Buildings

Simultaneous Heating & Cooling

With correct integration of the heat pump in the overall energy system of large-volume buildings, simultaneous heating and cooling can be achieved for maximum efficiency.

  • Large-volume building heating & air conditioning of office buildings, residential buildings, office buildings, schools, hospitals, supermarkets, warehouses, production facilities, etc.
  • Hospitality & sports facilities heating for space heating, swimming pool heating, water heating, air conditioning. Short amortization periods because of the constantly high heating and heat demand
  • Agriculture heated greenhouses or ponds for fish farming
  • Infrastructure-icing of roads, railway tracks, concrete runways, lawn and sports fields and much more…

Heating and Cooling 

Instead of using a fuel boiler to produce heat and a separate parallel chiller for cooling, the OCHSNER heat pump can perform both functions ( heating and cooling) simultaneously or consecutively. In this case, the result is lower investment costs and unbeatable high energy efficiencies with unbeatable low operating costs.

Ground Sun work closely with OCHSNER to ensure an optimally functioning heat pump is designed, installed and operated. A correct interpretation of the heat source and heat sink is paramount and ensures reliable operation and low operating costs.
