Abstract

The system is composed of a plate-type heat exchanger and of a NTC probe controlling the sanitary hot water temperature, "integrated" inside a properly insulated storage system.
Whenever the water temperature decreases, the system acts to maintain the set water temperature; when water is delivered, the heat exchanger acts to provide for the immediate thermal exchange and, consequently, for the required thermal power values.
As a consequence, the heat losses of the plate-type heat exchanger are optimized, in order to bring the sanitary hot water at the rated temperature and to maintain it; the system presents also construction advantages, making of it a compact and integral system, requiring no connecting pipes.

Description

    1. System description
  • The system consists of a plate-type heat exchanger, having a capacity adequate to the boiler's thermal power, "integrated" within a properly insulated, stainless steel, 4.5 Its storage system (see sketch of Figure 1).
    The sanitary hot water outlet of the plate-type heat exchanger (where the probe controlling temperature is located) coincides with the water inlet of the storage system.
    On the contrary, the storage system outlet (see figure 2) is connected to the boiler's sanitary hot water outlet.
    The NTC temperature probe is designed to check the delivery temperature of sanitary hot water, and, at the same time, to maintain the storage temperature.
  • To maintain the storage water temperature, the heat, dispersed by the plate-type heat exchanger and otherwise going lost, is recovered.
    • 2. Storage system operation
  • When the NTC probe, located within the sanitary water storage system, is not satisfied, boiler's burner goes on and sanitary water is brought to its rated temperature, through the thermal exchange of the outside surfaces of the plate-type sanitary heat exchanger.
    • a) Storage maintenance system
  • Whenever the water temperature decreases, as a consequence of the thermal losses of the storage system, the system acts as when temperature is brought to its rated value, thus keeping the water temperature at its set value.
    • b) Production of sanitary water with delivery at the various thermal powers
  • When the sanitary water is delivered from the storage system, the plate-type .heat exchanger provides immediately the thermal exchange at the required thermal power values. The NTC probe in the storage system, specifically located at the outlet of the plate-type heat exchanger, keeps the delivery temperature steady.
    • 3. Advantages of the system
  • The system exploits the dispersion of the plate-type heat exchanger, which would otherwise be lost, to bring the sanitary water inside the storage system to the rated temperature and to maintain it. Moreover, one NTC probe only sets and maintains the temperature to its rated value, and adjust it during the delivery of sanitary hot water.
  • The system performance advantages are linked to the increased delivery speed of sanitary water and to the improved stability of temperature during delivery.
  • The system presents also construction advantages, since it eliminates the need of any additional storage tank, adjacent to the plate-type heat exchanger . The result is a compact and integral system requiring no connecting pipes.

Claims (7)

  1. The NTC probe brings the sanitary water to its rated temperature and keeps the delivery temperature steadily adjusted
  2. Whenever the water temperature decreases, the system is able to keep it set according to the system requirements
  3. The use of the plate-type heat exchanger provides for the immediate thermal exchange
  4. Heat losses typical of the plate-type heat exchanger are optimized
  5. Delivery of sanitary water is thus quicker
  6. Temperature during delivery is more stable
  7. Moreover this system presents construction advantages, since it eliminates the need for any additional storage tank and connecting pipe.
