Further, by providing the suction port 20a, it is possible to prevent the equipment provided in the indoor unit 2b of the heat pump from being heated up, and the equipment can be operated without any burden.

  Next, the outdoor unit 2a of the heat pump and the indoor unit 2b of the heat pump will be described in detail. The outdoor unit 2a of the heat pump accommodates the compressor 5 and the heat exchanger 6 therein, and the indoors of the heat pump The machine 2b has a structure that houses the expansion valve 7 and the heat exchanger 8. And warm air or cold air is produced | generated via this compressor 5, the heat exchanger 6, the expansion valve 7, and the heat exchanger 8. FIG.

  If it demonstrates in detail, when the temperature of external air is low, when performing heating operation, the heat exchanger 6 acts as the condenser in the outdoor unit 2a of the heat pump. Conversely, when the temperature of the outside air is high, the heat exchanger 6 acts as an evaporator when performing the cooling operation. Note that the outdoor unit 2a of the heat pump can use any medium such as gas or liquid when the heat source taken in from the outside air is used as the refrigerant, and considers thermal conductivity and the like. In addition to the method of using the heat accumulated in the soil, the heat source includes a method of using groundwater heat (groundwater source) that stays (accumulates) in the ground. When this method is employed, By pumping up the (groundwater source) with a pump or the like (not shown) and taking it into the outdoor unit 2a of the heat pump, the heat loss is suppressed and effective utilization is achieved.

  The heat pump indoor unit 2b acts as an evaporator when the heating operation is performed as described above. Conversely, when performing the cooling operation, the heat exchanger 8 acts as a condenser. Then, the refrigerant is passed through the indoor unit 2b of the heat pump and the refrigerant pipe 3, and the outdoor unit 2a of the heat pump is circulated. The refrigerant sent from the outdoor unit 2a of the heat pump to the indoor unit 2b of the heat pump is subjected to heat exchange by the heat exchanger 8, and is heated or cooled from the discharge port 20 provided in the indoor unit 2b of the heat pump. Is discharged.

  A duct 21 can be added to the discharge port 20. The shape of the duct 21 can be changed, and warm air or cold air discharged from the discharge port 20 can be discharged to a predetermined location by the duct 21 and the temperature inside the house 1 can be easily adjusted. Can do. The duct material may be various ducts such as aluminum and resin, but any material can be used as long as it is a member that can withstand high temperature and pressure. As described above, by providing a suction port (not shown) in the duct 21, the inside air staying in the house 1 sucked from the suction port can be comprehensively taken into the circulation fan 4.

The protective guard 4e has a bracket 4g extending substantially equally over the four sides toward the casing 4a.

  Further, as another example of the circulation fan 4, a gap S is provided in the casing 4a, the introduction of outside air is urged from the gap S, and warm air or cold air sucked from the suction side is fed to the discharge side while mixing. Then, the mixed outside air is rectified by the rectifying plate 4f and is pumped through the fan 4b. That is, by providing the gap S in the casing 4a, since the outside air staying (floating) around the casing 4a is sucked in, the amount of blown air increases, and more stable generation of warm air or cold air flow than before, A wide range of warm air or cold air flow is ensured, and the warm air or cold air can contribute to the expansion of the entire house. The gap S is provided according to the length of the casing 4a. However, it is necessary to consider securing the strength of the member and facilitating fixation to other members.

  Next, the suspension means 9 and the adjustment means 9a will be described. The suspension means 9 is parallel to the bracket 4g provided on the protective guard 4e of the circulation fan 4 and the short direction 1b of the ceiling surface 1c of the house 1. The circulating fan 4 is supported in a stable state with the installed beam 10 reliably. And this suspension means 9 is provided easily so that it can be moved according to the area of the house 1 so that the number and location of the circulation fans 4 can be changed and moved. The suspension means 9 may be a method of using a roller chain, a sprocket, or the like in addition to providing the support rod 90 via a fixing means such as a screw on the casing 4a. If it can be supported, the structure is unquestioned. The beam 10 can replace the beam 10 by using the beam of the house 1, thereby reducing the number of parts and facilitating the attachment / detachment work.

  Next, the adjusting means 9a will be described. The adjusting means 9a, when the support rod 90 is taken as an example, has a member for expanding and contracting the support rod 90, an expansion rod 91. When the telescopic rod 91 is expanded and contracted, the support rod 90 is held and the support rod 90 is rotated. By this rotation, the telescopic rod 91 is extended, so that the support rod 90 is rotated in the reverse direction by a desired length. By this reverse rotation, the support rod 90 and the telescopic rod 91 are pressed against each other, and the telescopic rod 91 can be stopped (fixed) at a predetermined position without causing any deviation.

