Description

[Detailed Description of the Invention] The present invention utilizes the air inside a sunroom as a heat source for heat exchange in a heat pump device, thereby making it possible to air condition the sunroom, living room, etc., and store heat in a heat storage tank. It relates to a heat utilization device that can utilize energy effectively, and more specifically, a heat source for a heat pump device unit that integrally incorporates an indoor heat exchanger, an outdoor heat exchanger, a compressor, a four-way valve, an expansion valve, a damper, etc. The present invention relates to a heat utilization device that utilizes air inside a sunroom, and further comprises a heat storage tank equipped with a heat exchanger and the heat pump unit connected to each other via a circulation pipe or the like.

Conventionally, a so-called heat pump device, which is a reversible refrigeration cycle, has one heat exchanger placed indoors and the other heat exchanger outdoors, exchanging heat with outdoor air or hot water from a solar collector, thereby making it possible to cool and heat indoors. . In addition, relatively large-capacity hot water supply or hot water heating is performed by storing hot water using a storage type hot water boiler or a solar collector, but hot water boilers have a large heating capacity and can obtain a large volume of hot water. Although it is easy to use, it has the disadvantage that it is inferior in energy saving performance. Although solar collectors are excellent in energy saving performance, the amount of heat supplied changes greatly, so even if you prepare a large capacity tank, the amount of energy used will be insufficient, especially in winter or in cold regions. It had the disadvantage that it was easy for a sufficient number of situations to occur. Therefore, in order to solve these problems, it is sufficient to install the respective devices,
The drawback was that it was uneconomical in terms of equipment costs.

The device according to the present invention is a completely new technology developed in view of the drawbacks of the conventional technology.In particular, the present invention is a heat pump device that is attached and fixed to a part of the sash frame of a sunroom or installed outdoors. The heat source medium for the heat pump is the air inside the sunroom, which has a much higher temperature than the outside air, and the condensation temperature is about 50℃, maintaining a high coefficient of performance. The present invention relates to a completely new heat utilization device that can perform both heat storage and heat storage.

To specifically explain one embodiment of the apparatus according to the present invention with reference to the drawings, in Figs. A steel floor base 1b is provided. Next, reference numeral 2 denotes a heat pump device unit constituting a main part of the apparatus of the present invention, which is attached and fixed to a part of the sash frame of the sunroom 1 substantially integrally with the sunroom wall. In particular, this unit 2 has an indoor heat exchanger 3, an outdoor heat exchanger 4, a compressor 5, a four-way valve 6, an expansion valve 7, and a switching damper 8, which are each integrally built in, and these are mutually well-known components. Connection piping is provided to operate the refrigeration cycle. As is clear from Fig. 1, the unit 2 has an intake port 2a that introduces air from inside the sunroom, an indoor air outlet 2b that blows out heat exchange air into the sunroom (including the living room), and an indoor air outlet 2b that blows the indoor air outside. An outdoor air outlet 2c for blowing out air, an air inlet 2d for introducing outdoor air, and an air outlet 2e for blowing out heat exchange air outdoors are provided, respectively. Above the indoor heat exchanger 3 is the air intake port 2a.
A blower fan 3a is provided adjacent to the air outlet 2e, and a blower fan 4a is also provided above the outdoor heat exchanger 4 adjacent to the air outlet 2e. Further, the switching damper 8 is provided between the air outlet 2b and the air outlet 2c, and selectively opens one of the air outlet 2b, 2c depending on whether cooling or heating in the sunroom is necessary or unnecessary. Furthermore, switching between the indoor air outlet 2b and the indoor air outlet is performed by providing a branch duct or a damper (not shown) at the outlet.

