Geothermal Heat Pump for a Zurich House
摘要
Heat can be transferred between the ground and built environments through ground source heat pumps consisting of primary and secondary circuits. The primary and secondary circuits include a ground heat exchanger and the built environment that can be heated or cooled, respectively (Fig. 4.1). Machines with electrical drives, namely, heat pumps, are applied between the mentioned circuits to raise the temperature from 12–15 °C to 45–50 °C to heat the superstructures [1].
