Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a daylighting device using a heat pump.

BACKGROUND OF THE INVENTION As shown in FIG. 7, this type of daylighting device has a double-glazed space 9a provided in a window of a house, consisting of an outer glass 9 in contact with the outside air and an inner glass 10 in contact with the interior of the house. It is equipped with a fan 8 that circulates air and a blind 16 that adjusts the brightness of sunlight.

Then, the fan 8 is turned to take in indoor air from the intake port 9b at the bottom of the window, and exhaust it to the outside from the exhaust port 9C above the window through the double-glazed space 9a.

Since the temperature of the inner glass 10 approaches room temperature, temperature changes in the window portion due to sunlight and the like are alleviated.

In other words, the amount of heat exchanged between the inner glass 10 and the room is significantly smaller than the amount of heat exchanged between the outside glass 9 and the outdoors, so the heat insulation effect at the window part is lower than that of glass windows in ordinary houses. It was starting to improve.

Furthermore, by adjusting the blinds 16 installed in a 9m double-glazed space, the illuminance of the sun's rays can be varied, reducing the air conditioning load near windows and preventing excessive illumination. It is designed to prevent discoloration.

Problems to be Solved by the Invention However, with the above configuration, indoor air is released to the outdoors through the double-glazed space 9a.
Heat dissipation and cooling capacity loss from a room that has been adjusted for comfort cannot be avoided.

On the other hand, although it will not be discussed here, even if a duct for switching the wind direction is installed under the fan 8 to return air back into the room, energy loss from inside the room cannot be improved, and even in the vicinity of the window. Wind with unstable temperatures flows through the air, causing discomfort.

Furthermore, in seasons when the amount of sunlight is high, the blinds 16 block sunlight, preventing sunlight from entering the room and exhausting solar heat to the outside, making it impossible to utilize solar energy effectively.

Therefore, there was a problem in that these energy losses were constant and the energy saving effect was small.

The present invention solves these problems, and aims to prevent heat radiation loss and cooling capacity loss from indoors, store and effectively utilize solar energy while maintaining comfortable air conditioning, and significantly improve energy saving effects. shall be.

Means for Solving the Problems In order to solve the above problems, the heat pump type daylighting device of the present invention consists of an outer light-transmitting plate in contact with the outside air and an inner light-transmitting plate in contact with the interior of the room, with a space formed between them. A light transmitting plate, a fan that circulates outdoor air in the space of the double light transmitting plate, a heat collecting and dissipating fin provided between the double light transmitting plate and having an angle adjustment means, and a heat transfer relationship with the heat collecting and discharging fin. A refrigerant pipe is installed in the pipe, and the pipe is equipped with a compressor and a four-way valve.

A refrigeration cycle is constructed by connecting a heat storage device equipped with a heating mechanism, a heat exchanger in a heat transfer relationship, and a pressure reducing device equipped with a check valve in parallel in a ring shape.

Function The present invention has the above-mentioned configuration, so that it can be installed in a double-glazed space.
In order to circulate outdoor air and adjust the temperature in the refrigeration cycle so that the temperature of the inner glass approaches room temperature, energy loss from indoors is ensured without affecting the comfortably adjusted indoor air conditioning conditions. can be lowered to

In addition, solar energy from sunlight can be effectively collected by the heat collecting and radiating fins and pipes installed between the double-glazed windows, reducing the air conditioning load near windows during seasons with high solar radiation and preventing excessive illumination. This not only prevents heat loss but also significantly improves the energy saving effect of solar energy storage.

Furthermore, since the angle of the heat collecting and dissipating fins can be changed using an angle adjustment mechanism, heat collection, heat dissipation, and lighting can be performed appropriately (1).

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIGS. 1, 2, and 3, 9 is a transparent outer glass, 10 is a transparent inner glass that forms a space 18 between the outer glass 9, and these constitute the windows of the house 17. Also, 6
is a pipe through which refrigerant flows horizontally in multiple stages in the space 18,
7 is a heat collection and radiation fin that transfers heat to the vibro, and 8 is a fan whose rotation speed can be controlled to circulate outdoor air into the space 18. Reference numerals 9b and 9c are an intake port 9b and an exhaust port 9c provided at the lower and upper portions of the outer glass 9 to communicate with the space 18.

