Description

HYBRID SYSTEM WITH COLLECTIVE HEAT PUMP AND BOILERS GAS INDIVIDUALS

SECTOR OF THE TECHNIQUE

The present invention belongs to the sector of building installations and more specifically to the sector of thermal installations in buildings.

The main object of the present invention is a hybrid installation system with collective aerothermal heat pump and individual gas boilers, intended for collective buildings with individualized consumption, whether new buildings or rehabilitated buildings. The invention provides a domestic hot water heating system, heating or both, as well as a room cooling system, alternative to current systems, using energy efficiency technology such as a collective air-water heat pump, complemented by individual boilers in each room with individual consumption. When the system is used for the preparation of domestic hot water, the installation allows replacing the field of solar collectors prescribed in the regulations when the coefficient of seasonal performance of the heat pump reaches the value for the aerothermal energy to be considered as renewable energy. When the system is used to heat premises, the installation has a renewable energy device such as the heat pump.

BACKGROUND OF THE INVENTION

The hybrid installations of heat pump and gas boiler have been used in rehabilitated buildings of single-family housing basically, although there are realizations in collective buildings, but always with the collective heat pump and boiler. More recently, hybrid installations are also advocated in new buildings, also in single-family homes or in collective buildings, but always with collective boilers and heat pumps.

Saunier Duval Hybridization between heat pumps and boilers is a technology that began to take off for rehabilitation of facilities in single-family housing and later has been transferred to new buildings also of single-family housing. Applications of the hybridization of systems in collective housing buildings are executed with collective heat pump and also a collective boiler or, as some heat pump manufacturer points out, both individual boilers and heat pumps could be executed in each dwelling by locating the pump of heat on the clothesline. The state of the art does not contemplate hybridization with collective heat pump and individual gas boilers in buildings with individualized consumptions as described in the present invention.

EXPLANATION OF THE INVENTION

The present invention is a hybrid system with collective heat pump and individual gas boilers in each room with individualized consumption, intended for new or rehabilitated collective buildings, such as collective housing buildings, offices, etc.

The installation consists of a heat pump preferably located on the roof of the building, air-water type (aerothermal); The heat pump can be driven by an electric compression cycle or by a natural gas compression cycle or by absorption cycle. From the heat pump, a primary circuit of water is heated by the heat pump, round trip circuit to the machine, which runs through the building, in general by common area of the same; the primary circuit concludes in the connections of sanitary hot water and heating of each premises, the sanitary hot water being served from a heat exchanger preferably located in the common area of the building on the same level as the premises served; individual gas boilers (in general natural gas) that are instantaneous or with micro-accumulation are located within each room. The boilers are watertight, being able to be in addition to condensation and allow to receive preheated water from the primary hot water circuit that starts from the heat pump. Each room has sanitary hot water, heating or both, as well as cooling if necessary, individually, but with hybrid energy support from the collective heat pump. Prior to the heating or cooling connection of each premises and prior to the domestic hot water exchanger, an energy meter that serves the respective premises is located, and which accounts for the energy consumption that each premises makes from the primary ring served by the collective heat pump.

In one of the preferred embodiments of the installation, the heat pump for operation is served on the side of the outside air evaporator (aerothermal), although another preferred embodiment of the invention provides that, in admixture or not with the outside air , the heat pump uses the extraction air of the building garage if it exists, or the extraction air of the premises when there is a controlled mechanical ventilation of simple flow.

When the system is designed to serve the domestic hot water of the premises, at present, the heat pump must be sized at least to cover the minimum solar fraction prescribed in the mandatory regulations (for example Technical Code HE 4); likewise, when the value of the Seasonal Performance Factor reaches the minimum value prescribed in the regulations (the minimum value of the Seasonal Performance Factor is 2.5, for example in the Recognized Document "Average seasonal performance of heat pumps for heat production in buildings ", 2014,) the field of solar collectors for domestic hot water imposed by current regulations can be suppressed. However, the heat pump can be sized with a power that allows to cover, in addition to the minimum solar fraction for domestic hot water, a part or all of the heating needs of the premises, an aspect that will depend on the different climatic zones in those that are the buildings in which the present invention is projected, as well as of the prescriptions imposed by the designer in this regard. In addition, if the building requires cooling, the heat pump will be reversible. Therefore, the size of the collective heat pump will range from the minimum to cover the minimum solar fraction of domestic hot water to the maximum that covers all the heating and ACS thermal demands of the building and,

in summer, taking into account the demand for refrigeration of the premises.

