Description

Combined system for heating household water and medium for house heating and/or for cooling of heating medium for house cooling
Field of the Invention
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.
State of the Art
The realization of heating systems that use the heat energy from the combustion boiler for heating of house residential rooms as well as for heating (sanitary) household water to be used in showers, baths etc. are well-known in the state of the art.
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.
On the output pipe of the heating medium that comes out of the boiler, there is usually a switching flowing T-valve for possible feeding with hot liquid from the secondary heat exchanger as an alternative to radiators. 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.
However in well-known systems the switching flowing T-valve is not able to differentiate the flows of hot heating medium between the radiator circuit and the secondary heat exchanger circuit. 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.
Most drawbacks of well-known solutions for heating household water and heating medium for house heating can be eliminated by using the solution according to the Czech utility model No. 31064 of the Swiss company ALMEVA AG, which is also known under the trade name (LIWA Box - GIGA). This type of the combined system for heating household water and medium for house heating eliminates the drawbacks of known configurations mentioned above that concern the regulation of heating flows in combined units for heating sanitary water, respectively household water for house rooms in the first place and indirectly fresh water as well.
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.
Summary of the Invention This invention allows drawbacks of the current systems to be eliminated thanks to the combined system for heating household water and medium for house heating and/or for cooling of heating medium for house cooling, which is - in comparison with the original combined system - supplied with an extra primary circuit of cooling medium for house cooling. The invention is the combined system for heating household water and medium for house heating and/or for cooling the heating medium for house cooling that includes at least two collaterally connected independent sources of the heating medium, e.g. boiler and/or heating pump with a common circuit for distributing and returning the heat transfer medium as well as the cooling source with a circuit for distributing and returning the cooling medium, heater and plate heat exchanger with a connected open circuit for heating and supplying the hot household water characterized in that 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. In fact 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. So the hydraulic compensator of dynamic pressures separates the connected parts, thus the common (primary) circuit and the combined system (secondary circuit) thanks to the temperature and pressure. In principle there is a insignificant pressure loss between the supply pipeline and reverse pipeline that arises when the flow speed up to 0,15 m.s-1 is reached. At the same time it removes dirt from the heating system. So thanks to the centralized medium preparation, the function of the external tank is replaced with the hydraulic compensator of dynamic pressure, in which the heat transfer medium with the required temperature is transferred. 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. In the combined system there is a floor distributor and collector for floor heating or cooling placed in the circuit for house heating system. The plate heat exchanger is on its output side connected to the open circuit for heating and supplying hot household water that includes the flow switch with sensor, circulation pump and temperature sensor, wherein on the input side the plate heat exchanger and the reverse heating branch are connected through the reverse branch via the T-valve with the hydraulic compensator of dynamic pressures.
Brief Description of Drawings
Other advantages and functions of the presented invention are obvious from the drawing where they represent:
Fig. 1 Schematic block configuration of the combined system for heating household water and medium for house heating.
Example of Invention Embodiments
The combined system for heating household water and medium for house heating and/or cooling of heating medium for house cooling (see Fig. 1) includes at least two collaterally connected independent sources of the heat transfer (heating) medium, in this case the boiler K and heat pump P with the common circuit B for supplying and reversing the heat transfer medium as well as the source F of cooling with cooling branch IF and reverse branch 2F with the cooling circuit C for supplying and reversing the cooling medium, the circuit D for house heating and the plate heat exchanger 8 with the connected open circuit W for heating and supplying hot household water. The collateral circuits Bj 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 hot output 11 of the hot heat transfer medium from the hydraulic compensator H of dynamic pressures equipped with the circulation pump 6 and the temperature sensor SI for the distributed water is divided into the exchanger branch 12 leading into the plate heat exchanger 8 and into the linking branch 13 that is connected with the mixing T-valve 7 for alternative connection of the common circuit B for supplying and reversing the heat transfer medium and/or the cooling circuit C for supplying and reversing the cooling medium with the circuit D for house heating. On its output side the plate heat exchanger 8 is connected with the open circuit W for heating and supplying hot household water that includes the sensor 9, circulation pump 10 and temperature sensor S3, wherein on its output side the plate heat exchanger 8 and the reverse heating branch 15 are connected through the reverse branch 14 from the circuit D for household heating via the T-valve 2 with the hydraulic compensator H of dynamic pressures.
