A building has to be maintained at 18°C at all times. A heat pump is required for this when the temperature outside the building drops to -6°C, thu building losses heat at the rate of 120000 kJ/kg. What is the least power required to drive the heat pump?
If a house needs a minimum heat transfer rate of 75 kJ/h (i.e., 75 kJ of heat needs to be transferred into the house during one hour) to maintain a pleasant indoor temperature. If one wants to use a heat pump with a COP of 5.55 to fulfill this heat transfer rate, what is the corresponding electricity (in kWh) consumption to run such a heat pump for one hour?
A freezer maintains a temperature of-30°C. The ambient air temperature is 20°C. If heat leaks into the freezer at the continuous rate of 3.15 kJ/s what should be the least power necessary to pump this heat out continuously?
an refrigeration system is used to maintain a space at temperature of 293k the space gained the heat at a rate of 5.56kw while heat produced in the space from the appliance is 2.22kw . if the system requires 3.11kw of electric power determine the cop of the system
A heat pump is used to extract heat from the outside atmosphere to heat the inside of a building. On a day when the outside air temperature is Tc°C, the heat pump is operating to a COP of 3.7, maintaining the inside temperature of the building at Th°C.
