Question: Consider the refrigeration cycle and the heat pump cycle. What is the main difference? The drinking water needs of a production facility with 20 employees is to be met by a bubbler type water fountain. The refrigerated water fountain is to cool water from 22 to 8°C and supply cold water at a rate of 0.4 L per hour per person.
(b) If one is a refrigeration cycle and the other is a heat Two reversible cycles operate between hot and cold reservoirs at temperature TH and TC, respectively. (a) If one is a power cycle and the other is a heat pump cycle, what is the relation between the coefficient of performance of the heat pump cycle and the thermal efficiency of the ...
11-41 A heat pump operates on the ideal vapor-compression refrigeration cycle and uses refrigerant- 134 a as the working fluid. The condenser operates at 1000 kPa and the evaporator at 200 kPa. Determine this system's COP and the rate of heat supplied to the evaporator when the compressor consumes 6 kW.
A heat pump operates on the ideal vapor compression refrigeration cycle with R-134a as the working fluid between the pressure limits of 0.32 MPa and 1.4 MPa. If the mass flow rate of the refrigerant is 0.25 kg/s, the rate of heat supply by the heat pump to the heated space is (a) 7.6 kW (b) 31 kW (c) 26 kW (d) 39 kW (e) 49 kW 5.
A heat pump operates on the ideal vapor-compression refrigeration cycle with R-134a as the working fluid between the pressure limits of 0.32 and 1.2 MPa.

6. Consider a heat pump that operates on the ideal vapor compression refrigeration cycle with R- 134a as the working fluid between the pressure limits of 0.32 MPa and 1.4 MPa. The coefficient of performance of this heat pump is (a) 0.80 (b) 1.2 (c) 6.2 (d) 4.1 (e) 5.1 7.
Explain the following types of cycles: power cycle, refrigeration cycle, and heat pump cycle. Also, give the information (formulas) of thermal efficiency and coefficient performance for the cycles. There are 3 steps to solve this one.
Consider a heat pump that operates on the ideal vapor-compression refrigeration cycle with R-134a as the working fluid between the pressure limits of 0.24 and 1.2 MPa. Using the closest value in your textbook R-134a Tables, which makes the result somewhat inaccurate, the coefficient of performance of this heat pump is (do not interpolate, pick ...
A heat pump operates on the ideal vapor-compression refrigeration cycle with R-134a as the working fluid. This heat pump is used to keep a space at 22 °C by absorbing heat at a rate of 3.345 Btu/s from geothermal water flowing through the evaporator heat exchanger. The evaporator operates at 70 °F, and the condenser pressure is 140 psia.
