A comparison of alternative heat pump systems for use in South African climatic conditions is undertaken in this paper. Monthly heating/cooling capacities and coefficients of performance for air-source and vertical and horizontal ground-source systems have been calculated. The desired type of heat exchanger is determined by considering economic factors and the cost-effectiveness of investments of...
The economical viability of horizontal-ground-source systems is compared to air-source systems in South Africa in this work. This study is undertaken because South African manufacturers of air-source systems are considering producing ground-source systems, since the latter systems are gaining more acceptance for environmental reasons. Monthly heating/cooling capacities and coefficients of performance...
