Definitions
- the object of this invention is a thermo-refrigerator unit for the production of hot water for heating and sanitary/domestic uses and cold water for air conditioning/cooling purposes, particularly suitable for applications in the residential and tertiary sectors.
- thermo-refrigerator units It is common knowledge that currently there are significant problems in rationalizing thermo-refrigerator units, the reason being that as of today it has not been possible to integrate the various functions in a rational mode so as to optimise the logistic of the heat transfers and of the consumptions.
- the purpose of this invention is to provide a solution to the aforementioned problems by offering a compact thermo-refrigerator unit for the production of hot water for heating and sanitary/domestic purposes as well as cold water for air conditioning/cooling systems.
- This unit groups together in a single configuration all those components necessary for the thermo-hydraulic functions, thus producing an ensemble made up of several components that interact with each other, obtaining a final product that maintains the typical technical requirements for the installation and application of the known wall-mounted or base boilers, widely used for the autonomous heating of residential and tertiary units.
- thermo-refrigerator unit wherein it is possible to maintain the typical installation and system application requirements of the abovementioned existing technology for the production of hot water for heating and sanitary/domestic purposes used extensively in the residential and tertiary sector.
- thermo-refrigerator unit in which it is possible to reduce the overall dimensions, integrating and optimising the position of the various elements making up the unit, thus obtaining a compact and rational assembly.
- a salient purpose of this invention is to propose innovative and special solutions for the path of the intake and discharge cooling air flow required for the cold water production cycle.
- a special purpose of this invention is to realize a system with high energetic efficiency through the suitable thermal recovery of the energy produced during the thermodynamic cycle.
- thermo-refrigerator unit that, for its peculiar construction characteristics, is capable of ensuring the highest guarantees in terms of reliability and safety.
- thermo-refrigerator unit for production of hot water for heating and sanitary/domestic uses and cold water for air conditioning/cooling systems is easy to make, using components and materials readily available on the market and, in addition, it is very competitive from an economic point of view.
- thermo-refrigerator unit for the production of hot water for heating and sanitary/domestic uses and cold water for air conditioning/cooling purposes illustrated with the aid of the enclosed drawings, which are supplied for information purposes only and are not meant to be limitative, where:
- thermo-refrigerator unit for the production of hot water for heating and sanitary/domestic uses and cold water for air conditioning/cooling purposes, according to the invention, includes a containment framework, globally indicated with reference number 20, inside of which is contained heat exchanger 1 (between air and refrigerant fluid), which acts as a condenser.
- Heat exchanger 1 is connected to compressor 2 and, through the positioning of pressure reducer 4, to heat exchanger 3 (between the water and the refrigerant fluid), which acts as an evaporator.
- Compressor 2 can also be connected to heat exchanger 21 between the water and the refrigerant fluid that acts as a condenser, and it is foreseen as an alternative to condenser 1 to carry out heat recovery by transferring the condensation heat, produced in the refrigerating cycle, to the water of the circuit for heating and production of hot water for sanitary/domestic purposes.
- Valves system 22 (either solenoid or three-way) allows the hydraulic management of the heat recovery function, directing the flow of the refrigerant fluid towards condenser 21 or towards condenser 1.
- Compressor 2 is also operationally connected to evaporator 3, in which the water of the cooling circuit is forced by pump 5.
- the cooling circuit can also be equipped with inertial tank 6 connected to the suction side of pump 5 and to the water return piping of the air conditioning/cooling hydraulic circuit.
- Framework 20 also contains boiler 8, complete with burner, heat exchanger between water and combustion products and, if necessary, a fan properly fitted in the combustion circuit.
- the boiler is connected to water/water heat exchanger 9 for the production of hot water for sanitary/domestic purposes; the thermo-hydraulic management of the heating or domestic/sanitary hot water functions is carried out operationally by means of the three-way valve, indicated by the number 13.
- the water flow inside the hot circuit (for heating and production of hot water for sanitary/domestic uses) is forced by pump 11.
- the combustion is regulated through the relevant electronic control unit and gas valve 12.
- Boiler 8 is connected to duct 10 for the evacuation of flue gas: the other end of this duct is connected to the exhaust terminal or to an additional external duct for the remote discharge of flue gas.
- the intake of combustive air is carried out using the described hclow inlet or outlet ducts of the cooling air flow of the unit, as a result the positioning of the relevant terminal or intake point is to be considered in relation to the configuration adopted for the abovementioned ducts.
- Condenser 21 which carries out the thermal recovery, is connected to the hot water circuit, consequently it is also used as an alternative to the boiler for heating of the water.
- thermo-refrigerator unit The two hydraulic circuits of the hot water for heating and of the cold water for conditioning/cooling functions, can be interconnected in order to obtain common hydraulic connections for hot/cold water; one for water supply to the user and one for water return to the thermo-refrigerator unit.
- specific valves 18 two flow valves or alternatively one three-way valve
- one function hereinating or cooling
- the hydraulic cooling circuit can also be separated from the heating circuit.
- valves 18 are no longer necessary and the unit is factory-equipped with two hydraulic connectors for the air conditioning/cooling user circuit and with two connectors for the heating user circuit.
- the thermo-refrigerator unit can produce both cold water and hot water at the same time, regardless of whether it is for heating or for sanitary/domestic purposes.
- thermo-refrigerator unit with the interconnected internal circuits of hot water and cold water, is equipped with expansion tank 7 common to both circuits, which in turn can be connected to inertial tank 6; in case of the version with separate hydraulic circuits for hot and cold water, in addition to expansion tank 7 relative to the cold water circuit, a second expansion tank is foreseen for the heating circuit.
- the cooling air flow on heat exchanger 1 is forced by electrical fan 14, which conveys or pulls the air so as to direct the air flow onto heat exchanger 1 and to contrast the aeraulic resistances present in the inlet and outlet ducts of the cooling air.
- thermo-refrigerator unit in order to allow the air flow pulled in by electrical fan 14 inside the same unit, through one or in general the various possibilities contemplated for the same thermo-refrigerator unit and illustrated in the aforementioned figures or in figure 2.
- air vents 23 indicated in figures 4 and 7 are provided for this purpose, and they are distributed more or less evenly along the part of the containment structure adjacent to the perimeter of the thermo-refrigerator unit that rests against the wall to which it is mounted.
- thermo-refrigerator unit not connected to external ducts, according to figures 8, 9 and 19 two grilles are provided, one for the inlet 16 and the other 17 for the discharge of cooling air; the lins of the aforesaid grilles are properly shaped for the purpose of preventing the mixing of the two air flows (inlet and outlet).
- thermo-refrigerator unit version that can be connected to external ducts
- various configurations are foreseen with external ducts 24 for the air discharge and intake grill for the cooling air or ducts for air intake too, as well as air space 19 described above that allows the flow, inside the same unit, of the air pulled in by electrical fan 14.
- the unit's connections to ducts 24 for the outlet and the inlet of cooling air flow can be positioned in the front, in the rear, on the sides, on the top or on the bottom of the unit.
- Completing the assembly electrical board 15 is foreseen for the control and the management of the thermo-refrigerator unit.
