AIR HEAT PUMP OUTDOOR HOUSING ARRANGEMENT FOR IMPROVING EQUIPMENT USE AND DRAINING AND DRAINING THE BUILDING SPACE IN THE BUILDING.

FIELD OF THE INVENTION

The invention relates to an additional apparatus for an outdoor unit of an air heat pump connected to any crawl space house. The idea is to install a heat pump that takes in heat from the air in an insulated modular enclosure, with a piping system that improves the efficiency of the heat pump by utilizing air ducts leading to the creep space. At the same time, it solves the problem of freezing of condensation water and the humidity, radon and ventilation problems of the building's crawl space.

BACKGROUND AND ASPECTS OF THE INVENTION

The idea behind the innovation is to install the outdoor unit of the air heat pump transversely to the house, to cover it and to encase it on the walls, which can be conveniently supplied to the outdoor unit by opening the adjustable airways. The structures in question are made of airtight thermal insulation boards, a frame made of profile posts, a solid insulated subfloor and waterproof roofing material. Pipes are led from the housing to an isolated crawl space in the house. The air passing through the outdoor unit can be partially or completely circulated through the crawl space. As an insulated structure, the base plinths have frost temperatures as well, as warm air is blown from the crawl space, if necessary. The air circulation of the enclosure system is controlled by adjustable air intakes and ducts to suit different applications. By circulating air through the house's crawl space during severe freezes and the hottest heat, the crawl space temperature can be utilized to improve the efficiency of the heat pump. The dried air flowing through the outdoor unit can be circulated to regulate the humidity of the crawl space. It is a good idea to close the ventilation bones of the crawl space as the outside air cools down, so that warm air cannot be gravitationally vented out of the crawl space.

The invention can be installed in almost all existing crawl space houses in addition to new construction. It is estimated that there are tens of thousands of small houses with risk structures in their sub-floors in Finland. The invention can quite easily prevent moisture damage caused by under-ventilation and possibly stop the worsening of damage that has already begun. The equipment is easy to inspect and maintain, as compared to equipment located in crawl space. The equipment does not consume extra energy as dryers placed in culvert enclosures with crawl space, but produces good energy for heating the house. The enhanced ventilation capability of the crawl space is virtually a free addition.

Other benefits include the sound-absorbent structure and appearance of the housing outer unit. The housing can be coated with materials similar to the facade of the house and the plinth, which may make it easier to place equipment that is restricted by some design regulations. The enclosure dampens the ambient noise and, when the structure is built on its own foundation, no sound from the outdoor unit is carried inside the house, as can happen with wall-mounted installation methods.

Compared to geothermal solutions, heat-absorbing solutions are easier to implement. In some areas, it is not possible to carry out a drillhole, and the existing smaller urban areas often do not allow for a digging circuit. The present invention can potentially improve the efficiency of the air-to-water heat pump, which draws energy from the air, throughout the year, so that it is not necessary to use a backup heat source. The efficiency of modern air-to-air heat pumps is very competitive with geothermal heat solutions with sufficiently warm supply air. The sliding roof of the housing allows all parts of the air heat pump to be serviced and there is no risk of leakage to the geothermal circuit.

With current installation methods, the outdoor unit of the air heat pump is generally mounted either on its own rack or on a wall-mounted rack. The fan of the outdoor unit usually draws air from the wall and pushes it away from the building. As the outdoor unit evaporator heats up the filing fluid in the machine, cold water condenses on the machine, which drains from the opening at the bottom of the machine. During frost, water freezes under the machine if it has not been drained or pumped immediately to somewhere warm. The ice must be mechanically removed so that it does not interfere with the operation of the machine and slides and blocks nearby routes. Depending on the efficiency, COP, the outdoor air machine loses its efficiency as a heat pump when the frost becomes high enough. In colder air, the house must be heated with alternative heating methods or with electrical resistors in the heat pump.

