Description

Title of the invention: Hydraulic connection device for heat pump

[0001] The present invention relates to a connection device made in the form of a compact module allowing the hydraulic connection of a heat pump or any other heat or cold production unit to a heating or cooling installation of a building.

[0002] Installing, for example, a heat pump on a building's heating or cooling system requires time and experience in order to fix and connect all the components necessary for the proper functioning of the heat pump.

[0003] The object of the present invention is to design a connection device consisting mainly of a compact module which allows the hydraulic circuit and connection of a heat pump or any other heat or cold production unit to be made simple and quick to a building's heating or cooling installation.

[0004] It should be noted that installation is simplified and commissioning is rapid because the compact module is factory-assembled and tested, allowing for a universal hydraulic connection. When a monobloc heat pump is combined with the compact module, the latter requires no refrigerant connection.

[0005] On the other hand, the cost of installation is reduced because the compact module includes all hydraulic components connected at the factory, facilitating and reducing installation time.

[0016] DESCRIPTION OF THE INVENTION

[0017] Figures 1 and 2 show a connection device 1 made under the form of a compact module 11 allowing the hydraulic connection of a heat pump or any other CPA heat or cold production unit to a heating or cooling installation of an ICF building.

[0018] The compact module 11 consists of a primary PA hot / cold power supply circuit allowing connection of the SU output of the external production unit CPA with the El input of the building's ICF heating or cooling system.

[0019] The compact module 11 includes a secondary return circuit SR allowing the return RI of the building's heating or cooling installation ICF to be connected with the EU inlet of the outdoor production unit CPA.

[0020] The compact module 11 consists of an inertia tank or reservoir 13 having a primary inlet 13a with which said primary supply circuit PA cooperates and a primary outlet 13b cooperating with a circulator 6 enabling the primary circuit PA to supply hot or cold to the building's heating or cooling installation ICF.

[0021] The inertia tank or tank 13 also includes a secondary inlet 13c with which the secondary return circuit of the heating or cooling system ICF cooperates and a secondary outlet 13d cooperating with a magnetic settling filter 15 allowing the connection of the return of the heating or cooling system ICF of the building with the inlet of the outdoor production unit CPA.

[0022] The inertia tank or vessel 13 is designed for exclusive use in a closed circuit with an external CPA production unit. The inertia tank 13 reduces the number of start-ups and shutdowns of the CPA production unit in the event of rapid temperature variations.

[0023] The inertia tank or balloon 13 of the compact module 11 has in its lower part a ball valve 12 allowing the draining of said tank.

[0024] The inertia tank or balloon 13 of the compact module 11 includes an immersion heater or auxiliary resistance 16 allowing, if necessary, the temperature of the water circulating in the primary circuit PA to be raised.

[0025] The compact module 11 further includes an expansion vessel 2 which is connected via a flexible hose to a chandelier 4 in the inertia tank or balloon 13.

[0026] The chandelier 4 is a safety group made of composite material comprising mainly a pressure gauge with an automatic shut-off valve, an automatic air vent and a safety valve.

[0027] The chandelier 4 may include a pressure gauge with an automatic shut-off valve.

[0028] The compact module 11 includes a support plate 17 allowing it to be wall-mounted.

[0029] The compact module 11 includes an electrical box 10 which is connected to a control device 18 which may include an outside temperature probe 3 and a remote control box 5 in order to control the heating and cooling temperature of the outdoor production unit CPA.

[0031] It is understood that the connection device 1, which has just been described and illustrated above, has been done so for the purpose of disclosure rather than limitation. Of course, various modifications, alterations, and improvements may be made, without departing from the scope of the invention.
