Definitions

  • This disclosure relates to a heat exchange type ventilation device with a humidifying function used in a living space or the like.
  • the heat exchange element 5e is a member for performing heat exchange (sensible heat and latent heat) between the exhaust flow 14 and the supply airflow 15.
  • the heat exchange element 5e is a total heat exchange element formed of heat transfer paper (heat transfer plate) based on cellulose fibers.
  • the material is not limited to this.
  • a moisture permeable resin film based on polyurethane or polyethylene terephthalate, or a paper material based on cellulose fiber, ceramic fiber, or glass fiber can be used. ..
  • a thin sheet having heat transfer properties and having a property of not allowing gas to permeate can be used. In this case, the heat exchange element 5e becomes a sensible heat exchange element.
  • the first heat exchanger 19b exchanges heat between the air RA blown from the blower fan 19a and the refrigerant flowing through the refrigerant circuit 21 (refrigerant gas whose high temperature and high pressure are increased by the compressor 20a described later). , A device that releases heat to the outside (outside the refrigerant circuit 21). That is, in the first heat exchanger 19b, the refrigerant dissipates heat. At this time, the refrigerant gas is condensed and liquefied under high pressure. In the indoor unit 19 (first heat exchanger 19b) during the heating operation, the temperature of the introduced refrigerant gas is higher than the temperature of the air. Therefore, when the heat is exchanged, the air RA is raised and the refrigerant gas is cooled.
  • the outdoor unit 20 is an outdoor unit installed in the outdoor 3.
  • the outdoor unit 20 includes a compressor 20a, an expander 20b, a second heat exchanger 20c, a blower fan 20d, and a four-way valve 20e.
  • the four-way valve 20e is a device (reversible valve) for switching the flow direction of the refrigerant in the refrigerant circuit 21. More specifically, the four-way valve 20e is connected between the compressor 20a and the first heat exchanger 19b (or the first heating unit 16) and between the compressor 20a and the second heat exchanger 20c. Then, the four-way valve 20e switches between the first state (during heating operation) and the second state (during cooling operation). In the first state (during heating operation), the refrigerant flows through the compressor 20a, the first heat exchanger 19b (or the first heating unit 16), the expander 20b, and the second heat exchanger 20c in this order. be.
  • the control unit 8 When the output capacity value for specifying the required humidification amount by the humidifying device 6 is equal to or less than the reference value (second reference value), the control unit 8 is the first of the first heating unit 16 and the second heating unit 17.
  • the air supply air 15 heated by the heating unit 16 is controlled to be humidified by the humidifying device 6. More specifically, when the output capacity value exceeds the first reference value smaller than the reference value (second reference value) and is equal to or less than the second reference value, the control unit 8 sets the first heating unit 16 and the second heating unit 8. Of the units 17, the air supply 15 heated by the first heating unit 16 is controlled to be humidified by the humidifying device 6.
  • the control unit 8 controls the humidifying device 6 to humidify the supply airflow 15 after heat exchange without heating.
  • the output unit 8c outputs the rotation output value received from the processing unit 8b to the humidifying device 6 (humidifying motor 6e of the humidifier 6d). Further, the output unit 8c outputs the heating output information received from the processing unit 8b to the first heating unit 16 and the second heating unit 17, respectively. Then, the humidifying device 6 executes the humidifying operation operation according to the rotation output value output from the output unit 8c. Further, the first heating unit 16 and the second heating unit 17 execute on or off of the heating operation operation based on the heating output information output from the output unit 8c.
  • step S03D when the output capacity value exceeds the second reference value (Yes in step S03C), the processing unit 8b performs the processing in step S03E. That is, the processing unit 8b has the rotation output value (third rotation output value shown in FIG. 5) corresponding to the output capacity value exceeding the second reference value and the heating output information of the first heating unit 16 and the second heating unit 17.
  • the information for turning on the driving operation (second on information) is specified (step S03E).
  • the first reference value and the second reference value are values defined corresponding to the maximum rotation speed that can be set in the humidifying motor 6e of the humidifying device 6 in each state.
  • the heat exchange type ventilator with a humidifying function is useful as a heat exchange type ventilator capable of exchanging heat between indoor air and outdoor air as having a humidifying function and a heating function. be.