The benefit of the enclosure arrangement compared to the current installation depends on the technical characteristics of the enclosed heat pump and e.g. the area, volume, materials, humidity and heat leakage of the crawl space to be utilized. Each installation site is different and therefore it is not possible to specify quantitative values for how much the equipment improves the energy efficiency of the heat pump.

The following advantages are the improvements provided by the invention compared to the present installation: The invention allows the condensation water of the heat pump to remain molten, whereby the water can be discharged to an out-of-house stormwater drain or other reasonable location, such as a house drain. The invention enables geothermal heat stored in the ventilated underfloor of a house to be utilized during the freezing season and to improve the efficiency of the heat pump by several times. During the heat of the invention, the cooler air of the crawl space can be utilized to improve the cooling efficiency of the heat pump. - The invention makes it possible to ventilate and heat the structures and air of the crawl space in the spring, whereby moisture condensing therein is removed much faster than gravity. The invention can be used to dry the air of a crawl space bottom. - The invention can be used to recirculate air from a crawl space, if weighted air circulation is not sufficient, for example in chest solutions, if the ventilation hatches cannot be realized or the floor of the house is large and complex. The invention allows the removal of radon or other harmful gases in the bottom. The invention enables the heat pump outdoor unit to adapt to the appearance of the house. The housing can be coated with the same material as the plinth and walls of the house. The invention significantly reduces the sound level and energy consumption of the outdoor unit.

There are many currently known implementations of creep and soil heat: - Submerged manifolds, circulating liquid, have been built to preheat and cool the heat exchangers of the ventilation unit. - There are several commercially available thermal convectors using a liquid recirculating collection circuit to connect to the ventilation duct. - The heat pump outdoor unit is permanently installed in the crawl space. Utility Model Number U20110135 - Ventilation inlet ducts are installed to circulate in crawl space whereby the air warms up through the surface of the duct. - The ventilation duct is embedded in the ground so that it is preheated or cooled before entering the house. - In order to improve the efficiency of the air source heat pump, connection pieces have been developed to improve the efficiency. Patent application 20116186. - Geothermal has been utilized by sucking air from gravel-like porous soil into the heat pump. Patent 100800328 B1

However, none of the above solutions provide as versatile a usability as the present invention and it is generally not feasible to install them in a finished house.

DESCRIPTION OF THE DRAWINGS

In Fig. 1, the housing arrangement is shown from above without the roof structures (20). The inlet and outlet side air passages (23 and 24) are closed and the housing base (28) of air passages (25 and 26) open. Doing so would completely circulate the air through the crawl space. The air dried by the heat pump's outdoor unit (1) then circulates through the crawl space (22). If the crawl space (22) should now be an external fan, for example, a central vacuum cleaner excess pressure caused by the crawl space leading to the exhaust pipe, it is eliminated by the inlet side (4) in the upper part of the pressure relief valve (10).

In Fig. 2, the housing arrangement is depicted from below without the frost insulation of the housing and the base plate (17). The inlet and outlet side air passages (23, 24) are attached to the base and air passages (25 and 26) open, so the heat pump outdoor unit (1)-drying the air circulating through a pipe system (6,7,12 and 13) through the crawl space (22). If necessary, warm air is blown into the machine base (8) by means of a thermostatically controlled fan (27) along the pipe (9) from the creep chamber (22) and the condensation water is gravitationally discharged along the outlet pipe (15).

In Figure 3, the housing arrangement is illustrated from the front oblique or discharge side (5). Outlet structure of the air passage (24) has not been drawn so that the whole is more visible. The outlet side (5) is in a position blowing to the outside air, i.e. the airway (26) of the housing plinth (28) is closed. If the inlet side (4) is in the open air position, the heat pump will use the open air. If the input side (4) air paths (23 and 25) as shown in Figures 1 and 2, the housing arrangement sucks air crawl space (22) and the negative pressure. Then the replacement air enters through the ventilation hatches of the plinth (14) and the air in the crawl space (22) is effectively exchanged.