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 open circuit W for heating household water contains the flow sensor 9 used to activate the preferential flow of heating medium from the common circuit B through the hot boiler branch IK and the hot branch IP from the heat pump via the mixing valve 5, hot branch 1, through the hydraulic compensator H of dynamic pressures into the plate heat exchanger 8 when there is any kind of request for household water consumption.
The circuit D of the house heating/cooling is a part of the combined system A in the form of the floor distributor and collector. The mixing T-valve 7 can be used for switching the combined system A into the cooling mode with the circuit C used for cooling. However the function of the open circuit W for heating household water will not be affected.
During various phases the function of the combined system A is as follows, wherein for experts in the field the brief description should be sufficiently comprehensible. Mode of household water preparation (FriWa)
The preheated heating medium is leaded through the mixing valve 5 with electronically controlled and ultrafast responding setting drive in direction to the heat exchanger 8 (with the circulation pump 6 in the open circuit W used for household water heating) from the hydraulic compensator H of dynamic pressures, wherein the temperature of heating medium is maintained below 50 °C to prevent stainless steel plates in this heat exchanger 8 from becoming calcified, where the calcium loss occurs at the temperature 55° C or lower.
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. Simultaneously the temperature of the household water in the circuit W is prevented from varying. The described household water heating comes up when the sensor 9 or other sensor with a built-in flow switch registers a request for household water consumption.
The external part of the open circuit W for household water behind the desk plate exchanger 8 is eventually equipped with the reversal loop Z that has the circulation pump 10 and measuring sensor S3 for temperatures not exceeding 55 °C, wherein in this part of the open circuit W the hydraulic bond needs a minimum amount of household water, which effectively prevents Legionella from breeding in household water, wherein the relevant supplies in the system are prepared in advance for the reversal loop Z installation. The circulation pump 10 for the household water can be delivered on request. When used, the hydraulic bond arises as described in the Fig. 1. The relevant supplies are prepared for a supplemental installation.
The measuring sensor S3 measures the circulating temperature of the reversing water in this reversal loop and disables the circulation pump 10 for household water in this loop, when the heated household water in the main circuit W starts flowing again as described above to save the energy.
Mode of mixing heating medium for house heating system
To allow the required temperature of the heating medium supply for radiator s/floor heating etc. to be reached as calculated according to the outdoor temperature (or indoor temperature), the same electronically controlled mixing circuit is used as when preparing household water.
The direction of the heating medium flow is switched using the T- valve 7, wherein for measuring and regulating the temperature of the inflowing heating medium the sensor SI is used.
The heating medium is collected through the circuit B, wherein its branches inside - the hot boiler branch IK from the boiler K and the hot branch IP from the heating pump P are connected with the hydraulic compensator H of dynamic pressures. In fact the hydraulic compensator H of dynamic pressures is a small tank through which the heating medium flows and in which the supplying 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.
The flow volume in the circulation pump 6 can be set up with speed regulation to prevent noise emissions in this mixing circuit system, respectively in the circuit D for house heating, and to save electric energy.
Heat production mode
The regulated request for the desired amount of heat by external heat source, as from the boiler K, e.g. burning oil, gas, or as heating pump P, is realized by a non-displayed regulator, e.g. spatial thermostat.
Other automatic heat sources that can produce discontinuous energy may be connected to an external tank that is not a part of the combined system A.
Floor cooling mode
The circuit D for house heating is a part of the combined system A that consists of the floor distributor and collector. The mixing T- valve 7 can be used to switch the combined system A into the cooling mode with the circuit C. However the function of the open circuit W for heating household water will not be affected. The combined system A contains an independent source F of cooling and with help of the cooling circuit C integrated collaterally into the combined system A the mixing T-valve 7 can be used to put the cooling medium into the floor distributor and collector for floor cooling, mainly during the summer period. The regulated request for the desired amount of cool is realized by a non-displayed regulator, e.g. spatial thermostat.
Technical Applicability
The combined system for heating household water and medium for house heating and/or for cooling of heating medium for house cooling is designed for economical and ecological heating and/or cooling of interiors in numerous, especially housing units located in one object.
