Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat collecting panel for a heat pump type air conditioner or the like that uses solar heat as a heat source for heating and air as a heat source for cooling, and particularly relates to a heat collecting panel for a heat pump type air conditioner etc. that uses solar heat as a heat source for heating and air as a heat source for cooling. To provide a heat collecting panel for replacement, which can freely control solar heat reception throughout the year.

Conventionally, the heat collection panels of heat pump air conditioners, which use solar heat as the heat source for heating and air as the heat source for cooling, are made by forming two thin metal plates using the roll bonding method, and forming refrigerant flow channels that become thin tubes. Formed flat plates are often used.

However, these flat heat collecting plates are fixed at a fixed angle to the sunlight and receive solar heat when heating, and radiate heat when cooling.
Since the height of the sun in winter and the height of the sun in summer are different, heat exchange efficiency has been disadvantageous.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 1 and 2. In the figure, 1 is a compressor unit that houses a compressor, a four-way valve, a user-side heat exchanger, an expansion valve, etc., and 2 is a heat storage tank connected to the compressor unit 1 through a pump 3 and a connecting pipe 4. be. Cold and hot water is sent from the heat storage tank 2 by a pressure pump 7, and a load side 6 is led out, and from the compressor unit 1, a plurality of water are sent via piping 11 and a distributor 10. A solar heat collecting device 8 consisting of a heat collecting panel 9 is derived.

FIG. 2 is a detailed perspective view of the heat collecting panel 9, which includes a pipe 12 through which refrigerant flows in the center, a pipe main body 13, and a right engaging portion 1 that is extruded integrally with the pipe main body 13.
4. It has a left engaging part 15. Said right engaging part 1
4 is closely engaged with a movable fin 16 made of extrusion molding that moves like a flap,
Similarly, movable fins made of extrusion molding that move like flaps are tightly engaged with the left engaging portion 15, and these movable fins 16 and 17 are approximately 90 degrees wide with the left and right engaging portions 14 and 15 as fulcrums.゜I try to control it freely so that it can move.

In the above configuration, during cooling, the operation is mainly performed at night, and the refrigerant compressed by the compressor unit 1 flows through the heat collecting panel 9 through the piping 11, and here,
It exchanges heat with the outside air, radiates heat to the atmosphere, and the condensed liquid passes through the distributor 10 and returns to the compressor unit 1 as a liquid refrigerant.During heating, it mainly operates during the day.
The refrigerant compressed by the compressor unit 1 is condensed and expanded by the heat exchanger on the user side in the unit, and then the liquid refrigerant passes through the pipe 11', passes through the distributor 10, flows through the heat collection panel 9, and then flows through the heat collection panel 9. At step 9, the refrigerant absorbs heat using solar heat and air heat as a heat source and vaporizes, and the refrigerant gas returns to the compressor unit 1 through a pipe 11. Therefore, in this heat collecting panel 9, movable fins 16, 17 are used during winter heating.
is set to the solid line position so that sunlight A can be received sufficiently. Also, during summer cooling, the movable fin 1
6 and 17 to avoid sunlight A and change their orientation to the dotted line position. In this way, when changing the direction to the sunlight, the extruded right engaging part 1
4. The pipe main body 13 having the left engaging part 15 and the movable fins 16 and 17 are held so as to fit together, and the angle can be freely controlled in winter and summer.

In this way, the present invention aims to direct the movable fins toward the sunlight in order to most effectively evaporate the refrigerant in the heat collecting panel using solar heat as a heat source during winter heating, and to direct the movable fins toward the sunlight to avoid solar heat during summer cooling. In order to condense refrigerant as a heat source, this heat collection panel has movable fins that can be switched to point in the same direction as sunlight, as shown by the dotted line, so it can receive light most efficiently during winter heating. , during summer cooling, even if you do not mainly operate at night,
It will also be possible to drive during the day. In addition, it can be installed freely without limiting the installation angle during installation, and wind pressure can be minimized in times of strong winds, making the use of solar heat effective throughout the year and efficient use as an air heat exchanger. It can be done well.
