Definitions

  • the invention concerns the combined system for heating household water and medium for house heating and/or for cooling of heating medium for house cooling that includes two independent sources of heating medium, as a boiler unit (stationary boiler) and/or heating pump etc. and/or cooling source, using primary circuits connected collaterally into the combined system via heat exchanger (especially plate heat exchanger) and least one heat from the heating medium collecting collaterally connected circuit not only for the house heating system or house cooling system, but also to heat household water with an interface with help of a separate heat exchanger.
  • heat exchanger especially plate heat exchanger
  • That heating systems contain a primary heat exchanger placed opposite the boiler, through which runs the heat transfer fluid (usually water) that runs via radiators in the heated rooms as result of the pressure in the relevant circulation pump.
  • the heat transfer fluid usually water
  • This secondary heat exchanger allows the household water to be heated and distributed into the sanitary facility of the house by taking the heat directly from the heating medium of the heating system, which takes advantage of the heat energy in the boiler.
  • the mentioned valve has a binary regulation, wherein it can have only two end positions, thus one for radiator supplying (if the heated household water is not required by users at the same time) and one for supplying the secondary heat exchanger (if household water is required).
  • the command for switching the valve is given by useful control devices, when the minimal flow sensor attached to the sanitary water pipe recognizes a request for heated household or sanitary water, e.g. P,5 1/m.
  • This type of heating system allows the boiler heat energy to be used for two purposes (for heating housing rooms and for heating household water as well), but on the other hand it causes significant energy losses quite often. If there appears any kind of request for household water, heating of radiators in the house is usually stopped, so the whole and abnormally available heat energy is used to heat just a small amount of water.
  • the general purpose of this technical solution is to improve current inventions known under the name LIWA Box - GIGA by creating a new combined system with new connection layout.
  • the heating and cooling medium is prepared centrally and it is transferred into the technical room, e.g. in the building basement. Thanks to the centralized preparation, the new combined system can be placed into individual apartments no matter how many combined systems are needed, which simplifies the installation and placement; in addition the best possible technology and control system maximizes potential energy savings.

  • the collateral circuits of the combined system equipped with three valves and the plate heat exchanger are interconnected and/or separated using the hydraulic compensator of dynamic pressures.
  • the hydraulic compensator of dynamic pressures is a small tank through which the heating medium flows and in which the inflowing and reversing heat transfer medium can be mixed. Inside the combined system it takes advantage of physical laws, so on the basis of the heating medium temperature the compensator separates and compensates flows throughout the system. It is able to divide the connected hydraulic circuits to make them independent.
  • the heat transfer medium, the hot boiler branch from the boiler and the hot branch from the heating pump of the common circuit are connected with the hydraulic compensator of dynamic pressures via a remote controlled T-valve, while the cold branch from the boiler and the cold branch from the heating pump are connected with the hydraulic compensator of dynamic pressures via a remote controlled two-way valve.
  • the heating medium is centrally adjusted to the required temperature before entering the combined system and it is regulated via mixing T-valves for differential switching either to the circuit for heating household water not exceeding the temperature 55 °C, or to the circuit for house heating with possible temperature above 55 °C.
  • the hot output of the hot heat transfer medium from the hydraulic compensator of dynamic pressures equipped with a circulation pump and temperature sensor is divided into the exchange branch leading into the plate heat exchanger and a linking branch connected with the T-valve for alternative connection with the common circuit for supplying and reversing the heat transfer medium and/or the circuit for supplying and reversing the cooling medium with heating and/or cooling bodies.
  • a floor distributor and collector for floor heating or cooling placed in the circuit for house heating system.

  • the collateral circuits B j C of the combined system A equipped with valves 4, 5, 7 and the plate heat exchanger 8 are interconnected and/or separated via the hydraulic compensator H of dynamic pressures.
  • the hot boiler branch IK from the boiler K and the hot branch IP from the heating pump P for the common hot branch 1 of the circuit B are connected with the hydraulic compensator H of dynamic pressures via remotely controlled mixing T-valve 5, whereas the cold boiler branch 3K from the boiler K and the cold branch 3P of the heating pump P for the common circuit B are connected with the hydraulic compensator H of dynamic pressures via remotely controlled two-way valve 4.

  • the function of the combined system for heating household water and medium for house heating and/or for cooling of heating medium for house cooling of housing rooms is as follows:
  • the required temperature of heating medium is prepared centrally before entering the combined system A and it is controlled using mixing T- valves 2 for differential switching either to the open circuit W for heating household water not exceeding the temperature 55 °C, or to the circuit D for house heating with possible temperature above 55 °C.

  • the household water temperature is measured with the fast responding sensor 9; with help of the electronically controlled mixing regulation, e.g. by taking advantage of the mixing T-valve 7, behind the plate heat exchanger 8 the required output temperature is being set.
