3. HGCHP system with cooling tower as supplemental heat rejecter
As mentioned, when the GCHP system is utilized for cooling load dominated buildings, the heat rejected into ground will accumulate around the ground heat exchangers, which results in degradation of system BRL 50481 performance. One of the available options to resolve this problem is vascular parenchyma to utilize hybrid GCHP systems to reject the accumulated heat by supplemental heat rejecters. The scope of Section 3 is limited to the HGCHP system with supplemental heat rejecter for cooling load dominated buildings. The conventional supplemental heat rejecter of the HGCHP system is a cooling tower. As shown in Fig. 6, the conventional HGCHP system mainly consists of a heat pump unit, a GHE, a cooling tower, a plate heat exchanger and a domestic hot water (DHW) production device.