In Figure 4, the housing arrangement is depicted on the inlet side (4), i.e. rearward, and is in open air mode. Inlet structure of the air passage (23) has not been drawn so that the whole is more visible. If the entry side of the base air path (25) is opened and the inlet-side air path (23) is closed partly, the heat pump absorbs from the air by making use of the crawl space (22).

Figure 5 is a bottom view of the house crawl space (22) showing the principle of piping (12 and 13) to be installed in the crawl space (22) and the humidity (18) and temperature (19) sensors that may be installed in the crawl space (22). Through the closed bottom structure (17) of the housing (2), the end of the condensate drainage pipe (15) is exposed.

DETAILED DESCRIPTION OF THE INVENTION

The invention includes an air heat pump outdoor unit (1) dated foundation (17), insulated konesokkelista outdoor unit (8), insulated from the housing (2) show ilmateineen (23, 24, 25 and 26), the inlet (4) and an outlet side (5) The separating eristekaistoineen (3 ), a removable or openable roofs (20) and the upper part of the inlet side (4) of the installed pressure relief valve (10) of the house through the base (14) of the crawl space (22) of the leading ventilation channels (6 and 7), crawl space for supplying air to the tubes (12 and 13), a heat pump a condensate water collection trough (16) and an outlet (15), a crawl space humidity sensor (18), and crawl space and outdoor temperature sensors (19), and air flow regulating airway controls (21).

Innovation idea is to install air heat pump outdoor unit (1) such that the instrument front and rear side of the air flow is as free as possible and kotelojärjestelylle is very space. Most preferably, this is done by installing the outdoor unit (1) transversely of the house, with the side facing the terminals leading to the indoor unit facing the building. In this case, the air flow of the fan is not directed directly into the house structures to cool the jacket and the air can flow as freely as possible while the heat pump (1) utilizes outdoor air. The outdoor heat pump outdoor unit (1) is mounted on its stand, which is usually supplied with the outdoor unit (1). The pedestal is mounted transversely to the building on a solid insulated base (17), for example a concrete pouring of frost. The outdoor unit (1) is enclosed (2) in hermetically insulated walls, the openings of which are adjustable air paths (23 and 24) for convenient air supply from different locations to the outdoor unit (1). The tubes (6,7,12 and 13) leading to the sizes of the housing (2) into the crawl space (22) are dimensioned sufficiently large in relation to the external dimensions and air volume of the outdoor unit (1) so that the machinery of the outdoor unit (1) The frame of the housing (2) consists, for example, of lower runners, corner posts and wall posts with mounting grooves for airtight insulating panels to be inserted from above. Holes (6,7 and 9) are made in the housing (2) and in the house plinth (14) for the condensate drainage (15) and the ventilation ducts (12 and 13) of the crawl space (22) and the machine base (8). The insulating plate insulates the base of the heat pump (1), i.e. the machine socket (8), and prepares a lead-through (9) therein for supplying warm air from the crawl space (22). The thermostatically controlled fan (27) is mounted in the connecting tube (9) of the machine shuttle and the creep chamber (22). The casing plinth (28) is insulated and installed through the plinth (14) through-passage channels (6 and 7) and adjustable air paths (25 and 26) separating the upper part of the casing (2), which can shut off airflow into the crawl space (22). Isolate the front wall of the housing (2) and install the adjustable supply air and exhaust air paths (23 and 24) on the sides of the housing (2). Between the sides of the outer unit (1) and the inner walls of the housing (2), insulating strips (3) are provided separating the inlet (4) and outlet (5) so that the air flow blown by the outdoor unit (1) (5) back to the inlet side (4). The top edges of the upright posts of the housing (2) are secured to each other by a frame beam with a groove with a width of the special TV. The frame of the housing (2) is stiffened by oblique cuts if the plate is not a sufficient stiffener. The vertical columns of the housing (2) are provided with a structure corresponding to the facade of the house, for example, for paneling, plasterboard or pre-plated stone. The entire structure is covered (20) in an airtight housing (2) and secured by an insulating strip (3) to prevent air from circulating from above the outlet unit (5) to the inlet side (4). The walls of the housing (2) can also be constructed of ingots or other airtight and insulated assembly.

