High-efficiency water-to-water heat pumps with stainless steel coil heat exchanger Energy from the ground water Pure energy efficiency Water-to-water heat pumps extract the thermal energy stored in The new high-efficiency heat pumps are equipped with a the ground water for heating the building. Two wells are drilled newly-developed compressor design, a COP booster and an in the direction of the water flow, and the water is fed through electronic expansion valve. The newly-developed COP booster the heat pump. Ground water temperatures remain constant all combines the functions of the economiser with the functions of year round, ensuring that water-to-water heat pumps operate in the liquid separator, thus protecting the compressor from liquid an extremely efficient and thus environmentally friendly way. refrigerant. This allows the refrigerant circuit to be operated at a Special attention must be paid to the water quality and available lower temperature level, which means a significant increase in volume, as ground water is an efficient but sensitive source of With the extremely robust stainless steel coil heat exchanger, the ground water heat source can be utilised directly. The normally required intermediate circuit, which negatively affects the operating costs, is omitted in this design.

High-efficiency water-to-water heat pumps in universal design COP booster for maximum COPs during operation through minimal overheating Maximum flow temperatures of 62 °C for high domestic hot water temperatures Direct utilisation of the ground water heat source via stainless steel coil heat exchanger Free-swinging compressor baseplate with solid-borne noise insulation for less acoustic emissions - direct connection to the heating system possible WPM EconPlus heat pump manager for controlling an electronic expansion valve for high seasonal performance factors and low operating costs Heat pump...