  Next, the other circulation fan 40 provided separately from the circulation fan 4 will be described. The structure of the circulation fan 40 is the same as that of the circulation fan 4, and the suspension means 7 and the adjustment means 8 are provided. And it is provided in the circulation fan 4 and the longitudinal direction 1a of the house 1 in the horizontal direction. Therefore, when a plurality of circulation fans 4 are provided in the vicinity of the discharge port 20, the same number of other circulation fans 40 are installed in the longitudinal direction.

  And in addition to said structure, the introduction fan 101 which introduces external air is provided in one wife surface 100a of the house 1, for example, and the introduction of external air is promoted substantially equally from the whole house. Moreover, the structure which provides the ventilation fan 102 which accelerates | stimulates discharge | emission of external air in the other wife surface 100b of this house 1 is also possible. The introduction fan 101 and the ventilation fan 102 are used in combination with the outdoor unit 2a of the heat pump and the indoor unit 2b of the heat pump, so that effects such as easy temperature adjustment in the house 1 and saving of running costs can be expected.

  Although not shown, the introduction fan 101 is installed on the ceiling surface 1c and the space 1d of the house 1, and the warm air or cold air is accelerated and / or increased by ensuring a wide flow of warm air or cold air. In this example, synergistic properties are possible. As a result, there is practicality such that an external air introduction type forced ventilation system can be constructed or temperature adjustment can be proposed.

  Next, the flow of warm air or cold air (cooling / heating method) of the house 1 based on this structure will be described below.

  First, the case where the outside air temperature is low such as during snowfall or at night will be described as an example. The outside air staying in the vicinity of the house 1 (including heat sources such as earth heat source or water cooling heat source) is outside the house. It is taken into the outdoor unit 2a of the house from the machine 2a. The taken-in outside air evaporates when the heat exchanger 6 functions as an evaporator. The evaporated outside air is gasified and becomes a refrigerant. Then, this refrigerant is compressed by the compressor 5 and becomes a high-temperature and high-pressure refrigerant. The high-temperature and high-pressure refrigerant passes through the refrigerant pipe 3 and is sent to the indoor unit 2b of the heat pump, and is discharged into the house 1 as warm air from the discharge port 20 of the indoor unit 2b of the heat pump. This warm air is sent from the circulation fan 4 to the other circulation fan 40, and the circulation fan 4 is operated in order to generate a flow of warm air in the longitudinal direction in the house 1 and in a substantially horizontal direction. In order to operate the circulation fan 4, a fan motor 4c is operated via a base part 4d, and a rotation shaft (not shown) is rotated by this operation, and the fan supported on the rotation shaft is supported. 4b rotates. And by this rotation of the fan 4b, warm air is sucked in from the suction side, passes through the inside of the casing 4a, and is discharged from the discharge side. Further, in addition to the warm air discharged from the discharge port 20, the warm air remaining in the house 1 is also discharged while mixing (involved together). The warm air discharged from the discharge side is sent to another circulation fan 40. Since the other circulation fan 40 has the same structure as the circulation fan 4 and performs the same function (operation or stop), the warm air generated from the indoor unit 2b of the heat pump is The circulation fan 40 generates a flow of warm air or cold air in the same longitudinal direction as that of the house 1 as well as a substantially horizontal direction, and generates a desirable temperature environment for the crop growing in the house 1. Because it can be scattered throughout the entire area, it is possible to minimize the loss of heat from the warm air because it is fully utilized from the blower and instantaneously scatters from the blower to the entire interior of the house 1. To improve the heating effect. In addition, the arrow of FIG. 2 shows the flow of warm air or cold air.

  The above has been described by taking as an example the case where the outside air temperature is low such as during snowfall and at night, but conversely, when the outside air temperature is high such as during summer and during the day, the outlet of the indoor unit 2b of the heat pump Cold air is discharged from 20. In the same manner as described above, this cool air is mixed with the inside air in the house 1, and the flow of the cool air in the longitudinal direction and the substantially horizontal direction in the house 1 through the circulation fan 4 and the other circulation fan 40 and the wide area. As a result, a cool air flow is ensured, the cool air is uniformly expanded throughout the house 1, and the same effect as described above can be produced.

  Switching when performing a heat pump operation for heating operation or cooling operation, and operation of each device such as the circulation fan 4 and the other circulation fan 40 are controlled by a timer or the like and a greenhouse temperature for detecting temperature and humidity. A control panel 11 such as a sensor is provided at appropriate locations inside and outside the house 1 to ensure a warm or cool air flow in a substantially horizontal direction in the longitudinal direction 1a and a wide flow of warm or cold air in the longitudinal direction 1a. Or the effect that cold air expands is produced.
