MEASUREMENTS OF HP COP AND HP THERMAL BALANCE
1. Record the operating parameters for the heat pump operating cycle for the set temperature of DHW in the storage tank (amount of heat transferred to the storage tank and to the buffer tank, amount of electricity consumed). Record the temperature of the outdoor air. Calculate the Coefficient Of Performance for your measurement. Assume the heat pump supply temperature at 60 ° C.
2. Using the wing anemometer, measure the air velocity in the intake channel. Having a given channel cross-section area, calculate the flow of the evaporator’s suppling air.
Record the inlet and outlet air temperatures and humidity. Record the length of the heat pump operation cycle for which the measurement was made. From the i-x graph read the enthalpy of the inlet and outlet air. Calculate the heat output of the evaporator and estimate the amount of renewable energy gained from atmospheric air.
3. Write the energy balance equation for the measurement.
4. Create the COP characteristics of the heat pump (COP against external air temperature) and insert the COP calculated from the measurements.
CALCULATION OF THE COP BASED ON ARCHIVAL DATA
1. For the received archive data, calculate the energy efficiency of the heat pump.
2. Make a graph of the COP dependence on the supply air temperature of the evaporator (outside air temperature). Compare your graph with manufacturer characteristics.
3. Make a graph of the heat pump's supply temperature against the outside air temperature.
