Design of a ground source heat pump.

The house can be heated by a resister heater, a heat pump, or a ground source heat pump system Design of a ground source heat pump system for house heating. Among these systems, the ground source heat pump is the most energy efficient heating system. Please describe the heat pump system for a house that needs 150 M BTU each day if room temperature is set at 20 °C. The design of the system should focus on the design of the system collecting the heat from the ground with a temperature of 12 °C. The calculation should include the flow rate of fluid, inlet and exit temperature, and energy consumption for the flow of fluid in the circulation pipe. You can use either air or water as working fluid. In the report, you need compare the benefit of the ground source heat pump including utility bill and GHG emissions associated with electricity.

Answer 1

Let consider these ground heat pump works on Reversible heat pump cycle. Then Cop = T_H/T_H - T_L = 293/293 - 285 (COP)_connect HP = 36.665 But actual COP ranges from 3 to 6 lets consider 4.4 = CO_Pact therefore CO_Pact = 0.12 times 86.66. = Q_Higher/Q_high - Q_lower 4.4 = Q_h/m^dot middot W_net Q_h = 150 METU = 150000 BTU/hr = 4.375 KW. = 150000 times 24 each day Q_h = 105 KW therefore Power = 105/4.4 = 23.36 KW m^dot middot W_net = 23.36 KN (nearly) (i) Air source heat pumps are more efficient than heating by pure electric heater (ii) Its setup cost is higher than conventional one but more energy saving will be there. (iii) These heat pump offers emission reduction potentials since electricity produce by renewable sources. (iv) for calculation of