The inlet side (4) and the outlet side (5) of the housing (2) have adjustable air paths (23 and 24) for adjusting the amount of outdoor air used by the outdoor unit (1) from fully open to fully closed position. A housing (2), the inlet (4) and an outlet side (5) with base (28) is ducted pipes (6,7,12 and 13) through the building base (14) of the underfloor space (22), which is rossipoh-carrier. The input (4) and outlet (5) amounts of air can be adjusted to the crawl space of the building (22) of negative pressure, air, or dry overpressurises controlled manner.

Vacuuming ensures the escape of radon and any other harmful gases from the crawl space (22) and intrusion inside the house.

The stand or machine base (8) is insulated as a separate part from the rest of the base (28) of the housing (2). The machine socket (8) under the outer unit (1) has a collection tray (16) for the condensate drain, for example, a standard manhole cover. From the machine base (8), the condensate drainage pipe (15) leads either directly through the housing base structure (17), for example, to a stormwater pipe or through the house base (14) to the house drain.

The machine base (8) is blown with air through a pipe (9) from the crawl space (22), if necessary by means of a small thermostatically controlled fan (27), so that the machine base (8) is not frost-free. As the fan (27) operates, its hot air blown from its crawl space (22) is discharged through the roof of the machine base (8) to the structures of the outdoor unit (1) along the same path (11) from which condensate drains from the outdoor unit (1). This keeps the condensation water melted and drains away from the structures. A housing (2), the base (28) comprises an open air passages (25 and 26) separating the inlet (4) and the outlet side of the air space (5) of the house in the crawl space (22) leading from the air ducts (6 and 7), if necessary.

The plinths (14) of the house are provided with through-ducts (6 and 7), dimensioned according to the amount of air required by the fan of the heat pump (1), and the pipes (12 and 13) leaving them into a crawl space (22). Tubes hot side or inlet side (4) (12), if necessary, to suck the front crawl space (22) and the left edge of the air, by the "cold" and a dry side of the exhaust pipes (13) are led to the rear and right side of the crawl space (22). This allows the air in the crawl space (22) to circulate and change over as wide an area as possible. In the crawl space (22), for example, the tubes (12 and 13) function as solid tubes or flexible accordion tubes, whereby the air dried by the outdoor unit (1) during the heating season and heated during the cooling season to the crawl space (22) is blown. Apertures or valves are provided in the tubes (12 and 13) to allow air to be blown over a sufficiently wide area, taking into account the diversity of the crawl space (22). In this way, the bottom of the chest solution can also be ventilated from an area where weight vents are not reasonably practicable.

Due to the drying feature of the plant, the vents on the plinth (22) of the crawl space (22) can be closed securely in the autumn when the outdoor air begins to cool down the crawl space (22). In a new building, the crawl space (22) can be made completely closed or equipped with ventilation hatches. The ventilated design allows for a heavy charge of heat during the summer season. However, in well-insulated underfloor solutions, it is advisable to close the ventilation hatches at least during freezing temperatures. This keeps the heat in the structures.

The air passages of the tops of the sides of the housing (2) can be separately opened so that either the inlet (23) or the outlet (24) is only open, or both are open or both are completely or partially closed. The opening parts (23 and 24) may be manual or motor driven and controlled by the automatic control actuators (21) based on the values provided by the temperature (19) and humidity sensors (18). Normally, if there is no need for ventilation or drying in the crawl space, the heat pump (1) uses outdoor air as its energy source. During the heating season, below the frost limit defined by machine efficiency, the air starts to be drawn out of the house crawl space (22), and during periods of severe frost the air circulation can be completely closed from outside. Once the frost has cooled, the air circulation can again be opened to utilize the outside air, whereby the heat of the possibly cooled creep space (22) is raised by the geothermal heat stored in the soil. Similarly, during the cooling season, the air heated by the outdoor unit (1) can be recirculated to the crawl space (22) to warm the soil.

