Definitions

• the present invention is related to a system for balanced regulation of indoor temperature, especially adapted for living quarters (15) in smaller buildings.
• the desired temperature set for specific rooms in the building is the basis.
• the need for heat supply will depend on heat losses and heat supplies. Many parameters participate in the balance of energy and will more or less influence the need for increasing or decreasing the supply of energy or even removal of energy from the rooms. Energy will for example be supplied from people in the rooms when being in activity. Furthermore energy also will be supplied from the energy losses to the surrounding air from a hot water boiler and to a certain extent also from other electrical devices. Heat losses to the surroundings on the other hand will occur through walls and other structural parts as well as windows and doors. Other well known losses are airing and ventilation.
• losses may be minimized by heat exchange, for air as well as for water, such as the heat in the air from the ventilation system and from draining of water and sewer.
• figure 1 a flow chart connecting the 5 different units in the system according to the present invention
• figure 2 discloses schematically a vertical section through a house with the units.
• the system according to the present invention comprises three basic units, a heat pump aggregate 16, a vent heat o exchanger 6 and a water discharge heat exchanger 7.
• the aggregate 16 simultaneously is a combined air filter and air heating unit for recycled air to and from the rooms in question.
• a piping circuit 22 is connecting the different units. Heat may optionally be stored in an accumulator 8.
• a control panel 20 is monitoring the system based on a set desired temperature.
• the aggregate 16 comprises a pump 12 for the con ⁇ tinuously circulating medium in the piping circuit 22, said medium thereby being a fluid, as such a liquid or preferably a
• the medium is conducted to a condensator 4, exchanging heat to the circulating air in the aggregate 16.
• the air from the aggregate 16 is discharges by a fan 5 to the rooms of the house, the living or office quarters
• the medium is conducted to a heat exchanger 3 through a throttle organ 13 where the medium evaporates and absorbs heat from the system whereafter the evaporated medium is conducted to the compressor 1 where the cycle is repeated.
• the system may be reversed by a reversing valve 19 whereby the aggregate 16 delivers cooled air.
• the reversing valve 19 may be remotely operated from the control panel.
• the condensator or radiator 4 is especially adapted to absorb all variations of effect as a consequence of larger temperature differences in the circulating medium.
• the aggregate 16 is constructed as a container enclo ⁇ sing the compressor 1, the first heat exchanger 2, the condenser 4, the evaporator 3 as well as the pump 12 and the fan 5 as well s as the reversing valve 19 and the throttle organ 13.
• a filter 10 is arranged, through which circulation air is vented by the fan 5, which air is heated by the condenser 4 and all other units, before leaving the aggregate 16 through a warm air duct 23 to the living quarters. o The air is vented from the living quarters to the aggregate 16 whereby the recirculated air is cleaned in the filter 10.
• the vent heat exchanger 6 exchanges heat from air before being let out to the outside of the quarters 15. Air from bathrooms as well as the living quarters generally is conducted s to the exchanger 6.
• the vent heat exchanger 6 comprises a safety filter 18 for filtering specificly the air from rooms with high moisture content, before the air, together with the air from other rooms is heat exchanged with the medium being pumped by the pump 12 in the aggregate 16. Air is vented through the exchanger 6 by a fan 14 inside the exchanger 6.
• the water discharge heat exchanger 7 receives all water drained 24 from the quarter, such as bath rooms, kitchen, toilets as well as the sewers from, the medium is pumped through the system by the pump 12, assuming heat from the drainage water before it leaves the housing.
• An accumulator 8 is connected to the piping circuit 22 for storing and distributing the energy to the medium.
• the accumulator is preferably placed outdoor in the ground or in an isolated version even indoor. Temperature differences occurring between the accumulator 8, the vent heat exchanger 6 and the water heat exchanger 7 maintain the system automatically by the aggregate pump 12, the aggregate fan 5 and the air heat exchanger fan 14, thereby transferring energy to the quarters or to the accumulator 8.
• An element 21 for peak load securement being connected to the piping circuit 22 between the water heat exchanger 7 and the accumulator 8. This element ensures that maximum effect is maintained from the system even during cold periods, thereby also providing a system safety in case of freezing periods down to minus 12 °C.
• the system according to the present invention provides a unique ability to optimize energy consumption for a housing, building etc, with a minimum of components and controls.
• the system is most reliable in operation as it comprises only few part exposed to wear.
• the system is well adapted to extract heat from the ground by a collector 24 being connected by the piping circuit in parallel with the accumulator 8 or replacing the accumulator.
• the collector 24 may extending downwardly in a bore hole to a dept of for example 90 meters.
