Device for distribution of water for heating

Abstract

A hydraulic device for distributing water for heating comprising a body (37) in which at least the following are defined: at least a delivery pathway (39) for water for heating and extending from an inlet (38) for the water for heating, destined to be connected to a delivery of a centralised plant (17), to an outlet (49), destined to be connected to a low-temperature heating plant (12b) and / or to a heat exchanger (3) with sanitary water; a first pathway (53) for return water from a low-temperature heating plant (12b) extending from a first inlet (52) for the return water from the low-temperature heating plant (12b) to a first outlet (54) for the return water; a second pathway (63) for the return water extending from a second inlet (62) to a second outlet (64), destined to be connected with a return in the centralised plant (17); and a mixer group (55), arranged between the delivery pathway (39) of the heating water and the first pathway (53), destined to determine a flow of return water to be pre-mixed with the water for heating in the delivery pathway (39) such as to obtain mixed water having an intermediate temperature, suitable for sending into the outlet (49) for water for heating.

Description

technical field [0001] The present invention relates to a device for selectively distributing heating water, eg for distributing heating water to or from a heat exchanger. The invention can be applied, for example, to those users known as satellite modules, i.e. in thermal-hydraulic control centers capable of autonomously managing heating and generating sanitary heat in the presence of a centralized system Water, this centralized system is often not only found in residential or commercial buildings. Background technique [0002] In any case, the invention can also be applied in different types of devices than those described above. As is known, in the user satellite module, or user satellite, in case the domestic user needs sanitary water, usually the fluid of hot water from the boiler of the centralized plant is sent to the heating plant, or to the heat exchange A heat exchanger by means of which sanitary water from the general water supply is heated to a set temperature....

AI Technical Summary

Problems solved by technology

[0014] These solutions likewise show some disadvantages, since they lead to frequent actuation of the selector valve, with the consequent increased risk of wear or misoperation of the selector valve itself, which is a critical component of the system

[0015] Furthermore, these solutions lead to energy losses, since in order not to actuate the selector valve too frequently, they tend to overheat the exchanger completely unnecessarily when the valve delivers all the heated water towards the exchanger, and tend to overheat the exchanger when Other times allow for overcooling of the exchanger

Furthermore, these systems are complex, expensive and very fragile
