Question:
Consider an air-conditioning unit in your home operating in heating mode during cold months in Melbourne (i.e., June-September). The unit is used to maintain the indoor
temperature at a comfort level (your reasonable assumption). How much can be saved on electricity cost during this period (roughly), if the system is converted to a ground
source heat pump?
Assume the following ones and make any other assumptions as required to answer this
question:
• The power of the heat pump unit
• Number of operating hours per day
• Your comfort temperature level
• Average outside temperatures for months June to Sept., during the hours that the
unit operates
• Cost of electricity (per kWh) on your contract
• Keep the cost of system’s alteration outside your calculations
