Reversibleheat pumpsInnovative heating andcooling32675148910Apart from an efficient heat pumpheating system, summer time coolingof well-insulated new buildings isbecoming increasingly important toachieve a comfortable environment.Solar gain, higher levels of insulationand increasingly warm summertemperatures all lead to a risingdemand for cooling systems. Dimplexoffers an innovative, energy efficientconcept for all types of heat sourcesto also utilise water-bearing heatingsystems for cooling purposes.12345678910Heat pump manager for heating and coolingDynamic cooling via fan convectors with condensate drainage; suitable fordomestic buildings with high heat loads and commercial buildingsRoom thermostats switch from heating to cooling via an external signalfrom the cooling controllerSilent cooling utilising existing heating surfaces (underfloor, ceiling or wallcooling)Room climate control station for regulating the flow temperature with silentcooling via a reference roomUnderfloor heating for comfortable heat in the winterDew point monitor for connection to the cooling controller to interrupt thecooling operation of the system if condensate forms at vulnerable points inthe cooling distribution systemThe waste heat produced in cooling operation can be utilised for swimmingpool water heatingEfficient domestic hot water preparation utilising waste heat recovery incooling operationReversible air source heat pumps for outdoor installation36Reversible heat pumps

Byreversing this process the heat pump can be operated to providecooling, extracting heat from the building and transferring this to theenvironment via the heat pump refrigerant and compressor.Waste heat recovery makes it possible to also produce domestic hotwater extremely efficiently during the cooling process, while returningwaste heat to the ground (using a ground source heat pump)effectively stores the energy for use later in the year when needed forheating. The entire system is controlled by the heat pump manager.Passive cooling with borehole heat exchangers or groundwater.Deeper ground layers have constant temperature levels of around10°C all year round. This allows ground source heat pumps installedwith vertical borehole collectors to be used to provide ‘passive’cooling, by transferring excess heat from the building to the groundvia the collector in the summer months.This is achieved with the addition of a retro-fittable passivecooling unit, controlled by an additional cooling controller, whichcommunicates with the heat pump manager to enable a combinationof heating and ‘comfort’ cooling in a single system.Domestic hot water can still be provided in parallel to the coolingoperation as the heat pump compressor is not active in the passivecooling mode.Depending on the type of heating system installed in the building,cooling can be provided in one of two ways:Silent (active) cooling via surface heating systemsIn summer, the heating surfaces in floors, walls and ceilings areactivated for cooling by passing cooled water through them. Largecooled surfaces cool the rooms to a comfortable temperature withoutdraughts or air movement.Dynamic cooling via fan convectorsIntegrated ventilators guide the indoor air to a heat exchanger, whichheats or cools the air according to need. Multi-level controllable airrecirculation guarantees short response times and high transmissioncapacities.Reversible ground source heat pumpsModels available:5-11kW single phase (SI 5-11 TER)30kW three phase with heat recovery (SI 30 TER+)75kW three phase with heat recovery (SI 75 TER+)SI 75 TER+ SI 30 TER+ SI 5-11 MERPlease see technical specification pages for typical system configuration and accessories.Reversible heat pumps37
