A new design approach for ground source heat pumps based on hourly load simulations

Abstract

Most design programs for heat exchangers design for Groundsource heat pumps use a superposition of annual, monthly and hourly pulses. Some design methods use monthly and hourly loads. Hourly load simulations are used mostly for simulation purposes but not for design due to longer simulation time. The authors propose a new design approach based on hourly load data with the aid of an accelerated algorithm. The new approach does not use aggregation of loads and simulate the real thermal response of the individual hourly loads.