The vibro is connected to a compressor 1, a four-way valve 2, a heat storage device 11 equipped with a heating mechanism 12, and a pressure reducing device R4 equipped with a heat exchanger 3 and a check valve 5 in parallel in a heat transfer relationship. , making up the refrigeration cycle. Moreover, the inner glass 10
is completely isolated from the indoor air to prevent indoor air from escaping to the outdoors. 13 is an indoor temperature sensor, 1
4 is an inner glass temperature sensor that detects the temperature in the vicinity of the inner glass 10, and 15 is a controller that controls the rotation speed of the fan 8 based on the signals from both temperature sensors 13 and 14.

In the above configuration, the effect of reducing indoor energy loss will be roughly divided into summer and winter and will be explained below.

In the summer, when the outdoor temperature is generally higher than the room temperature, indoor rooms are cooled down to a comfortable temperature by air conditioners, but this cooling capacity loss is large near windows.

However, in this embodiment, the vibro and heat collecting and radiating fins 7 connected to the refrigeration cycle absorb heat from the high temperature outdoor air in the space 18 and cool it, thereby bringing the temperature of the inner glass 10 closer to room temperature. Prevents cooling capacity loss near windows. Moreover, there is an effect that thermal energy is stored in the heat storage device 11 which is in a heat transfer relationship with the refrigeration cycle.

At this time, the operation of the refrigeration cycle is as shown by the solid line arrow in Fig. 1. The refrigerant in a high temperature and high pressure state discharged from the compressor 1 flows through the four-way valve 2 and enters the heat exchanger 3 in a heat transfer relationship. Thermal energy is stored in a heat storage device 11 located at Here, the liquefied and condensed refrigerant becomes a low temperature and low pressure state when passing through the pressure reducing device 4, and flows through the vibro provided between the double panes of glass. At this time, since the fan 8 is being driven, air is sucked in through the intake port 9b, exhausted through the exhaust port 9C, absorbs heat from the hot outdoor air circulating in the double-glazed space 18, and evaporates. It is then sucked into the compressor 1 again and the cycle is repeated.

By the way, the heat collecting and dissipating fins 7 designed to efficiently transfer heat to the vibro not only improve the heat collecting effect in the refrigeration cycle, but also serve as heat collecting fins that collect solar energy from the strong sunlight in the summer. It has the effect of increasing face quality. In this example, the outdoor side of the heat collecting and dissipating fins 7 is colored in black, which has a large heat collecting effect. The heat stored here can be used as another heat source, but this will not be described in particular.

At the same time, the heat collecting fins 7 have the effect of blocking sunlight to some extent, preventing excessive illuminance, and maintaining comfortable indoor illuminance.

On the other hand, in the winter when the outdoor temperature is lower than the room temperature, the room is heated to a comfortable temperature by heating equipment, but there is a large loss of heat radiation from the room near the windows.

However, in this embodiment, when solar radiation is relatively strong during the day and solar heat is supplied, heat is stored in the heat storage device 11 by the refrigeration cycle operation during heat absorption, as in the summer. After that, at night, the vibro and heat collecting fins 7 radiate heat from the double glass space 18 to the cooler outdoor air.
heating and bringing the temperature of the inner glass 10 closer to room temperature,
This has the effect of preventing heat radiation loss from the vicinity of the window to the outdoors.

By the way, when it is not possible to heat the air in the double-glazed space due to the amount of stored heat being small during periods of low solar radiation such as during cloudy days or in the evening, the electric heater etc. provided in the heat storage device 11 may be used. Heat it in advance using the heating mechanism.

The operation of the refrigeration cycle in the winter is performed by switching the four-way valve 2 to perform a reverse cycle of the summer operation, as shown by the broken line arrow in FIG. In this reverse cycle, the high-temperature, high-pressure refrigerant discharged from the compressor 1 heats the air in the double-glazed space 18 via the vibro and heat collecting and radiating fins 7, and then in the heat exchanger 3. Heat storage device 11
It absorbs heat and is sucked into the compressor 1 again.

