Definitions

  • the present disclosure relates to a control device for heating, ventilation, air-conditioning installations. More particularly, the present disclosure focuses on a control device for an installation with no thermal buffer. The instant disclosure also relates to heating, ventilation, air-conditioning installations with such a control device.
  • HVAC heating, ventilation and / or air-conditioning
  • a heat pump is commonly employed as a heat source in conjunction with a thermal buffer.
  • the thermal buffer of a HVAC installation functions to ensure sufficient flow (of water) through a heat source. If the flow of the medium through the heat source drops below a minimum level, the heat source will experience frequent stop / start cycles. Those frequent stops and / or starts generally lower the overall efficiency of the HVAC installation. They may also result in (mechanical) failure of the heat source.
  • thermal buffer is normally added to HVAC installations to ensure continuous operation of the heat source.
  • a thermal buffer does, however, increase
  • the present disclosure improves on control devices for HVAC installations.
  • the instant disclosure aims at providing a control device that allows for HVAC installations without thermal buffers.
  • the present disclosure provides a control device which allows HVAC installations to operate without thermal buffers while avoiding disconnections of heat sources.
  • a control device as per this disclosure is typically part of a heating, ventilation, air-conditioning installation.
  • a control device in accordance with the instant disclosure may, in particular, be part of a system for central heating.
  • control device as per this disclosure will avoid interruptions in the operation of a heat source by changing a setting of a load circuit of a HVAC installation.
  • the control device may as well avoid disconnection of a heat source by changing a temperature setting of a HVAC installation.
  • the control device as per the present disclosure influences (the load side of) a HVAC installation so as to not interrupt the operation of a heat source.
  • the instant disclosure thus provides a method for control of a HVAC installation with a heat source, with a heat exchanger and with at least one load circuit in communication with the heat source through the heat exchanger, the method comprising the steps of determining a minimum amount of heat to be generated by the heat source required for continuous operation of the heat source , determining a minimum flow of a medium through the at least one load circuit, wherein said minimum flow suffices such that the heat source can generate its minimum amount of heat and such that the heat exchanger can transfer said minimum amount of heat from the heat source to the at least one load circuit, determining a critical flow of a medium through the at least one load circuit, wherein the critical flow is larger than the minimum flow of a medium through the at least one load circuit, measuring an actual flow of a medium through the at least one load circuit, determining whether said actual flow of a medium is less than the critical flow of a medium through the at least one load circuit, determining an extra flow of a medium through the at least one load circuit to be added to said actual flow of a medium through

  • the present disclosure further provides a control device for synchronous heat and / or cooling of the separate parts (rooms) of a commercial, residential or industrial building.
  • the effect of synchronous heating and / or cooling is achieved by allowing all of the parts (all of the rooms) of a building to increase or decrease temperature in parallel. Due to synchronous heating and / or cooling a demand for heat will, in general, be large enough so as to avoid unnecessary starts and / or stops of a heat source.
  • the present disclosure further provides a heating and / or ventilation, and / or air-conditioning installation with a control device according to the instant disclosure.
  • the present disclosure further provides a building with a heating and / or ventilation, and / or air-conditioning installation with a control device according to the instant disclosure.
  • the control device of the present disclosure is typically part of a heating, ventilation and / or air-conditioning (HVAC) installation.
  • HVAC installation as shown on Fig 1 comprises a closed loop heat source such as a heat pump.
  • a suitable medium especially a refrigerant, is circulated through the closed loop circuit 1.
  • the medium may, by way of non-limiting example, be a R-401A, R-404A, R-406A, R-407A, R-407C, R-408A, R-409A, R-410A, R-438A, R-500, or R-502 blend.

  • a HVAC installation as per Fig 1 also comprises one or several load circuits 3.
  • These load circuits 3 may, by way of non-limiting example, be underfloor heating installations, central heating installations, (central) air-conditioning installations or combinations thereof. It is envisaged that the load circuits 3 and the closed loop circuit communicate through a heat exchanger 4.

  • Heat sources 1, 2, 5 in operation typically require the generation and delivery of a minimum amount of heat. This minimum amount of heat is then transferred via a heat exchanger 4 to a load circuit 3. The load circuit 3 finally absorbs the minimum amount of heat generated by the heat source 1, 2, 5.

  • the extra flow preferably exceeds a given threshold when the extra flow exceeds a start threshold.
  • the control device may be configured to dynamically alter the start threshold and / or the stop threshold of the heat source 1, 2, 5. The control device may, for instance, dynamically alter these thresholds in accordance with the magnitudes of the flow(s) through the load circuit(s) 3.
