Definitions

  • the present invention relates to a heat pump for heating or cooling dwelling houses and other confined spaces in which such requirements prevail, and also for heating tap water.
  • the heat pump includes a compressor, a first heat-exchanger connected thermally to a heat source, a second heat-exchanger connected thermally to a fan system, a third heat-exchanger connected thermally to a tap water system, an expansion valve, and a two-position flow-reversing switch.
  • the switch When the switch is set to a first of its two positions, the heating position, refrigerant flowing from the compressor will pass through the heat- exchanger, the second heat-exchanger, the expansion valve, the first heat-exchanger and from there back to the compressor.
  • the switch is in the second of its two positions, the cold position, refrigerant flowing from the compressor will pass through the third heat- exchanger, the first heat-exchanger, the expansion valve, the second heat-exchanger and back to the com ⁇ pressor.
  • Such heat-pump systems are used in air conditioning or climatic systems for heating living spaces or corresponding spaces in winter and cooling said spaces in summer, and are also used to heat tap water the whole year round.
  • These known systems present difficulties when wishing to heat confined spaces in winter while providing hot tap water at the same time.
  • Normally, such systems are designed either to produce heat for room-heating purposes or heat for producing hot tap water. Since it can be presumed that the structural elements from which the building concerned is built will normally have stored therein sufficient heat to allow the space-heating facility of the system to be inactive over a not too long period, without experiencing discom ⁇ fort, the tap-water heating facility of the system is normally given priority.
  • the object of the present invention is to provide a heat pump by means of which the heat available can be distri- ubbed between the confined spaces of a building and the hot tap-water system and be used to heat said spaces and said tap water in parallel, with the aid of simple means and with the least possible heat losses.
  • the illustrated exemplifying heat pump includes a first heat-exchanger or evaporator 7, one side of which is connected to an evaporator coil 13 which is intended to be placed, for instance, in a hole in the ground, for the purpose of utilizing ground heat, and in which an aqueous solution of lowered freezing point can be cir ⁇ culated with the aid of a circulation pump 12.
  • the other side of the heat-exchanger is connected to a refrigerant circuit, comprising a compressor 1, a second heat- exchanger 4 which is thermally connected to a fan system intended for blowing hot or cold air into the spaces to be heated or cooled respectively, a third heat-exchanger 2 which is connected to a tap hot water system, a con- tainer 11 of which is illustrated in the drawing, a circulation pump 8, a valve 9 and a shunt 10 which bypasses the valve.
  • the refrigerant circuit further includes an expansion valve 5, a drying filter 6, and a two-position refrigerant-flow reversal valve 3.
  • the refrigerant is preferably halogen, for instance one of the refrigerant types retailed under the name Freon.
  • valve 3 When the valve 3 is set to the first of its two posi ⁇ tions, the heating position, as illustrated in the drawing, refrigerant flowing from the compressor 1 passes through the heat-exchanger 2, the second heat- exchanger 4, the expansion valve 5, the filter 6, the first heat-exchanger 7 and back to the compressor 1.
  • the valve 3 When the valve 3 is set to the second of its two posi ⁇ tions, the cooling position, the input and output lines extend parallel with one another, instead of crossing one another, and the refrigerant flowing from the com ⁇ pressor 1 will pass through the third heat-exchanger 2, the first heat-exchanger 7, the filter 6, the expansion valve 5, the second heat-exchanger 4 and back to the compressor 1.
  • the heat pump includes control equipment, inter alia for starting and stopping the circulation pumps 8, 12 and the fan system co-acting with the heat-exchanger 4, for opening and closing the valve 9, and for adjusting the setting of the expansion valve 5.
  • the heat pump can be set into four different operational modes by means of the control equipment, namely;
  • the refrigerant heated by compression in the compressor 1 passes to the third heat-exchanger 2 and from there to the second heat- exchanger 4, in which the heat contained by the refri ⁇ gerant is transferred to the air blown by the fan system through the heat-exchanger and out into the spaces to be heated.
  • the refrigerant then passes through the expan ⁇ sion valve 5 and the drying filter 6, to the first heat- exchanger 7, where it takes-up heat from the liquid circulating in the pipe coil 13, prior to being again compressed in the compressor 1.
  • a heating and hot-water mode In this mode of the heat pump, the system settings are the same as those described under 1 above, but with the difference that electric current is now supplied to the pump 8 and the valve 9.
  • the circulation pump 8 When the tap water needs to be heated, a fact which is established by a thermostat (not shown) con- nected to the water container 11, the circulation pump 8 is started up.
  • water is taken from the container 11 or, if water is tapped from the system, from a cold water connection KV, and is caused to flow through and be heated in the third heat-exchanger 2.
  • the fan cooperating with the second heat-exchanger 4 will stop and the pressure in the outlet of the heat pump will increase, this increase pressure being detected by a pressure switch (not shown) mounted in the line between the compressor 1 and the third heat-exchanger 2.
  • This pressure switch functions to open the valve 9 and therewith make the whole of the power delivered by the heat pump available for producing hot water. The heat pump will continue to work until the pre-set tap-water temperature has been reached.
  • the shunt arrangement affords the additional advantage that as soon as the heat pump is started for room-heating purposes, maintenance-heating of the tap water in the container 11 is effected at the same time, since a certain amount of tap water is circulated through the heat-exchanger 2, the stationary pump 8 and the shunt 10 by a so-called ther osyphon effect.
  • the circulation pump 8 is started and the valve 9 is opened, while at the same time shutting down the circulation pump 12 in the pipe coil 13, wherewith the hole of the thermal power is taken-out through the third heat- exchanger 2.
  • the pump 12 is again started while throttling the circulation of hot tap-water through the heat-exchanger 2 at the same time.
  • a hot water mode In this mode of the heat pump, the reversal valve 3 is set to its heating position and the fan system is switched off. The heat pump is started-up when the need for hot water arises, and simultaneously starts the circulation pump 8. When the temperature in the pipe located between the compressor 1 and the third heat-exchanger 2 has reached a pre-set value, the valvj 9 is opened and the all of the system power available is used to produce hot tap water. The heat pump shuts down, when the hot tap water has reached a pre-set temperature.
  • the heat pump can be set to a mode in which it will function solely to heat a room or like confined space, to a mode in which it functions solely to heat tap water, or to a mode in which tap water is heated in combination with producing hot or cold air.
  • the heat pump can be modified within the scope of the inventive concept.
  • the heat pump can be complemented with an additional heat- exchanger for connection to radiators located in rooms or like confined spaces which only require to be heated and not to be air conditioned.
  • the shunt 10 can incorporate a valve for the purpose of controlling the flow through said shunt and for closing the shunt when the heat pump is set to mode 1 above.
  • the valve 9 can be constructed so as not to close fully, but to permit adjustments to be made to the flow of hot tap water there through.

