A heat pump with refrigerant-134a (R-134a) as the working fluid is used to keep a space at 21 °C by absorbing heat from geothermal water that enters the evaporator at Ti,water = 60 °C at a rate of 0.067 kg/s and leaves at To,water = 40 °C. The specific heat of liquid water is 4.18 kJ/(kg∙K). Refrigerant enters the evaporator at TR-134a = 10 °C with a quality of x = 12 % and leaves at the same pressure as saturated R-134a vapor at the same temperature. The compressor consumes 1.4 kW of power. 1)Determine the mass flow rate (in kg/s) of the refrigerant. 2)Determine the rate of heat (in kW) supplied to the space. 2)Determine the COP of the heat pump. 4)Determine the ideal minimum power input (in kW) to the compressor for the same rate of heat supply
Find out the COP of a Carnot heat pump operating between temperatures 6o C and 37o C.
- The heat pump with a power input of 2000 kW draws heat from a heat source at 70 ° C and gives heat to a boiler. Thanks to the heat given to the boiler, the saturated liquid water entering the boiler at 300 kPa pressure leaves the boiler as saturated steam at 300 kPa (3bar) pressure. Since the performance of the heat pump (γ = COP_IP) is equal to 0.5 times the performance of the Carnot heat pump operating under the same temperature conditions, find the mass flow rate (kg / s) of the water flowing from the boiler. Note: The boiler works according to the open system SASA model. Changes in kinetic and potential energies for the boiler are negligible.
