there will be only one tube and one tube outlet into and out of the bank, respectively. No front end or rear end headers will be considered. It is hoped that the pressure drop a tube bank will be kept as low as possible to ensure the smallest possible fan size. The System will operate under the following conditions.
(i) Four rows of tubes
(ii) Sixteen tubes per row
(iii) Width is 32 in.
(iv) Entering air temperature is 95degreeF
(v) Coil face velocity is not to exceed 700 ft/min
(vi) R-134a enters at a saturation pressure of 200 psia (assume liquid phase) Determine the heat rejected by the Condenser and the temperature of the