Furthermore, regarding the configuration of the heat collecting and dissipating fins 7 and the vibro, the second
This will be explained in detail with reference to FIGS. 4 and 5.

As mentioned above, 6 is a pipe and 7 is a heat collecting and radiating fin, and these have a good heat transfer relationship. The heat collecting and dissipating fins 7 are configured to be able to rotate around the vibro in the circumferential direction while maintaining this good heat transfer relationship, and this rotation is electrically controlled by a motor 19 provided at one end of the vibro. will be implemented. In addition, there are several other vibros, including a power transmission bell) 2
The rotational force of the motor 19 is transmitted through the vibro 0, and the vibro is set to be displaced at the same angle as the vibro. The motor 19 transmits a signal from a remote controller 21 provided indoors to the controller 15, and the controller 15 controls the motor 19 to drive the heat collecting and dissipating fins 7 at an optimum angle.

Therefore, with the above configuration, the heat collecting and dissipating fins 7 act to always form the maximum heat collecting area as the height of the sun changes depending on the season and time, and collect solar energy to the maximum extent. There is an effect.

Furthermore, since the angle can be finely adjusted to the user's preference using the remote control 21, it is possible to not only prevent excessive illuminance of sunlight but also to freely change the amount of daylight.

Next, another embodiment of the present invention will be described using FIG. 6. In FIG. 6, parts that are the same as those of the previous embodiment are given the same reference numerals, detailed explanations are omitted, and differences will be mainly explained.

The control means for the angle adjustment mechanism of the heat collecting and dissipating fins 7 is different from the above embodiment, and the signal transmitted to the controller 15 is controlled by the remote controller 2.
1 instead of the sunlight sensor 22.

According to this configuration, the sunlight sensor 20 accurately and sequentially detects the high position of the sun and optimizes the angle of the heat collection and radiation fins 7, so it is possible to automatically collect the maximum amount of solar energy. Excellent energy saving effect even when the user is absent.

Although it is easily possible to manually adjust the angle of the heat collecting and dissipating fins 7, this will not be discussed here.

Effects of the Invention As described above, according to the heat pump type lighting device of the present invention, the following effects can be obtained.

(1) Outdoor air is circulated through the space of the double light-transmitting plate made up of the inner light-transmitting plate and the outer light-transmitting plate, and the temperature is controlled using a refrigeration cycle so that the temperature of the inner light-transmitting plate approaches room temperature. Since the adjustment is made, it is possible to reliably reduce energy loss (heat radiation, cooling capacity loss, etc.) from a room that has been adjusted for comfort.

(2) A refrigeration cycle is installed in the space of the double translucent plate (7 pipes and their heat collecting and radiating fins can efficiently absorb solar energy from sunlight and store it as thermal energy. It can be used as a heat source, especially in seasons with high solar radiation.
Energy saving effects can be increased by utilizing inexhaustible solar energy. It is also possible to reduce the air conditioning load near the window.

(3) In addition, the heat collection and radiation fins equipped with an angle adjustment mechanism,
Since it is also possible to block strong solar rays, it is possible to prevent excessive illuminance in the room and maintain a comfortable indoor illuminance desired by the user.

(4) Furthermore, it is also possible to use the thermal energy stored in the heat storage device during the daytime or summer when the amount of solar radiation is high to heat the outdoor air in the double transparent plate space during winter nights when the outdoor temperature is low. Therefore, almost no separate heat source is required to obtain the above effects, and the running cost of operating the device is extremely low.

(5) Furthermore, the angle of the heat collecting and dissipating fins is adjusted using signals from a remote control installed indoors or a sunlight sensor that tracks the sun's high position, so the heat collecting and dissipating fins always maintain the maximum heat collecting area. This enables effective storage of solar heat, as well as remote control and automatic adjustment of the angle of the front heat collection fins.
