  3. cold medium hot Winter The heat pump transforms the heat energy to a usable level between 25 and 45 °C. By means of air convectors, the greenhouse air gets heated up. By means of black collector pipes (solar thermal collector in the pediment of the greenhouse) heat is collected by absorbing sunlight. +10 to +12 °C +25 to +45 °C Floor heating in the flower / vegetable beds ensure a very efficient low-loss heating of the plants. The carrier medium is heated up to an inlet temperature of +10 to +12 °C The carrier medium is water or brine (for frost protection) If there is the requirement for cooling in the neighborhood (data centre, production process), cold carrier medium can be provided well water waterfrom groundcollector or Heat can be provided to low temperature consumers (such as floor heating for homes and office buildings, swimming pools, or air heating systems in production facilities).

  4. cold medium hot Summer a) Natural / Passive Cooling or b) The heat pump transforms the cooling energy to a higher level. By means of air convectors, the heat energy gets removed from the air. By means of black collector pipes (solar thermal collector in the pediment of the greenhouse) heat is collected by absorbing sunlight. +10 to +12 °C In case of warm days and cold nights: the underground could be used as energy storage. The carrier medium is reduced to an inlet temperature of +10 to +12 °C Cooling can be provided to external consumers (office building, …). well water waterfrom groundcollector or To improve carbon footprint: Heat can be provided to low temperature consumers (swimming pools, showers, hot process water).

  5. By switching valves of the heat pump many of the following functionscan be used in parallel: - Natural / Passive Cooling (heat pump switched off) - Active Cooling (heat pump in operation) - Transformation of specific heat (heat removed from greenhouse could be used elsewhere) - Heat recovery on external sources / consumers - Highly efficiency air conditioning - Low temperature heat pump (LTHP)

  6. Efficiency:The term coefficient of performance (COP) is used to describe the ratio of useful heat movement to energy input. AccordingtolayoutdatafromBitzer

  7. Monitoring The PLC can be equipped with remote maintenance / diagnosis (teleservice) functions.

  8. Examples 800 kW heat output capacity 1400 kW heat output capacity 2 x 300 kW heat output capacity 7 x 300 kW heat output capacity
