Problem 7-10 A small football promotion office is being designed for Jacksonville, Florida. The design heating and cooling loads are 61,200 and 55,400Btu/h, respectively, based on 99.6% and 1% outdoor design dry-bulb temperatures. Balance point has been estimated as 65F. 1. Select an appropriate heat pump from the XYZ Corporation models listed on page 278 and estimate the energy costs for summer and winter if electricity is 8//kWh. These heat pumps are being provided at a very low cost because they have relatively low SEERs (10-11). The current (2019) required SEER is 14.0. An example of the performance of a heat pump with a SEER of 14.0 is given below: 2. Compare the heating energy cost for the heat pump to that for a condensing gas furnace with natural gas costing $1.20 per therm
