Study of the most suitable operation of ground source heat pump system for totally electrified heating and cooling system : - A practical example in a hospital -

Abstract

This paper indicates a heat source system which is installed in a totally electrified hospital built in April 2008. The heat source system consists of a high efficient screw type heat pump chiller with ice storage and another module type air cooled heat pumps. A ground source heat pump system is also introduced by using the foundation piles as ground heat exchangers. In this paper, seasonal and daily operation modes of the system are investigated. Measures for high efficient operation and energy saving in the whole system are finally proposed.