The fan speed of the outdoor unit (1) of the inverter heat pump adjusts to the temperature of the air used, whereby in severe frost the fan speed is significantly reduced by using warm air from the creep mode (22). This saves energy and reduces the sound level of the outdoor unit (1).

For the sake of the safety of the structures, it is important that there is no organic and moldy creep in the crawl space (22) of the house. If necessary, the frost insulation will only be done in the vicinity of the insulated plinth (14), so that warm energy can be stored in the ground. If necessary, gravel fillings separated by a filter cloth shall be made against the ground. The base structure may be steel, concrete, hollow core slabs or wood. The bottom must be well insulated above the load-bearing structure but the underside may not be insulated so that the structure can also act as a heat accumulator. In wood-based soles, the system ensures that the crawl space (22) dries better than gravity, but moisture monitoring is emphasized over other structural solutions. A small heat leak through the floor from the living area ensures that the wooden structure is not the coldest part of the base and thus condenses water on the wooden surfaces. The ground may have a vertical, water-sealed, vertical well that can collect excess moisture when cold. If necessary, the deck may be closed if the environmental conditions indicate that the open pit should not be in the crawl space (22). During the coldest period, however, the heat is released from the mine by evaporation of the water and by the circulation of groundwater, which can be recovered by means of the heat pump (1). The more evaporated the water, the drier the heat pump (1) has dried the air. This causes additional heat to be released during the harshest frost periods as the temperature difference tends to stabilize. The water discharged by the pump, possibly installed in the well, is replaced by water from deeper soil, which can also improve the energy in the creep space (22).

In the crawl space (22), it makes sense to supply excess heat exiting the house. For example, a central vacuum cleaner exhaust pipe that delivers hundreds of cubic meters per hour of room temperature air, even in the freezing cold. overpressure caused by excess air source leaves the crawl space (22) konesokkeliin (8) along the connecting pipe (9) and the upper part of the heat pump structure and the housing (2) in the machine base (8) at the top via the through-hole (11) the inlet side (4) safety valve (10) to the atmosphere and heated to this further increased the structure of the outdoor unit (1). Solar-heated air can also be blown into the crawl space (22) by separate equipment. If the waste water is collected in a tank and recycled, for example, to a toilet flush, it is advisable to place the water tank in a crawl space (22) so that the energy contained in the waste water will also heat the structures.

The efficiency of the equipment is determined by the insulation strength of the plinth (14) of the house, the surface area of the crawl space (22), the volume, the soil quality and moisture, and the existing structures and heat sources. The new building plinth (14) is easy to insulate throughout, and it is possible to implement a vertical pipe extending into groundwater, even as a standard drainage well. For already built houses, the arrangement can be accomplished by providing sufficient penetrations (5 and 6) in the plinths (14) and the ventilation ducts (12 and 13) into the creep space (22) by means of a flexible threaded pipe or any moisture resistant pipe. The appearance does not matter in the crawl space (22), and surface defective or dismantled pipes can be well utilized. An already installed heat pump (1) can be upgraded to utilize the heat of the crawl space (22) and ventilate the underside by moving the existing outdoor unit (1) into the housing.

In addition to the crawl space (22), the machine may be installed to utilize the heat of a storage building, a ground cellar, a loft, a mine, a mine or a former barn or other similar structure. It does not matter as long as it is close enough to the house to be heated and the property in question. the humidity of the heat source can be regulated and it is warmer than outside in severe freezing temperatures and can be supplied with air circulation piping from the housing.
