Heat Pumps for Heating and Cooling reversing valve could be a complicated process. It needs a very skilled person. If you really need to replace your valve, and your unit is over 10 years of age, please consider replacing the Heat Pump. The heat pump reversing valve might cost $200-$250. − Note that the reversing valve is energized or de-energized based on the manufacturer’s specification to direct the flow of refrigerant to the appropriate coils. Do all heat pump systems have reversing valves? No. Heat pumps that are intended to provide both heating and cooling are equipped with reversing valves. However, heat pump systems that are intended to provide only heating are not equipped with reversing valves. 1.7. • Thermal Performance Terms A Btu/h, or British thermal unit per hour − A Btu/h, or British thermal unit per hour, is a unit used to measure the heat output of a heating system. One kWh of heat = 3414 Btu/h. A ton is a measure of heat pump capacity. It is equivalent to 3.5 kW or 12 000 Btu/h. Heating degree-days − Heating degree-days is a measure of the severity of the weather. One degree-day is counted for every degree that the average daily temperature is below the base temperature of 18°C. For example, if the average temperature on a particular day was 12°C, six degree-days would be credited to that day. The annual total is calculated by simply adding the daily totals. The coefficient of performance (COP) − The performance of heat pumps is indicated by the coefficient of performance (COP). It measures the amount of heat energy moved (in watts), divided by the electric energy used to move it (also in watts), at a given outdoor temperature. Higher COP values indicate a more efficient system. An electric resistance • • 11PDF Image | Heat Pumps for Heating and Cooling
