fOne question but divided into sub connected questions * Question Completion Status: QUESTION 1 20 points Save Ans The heat-pump system shown is designed to provide water-heating and space-cooling. The system includes a heat exchanger to subcool the R134a refrigerant at the outlet of the water heater while heating the refrigerant at the outlet of the evaporator. Given the following data, determine the enthalpy at each station, 1 through 6, using the R134a property tables (click here). Type your answers...
PLEASE ANSWER QUICKLY!! I WILL THUMBS UP! Thank you so much in advance!! Neatly sketch the complete heat-pump cycle from Question 1 on a P-h diagram, showing clearly all six processes (1) - (2) - (3) - (4) - (5) - (6)-(1). If you have a printer available, you may print this PDF file of the R134a P-h diagram. Otherwise, draw a very neat scale copy of the P-h diagram shown below. You do not have to type any response...
