Advanced heat recovery and air conditioning heat pump in a hospital.

Author(s) : MINEA V.

Summary

The configuration and some in-field performance data for an original exhaust-air heat pump for heat recovery and air conditioning, developed and tested in a retrofitted ventilation system in an hospital, are presented in the paper. The heat recovery system was designed to reduce fossil fuel consumption for heating, and its negative environmental effects, and to improve internal air quality and medical comfort. The concept includes two stages for preheating outdoor air, respectively a typical glycol-to-air heat exchanger and a split-type, reversible air-to-air heat pump between the hospital's outdoor and exhaust air-streams. The heat pump prototype consists of two independent refrigerating circuits. The system was monitored over a 12-month period, and the results presented focus on the main thermodynamic parameters, seasonal performance factors, and annual energy savings.
