Sy Synbula JCU Homework Assignment #8 Drive (Problem 1) HW Assignments ENGR 217 SCARICA TUTTO Rome can get pretty hot in the mid-summer! Most of the Nome Cartelle air conditioning units in the Tiber campus use the working fluid R-134a (1,1,1,2-tetrafluoroethane), which is Solutions replaces the less environmentally-friendly R-12 of years File ago a)llustrate the following air conditioning cycle, indicating material, heat, and work flows, as well as given/known temperatures and pressures: R-134a is pressurized to 10.2 bar in an adiabatic, reversible compressor. This high-pressure, hot HW 6.pdf PO HW 1.pdf refrigerant is condensed outside of the building using ambient air to a saturated liquid state (there is no pressure loss in the condenser). The liquid is then throttled across a well-insulated valve to a pressure of 5.0 bar. Inside the building, room air is blown across an evaporator (no pressure loss), producing a PO HW 7.pdf saturated vapor of R-134a which is returned to the compressor Prova Drive gratis Coogle Drive è un posto sicuro per tutti i tugi f e Inizia oggi stesso. 107 PM Type here to search 6/3/2019 LEcture Slides Google Dr HW Assignmnts Gocgle Ghow to find work canstant C Gat Homawork Halp With x x ENGR 217 Google Drive G change in pressure and tem + X _ https://drive.google.com/drive/folders/1 t KvlbiuW1 - Mh_fBB-Wzcy7INI lj BMc C Apps Blaukboard Raidlerlirk S Symbula 1TiyF KE OYuuTute DIRECTV NOW JCU MY JCU ENCR 217- Guugle.. b)What are the temperatures (in °C) and specific Drive enthalpies (in kJ/kg) of the streams leaving the HW Assignments ENGR 217 condenser and evaporator, respectively?

Solutions d)The fluid exiting the compressor will be slightly superheated. What are its temperature (in °C) and File specific enthalpy (in kJ/kg), respectively? e)What is the specific heat duty for the condenser (the heat that must be dumped to the outside air), in kJ/kg? f) The throttling valve will produce a mixture of liquid and vapor R-134a. What are this stream's specific HW 6.pdf PO HW 1.pdf enthalpy (in kl/kg) and quality? g) What is the specific heat duty of the evaporator (the heat absorbed from inside the room), in kJ/kg? h)The unit is expected to process about 3 kg/min of air, which enters the evaporator at 27°C and exits at 19°C.
