Embodiment Construction

[0018] figure 1 Shown is a safety heat exchanger of a device for combining a heat pump with a drinking water supply, represented in a first exemplary embodiment by a waterworks 1 . exist figure 2 In the second exemplary embodiment shown, the device of the potable water supply installation is illustrated as a potable water container 2 . The invention should not be considered limited to this type of installation. Installations and installations of potable water supply facilities may include, for example, plant components for the extraction of potable water, pumping stations, booster stations or potable water supply networks.

[0019] figure 1 The device of the drinking water supply facility in is a waterworks 1, in which the geothermal energy contained in the drinking water is transferred to a temperature level higher than the drinking water temperature by a safety heat exchanger combined with a heat pump, mainly for the consumption of the facility and saving energy .

Abstract

The invention relates to a safety heat exchanger for combining a heat pump with a device of a drinking water supply facility, said heat exchanger having a primary circuit (4) containing drinking water, a secondary safety circuit (6) containing a substance not hazardous to people's health as an antifreeze, and a tertiary circuit (7) containing a coolant. The safety heat exchanger is intended to prevent an impairment of the drinking water in the public drinking water supply. The safety heat exchanger comprises a primary circuit (4) having a feed pipe (3) connected to the drinking water supply facility and a discharge pipe (5) having electrically controllable solenoid valves (16). The primary circuit (4), or the coolant circuit (7), has a higher pressure than the safety circuit (6). The safety circuit (6) is provided with a pressure control device, which in terms of a control system is connected to the solenoid valves (16) such that the feed pipe (3) and the discharge pipe (5) of the drinking water to the drinking water facility are closed in the event of a pressure loss in the primary circuit (4) or in the coolant circuit (7).

Description

technical field [0001] The invention relates to a safety heat exchanger for installations combining a heat pump with a drinking water supply, with a primary circulation circuit for drinking water, a secondary safety circulation circuit with anti-freeze material that does not pose a health risk, and a coolant circuit Tertiary circulation loop. Background technique [0002] DE 102004061441 B4 discloses a heat exchanger for drinking water protection areas. For safety reasons, a third intermediate circulation circuit is proposed in order to be able to operate the main circulation with drinking water, aimed at protecting drinking water in drinking water sanctuaries. [0003] DE 2834442 A1 also discloses the combination of drinking water supply facilities and heat exchangers for obtaining heat. In order to obtain internal heat based on a heat pump system, part of the water is discharged from the pipe network of the central water supply facility, and the heat is obtained from the ...