As for the individual boilers in each room, they are sized in the conventional manner, that is, they must be provided to meet the demand for domestic hot water or heating of the premises or be provided for both services. This allows, in the event of a breakdown or in case of maintenance of the heat pump, that the premises fully maintain the domestic hot water and heating and cooling service.

The described installation can be completed with a water tank intended for hydraulic balancing of the primary ring of water supplied from the heat pump; however, in buildings with a high number of premises in which the water content of the primary ring is important, the hydraulic balancing tank could be dispensed with. The heat pump manufacturer must specify the minimum water content that the installation must have. This minimum content ensures sufficient inertia and the maintenance of a minimum operating time of the compressor, avoiding short cycles; the inclusion of this minimum water content (either by means of a balancing tank, or by the water content of the primary ring) is usually necessary even in heat pumps with a frequency converter. The deposit will preferably be located on the roof of the building and in any case with adequate thermal insulation.

The described installation is completed, like any other thermal installation, with the valves and accessories necessary for its proper operation (for example, expansion vessels, water circulation pumps, shut-off valves and circuit balancing, chimneys on deck for boilers, thermal insulation of equipment and pipes, regulation system, etc.).

The main advantages of the present invention are summarized as follows:

•

The collective heat pump can be operated electrically or by gas compression circuit or by absorption cycle; if operated by natural gas, an improvement in the machine's performance coefficient and, therefore, an improvement in the Seasonal Performance Factor is expected.

•

the installation system object of the present invention, can give in the buildings with individualized consumption, the service of sanitary hot water,

heating and cooling; The option of hosting one or more of the services indicated depends on the demands of the building.

•

If the system is designed for the domestic hot water service, the field of solar collectors can be suppressed by replacing it with the collective heat pump provided in the installation. Solar panels in certain climatic zones do not function properly; If the minimum value of Seasonal Performance Factor (currently 2.5) prescribed in the regulations is reached, solar panels can be replaced in all climatic zones by the collective heat pump.

•

As the heat pump works on outside air, the installation can work day and night, unlike solar panels where night operation does not exist.

•

If the operation of the heat pump is prioritized in front of the individual boilers, the installation is collective and the support is individual in each dwelling by means of the gas boilers.

•

The heat pump can operate both in alternative bivalent mode (alternative to boilers from certain outside air temperature values), and in series bivalent (both equipment, boilers and heat pump work, preheating the boiler water )

•

The heat pump can be high temperature (double compression for example) so that the boilers only support if necessary

•

for example, the alternative bivalent operation of the installation can be provided, so that, when the outside temperature drops below a preset value - about 7 ° C - only the boilers work, which can mean an improvement in the Performance Coefficient (COP) and of the Seasonal Performance factor (SPF).

•

The heat pump can also be low temperature, in which case the boilers must work providing sufficient energy to the domestic hot water service or to the premises heating service, so that the water temperature reaches the appropriate value.

•

no refrigerant pipes inside the building

•

preferred location of the collective heat pump on deck where adequate treatment and sound insulation can be performed.

•

This hybrid installation system with collective heat pump, can work in any climatic zone of Spain, even in the most rigorous,

l.

providing, for example, the alternative bivalent operation, depending on the disconnection temperature of the heat pump of each climatic zone.

•

If the heat pump is reversible, the heat pump can supply the refrigeration service of the premises, prioritizing the operation of the boilers for the domestic hot water service if it is provided.

•

The installation is used for new buildings, as well as for rehabilitated buildings, in which there are two or more premises (collective buildings).

•

In case of maintenance or breakdown of the heat pump (or of the boilers) the installation can continue to provide the service of domestic hot water or heating to the premises.
