Definitions

• the water is made to circulate within a. distribution circuit towards one or more heat exchangers of the water-air type, including for example radiators, radiating panels or convective ventilation systems.
• Figure 4 is a plan view of the distribution module placed within a containment box.
• the first refrigeration outlet 9d is shared with a first dehumidifier inlet
• This check valve is connected to the second high-temperature inlet 13b and allows the flow to move in the direction of the monoblock unit 2.
• This third manifold comprises a thermometer 18d and a temperature probe 18e which interacts with the first three-way valve 4a.
• a containment box 21 can accommodate the distribution module 1, insulation being provided inside it which can be constituted by two or more suitably contoured shells which can be arranged so as to wrap around the various components enclosed in the containment box 21.
• Such box has small dimensions, on account of the dimensions of the monoblock unit, and thus allows for an optimal insulation in a small space, as those that can be available in the housing units.
• Two configurations can be distinguished in operation, i.e. a winter configuration, which is shown schematically in Figure 1, and a summer configuration, which is shown schematically in Figure 2, and are determined by the simultaneous rotation of the handles of the second and third three- way valves 4b and 4c that conveniently modify the paths of the water flow.
• the water flow thus arrives at the fork between the duct that accommodates the adjustment valve 20 and the duct that leads to the second high-temperature outlet 13 a; the flow is divided between the two ducts as a function of the opening of the adjustment valve 20: the more it is open, the more water can flow through the duct that accommodates the adjustment valve 20.
• the third three-way valve 4c prevents, in the current configuration, the flow of hot water from reaching the refrigeration system 10 or the dehumidifier 12, that at the same time are mutually connected so that the dehumidifier 12 can operate with the refrigerated water generated by the refrigeration system 10.
• the flow of water refrigerated by the refrigeration system 10 enters the monoblock unit 2 through the first refrigeration inlet 9a of the third three-way valve 4c and a part of the water flow feeds the dehumidifier 12 through the dehumidifier inlet duct 11c.
• the water flow entering the monoblock unit 2 cannot enter the duct that is relative to the second high-temperature inlet 13b for the presence of the first check valve 15i and cannot enter the duct that is relative to the second high-temperature outlet 13a for the presence of head losses of the low-temperature system 17.
• the entire volume of refrigerated water will therefore go to the deaerator 6 and subsequently the first three-way valve 4b will manage the temperature of the low-temperature circuit 17 in the same way as the winter configuration.
• the path of the refrigerated water reaches the first three-way valve 4a without passing the adjustment valve 20 and therefore is without head losses.
• the water flow leaving the first three-way valve 4a and returning from the dehumidifier 12 through the dehumidifier delivery duct l ib returns to the refrigeration system through the second three-way valve 4b and through the refrigeration return duct 9c.
• a distribution module being provided which is particularly adapted to being used for the distribution of heating or cooling water, such module being constituted by a monoblock unit that is without water leakage and with low head losses, and being coupled with the other components of the system.