Abstract

La pompe thermique décrite, qui sert à chauffer ou à refroidir des immeubles d'habitation ou des espaces fermés similaires, comprend un circuit réfrigérant pourvu d'un compresseur (1), un premier échangeur de chaleur (7) connecté thermiquement à une source de chaleur, un deuxième échangeur de chaleur (4) connecté thermiquement à un système de ventilateur, un troisième échangeur de chaleur (2) connecté thermiquement à un système de distribution d'eau chaude (11, VV), une vanne de détente (5) et une vanne d'inversion de courant réfrigérant à deux positions (3). La vanne (3) sert à inverser la séquence d'écoulement entre les diverses unités du circuit réfrigérant, selon que la pompe thermique doit assurer un chauffage ou un refroidissement. Indépendamment de son réglage sur chauffage ou sur refroidissement, la pompe thermique peut être amenée en même temps à produire de l'eau chaude de distribution ou à maintenir la température de l'eau sans qu'il soit nécessaire d'interrompre les conditions du moment de chauffage ou de refroidissement des pièces ou des espaces concernés, ce qui est rendu possible grâce au chauffage de l'eau de distribution directement dans le troisième échangeur de chaleur (2) et grâce au fait que l'eau de distribution est amenée à passer à travers un appareil de régulation, ayant la forme d'une pompe de circulation (8) et d'une vanne (9), ou à travers un shunt (10) qui contourne la vanne, durant son passage allant du troisième échangeur de chaleur (2) au réseau de distribution d'eau (VV).
