ABSTRACT

The paper deals with experimental researches developed on a simulated condenser circuit of a ground coupled heat pump, in order to study a small- scale model of a ground heat exchanger and to obtain the necessary data to validate a model for dimensioning the horizontal ground heat exchanger of a ground coupled heat pump system which will provide the thermal energy for a  greenhouse.

KEYWORDS: ground coupled heat pump, ground heat exchanger, soil temperature, soil thermal conductivity, heat.
