Summary of Invention
  • the proposed technical solution envisages employing a heat pump or another autonomous heat generator in a centralized heat and hot water supply system. Adjoining a heat pump or another autonomous heat generator equipment to the centralized heat supply system scheme of the building ensures a general increase in heat energy production due to alternate transfer of heat to the building from the operating centralized heat supply system or a heat pump and (or) another autonomous heat generator.
  • the novelty of a centralized hot water and heat supply system comprising the main circuit heat supply network, a set of pipes and equipment of a heat node, as well as the indoor hot water and heat supply system, consists in that a heat pump and (or) another autonomous heat generator comprises an independent module being connected to the main circuit pipeline supplying heat to the building and through a heat exchanger to hot water supply system of the building.
  • an independent module may comprise a heat pump and an electrode boiler - jointly or apart from each other.
  • control unit designed to evaluate at preset time intervals the heat pump or electrode boiler coefficient of heating performance (COP) based on the system data available at the evaluation moment, to compare the defined COP value with the predetermined one and depending on the result to connect or disconnect the module and also to process other parameters impacting maximal efficiency of the system operation.
  • COP heat pump or electrode boiler coefficient of heating performance
  • the essence of the invention consists in combined use of two heat energy sources in systems supplying heat and hot water to buildings:
  • heat energy generated during autonomous operation of a heat generator or heat pump by way of accumulation and conversion of energy from a natural heat source (renewable heating medium) or from an utilizable (technogenic) source by means of installation inside the building of equipment required for a combined use;
  • temperature gages installed on pipeworks of an autonomous heat generator of any type (all having a common feature to transform the primary source energy into heat energy at a COP (coefficient of performance) of at least, 1.5, e.g., a heat pump, a flow-type electrode boiler);
  • control unit evaluates COP. Having compared the resulting value with the predetermined one (COP can be preselected individually with regard to current heat and electricity prices) the control unit sets up either disconnection and transfer to an alternate heat source or further operation of a heat pump or another autonomous heat generator.
  • COP can be preselected individually with regard to current heat and electricity prices
  • the control unit sets up either disconnection and transfer to an alternate heat source or further operation of a heat pump or another autonomous heat generator.
  • its connection moment may be set up by the control unit after a preset period of time or depending on the data on ambient conditions change (e.g., the temperature has raised above the predetermined value).
  • Such an operation algorithm can be updated depending on the heating system operation conditions and it allows employing a heat pump or another autonomous heat generator only during such time intervals when its operation is most effective. During other time intervals alternate heat sources are employed, which ensures a considerable economic effect by diminishing the building and room heating costs.
  • the proposed solution offers an opportunity to choose the mode of supplying heat from heating medium to the building by an individual programme, controlling preselected indoor temperature by an individual programme and automatically regulating the necessity to connect or disconnect a heat pump or another autonomous heat generator depending on the outdoor temperature. Without a considerable decrease of COP currently existing heat pump designs are not effective at outdoor temperature below - 8 °C. Consequently, given factors should be taken into account while programming timely disconnection of a heat pump. Fulfilment of individual programme tasks is regulated with regard to preselected indoor temperature parameters and factual outdoor temperature. Another important factor for air heat pumps is humidity of the air from which the heat pump draws heat. High air humidity (higher than normal) decreases COP of an air heat pump at an outdoor temperature below 0 °C.