Next, 9 is a heat exchanger, which is a heat storage tank 1 installed on the floor base 1b of the sunroom 1 or under the floor of the living room.
0, and is connected to the compressor 5, four-way valve 6, etc. via a circulation pipe 9a, and is connected in parallel to the outdoor heat exchanger 4 via a switching valve 9b, so that it is similar to the heat exchanger. It exhibits a function. 11
12 and 13 are water supply or hot water tap pipes attached to the tank 10, 12a is an on-off valve, 13a is a pump, and 14 is a floor installed on the floor base 1b of the sunroom 1 as necessary. It is a hot water pipe for heating, and the tank 1 is supplied by the circulation pump 14a.
It is constructed so that hot water inside the room can be circulated.

To explain the operation of the device of the present invention using the heat pump refrigeration cycle shown in FIG. 2, when the four-way valve 6 is at the black line position, (A) the outdoor heat exchanger 4 or the heat exchanger 9 in the tank 10 (B)
The indoor heat exchanger 3 functions as an evaporator (endothermic action), and then when the four-way valve 6 is in the dotted line position, (A) the indoor heat exchanger 3 functions as a condenser, and (B) the outdoor heat Exchanger 4 or heat exchanger 9 acts as an evaporator.

Therefore, when the device of the present application is used as an air conditioner during summer, winter, mid-season, or severe cold season, or as a heat storage device for the tank 10, the following is the case.

(b) When performing air conditioning to cool living rooms during the summer or mid-season and storing heat in the tank, the four-way valve 6 is set to the black line position as described above, the switching valve 9a is switched to the heat exchanger 9 side, and the damper 8 is Dotted line position, fan 3
When the switch a is turned on, the warm air in the sunroom 1 is cooled from the intake port 2a by the fan 3a through the heat exchanger 3, and then returned to the sunroom 1 from the air outlet 2b.
Alternatively, air is blown into the living room to cool the room, while the heat exchanger 9 acts as a condenser to radiate heat, raising the temperature of the water in the tank 10 by the heat exchanger 9, and condensing it When the temperature rises to about 50° C., the switching valve 9a allows the heat exchanger 4 to perform its full condensing function.

(b) If you only want to store heat in the tank during the summer or mid-season, set the four-way valve 6 to the black line position, switch the switching valve 9a to the heat exchanger 9 side, set the damper 8 to the solid line position, and turn on the fan 3a. Then, the inside air in the sunroom 1 undergoes heat exchange in the heat exchanger 3, is cooled, and is discharged outdoors from the outlet 2c, and the heat exchanger 9 causes the water temperature in the tank 10 to rise by heat radiation. I can do it.

(c) When heating and air-conditioning a living room during the winter or mid-season, set the four-way valve 6 to the dotted line position, set the damper 8 to the dotted line position, switch the switching valve 9a to the heat exchanger 4 side, turn on the fan 3a, and turn the fan 3a on. When 4a is turned on, the heat exchanger 3 functions as a condenser and can blow out heated air into a sunroom or the like for heating. In this case, if only the fan 3a can be operated, if the temperature inside the sunroom is relatively high, it can be directly introduced into the living room to heat the room.
Energy can be used effectively.
In addition, heat storage operation is performed when sunlight is obtained during the day and the temperature inside the solarium is high, and when heating is required at night, heat pump operation is performed using the stored heat as a heat source, or direct floor heating is performed to heat the room. It can be heated.

(d) When performing heating and air conditioning during the coldest season, set the four-way valve 6 to the dotted line position, the damper 8 to the dotted line position, and the switching valve 9.
If the heat exchanger 9 is operated as an evaporator by switching a, hot air can be obtained from the heat exchanger 3, but the heat source is the hot water in the tank 10, and the heat exchanger 9 absorbs heat. This allows you to get comfortable heating even in the coldest months.

(E) When storing heat in the tank during winter or severe cold, set the four-way valve to the black line position, switch the switching valve 9a to the heat exchanger 9 side, set the damper 8 to the solid line position, and turn on the fan 3a to turn on the outside air. The heat exchanger 3 absorbs the heat in the sunroom 1, which is warmer than the sunroom 1, and the heat exchanger 9 in the tank radiates heat to raise the temperature of the hot water, and the air cooled by the heat exchanger 3 is discharged by the damper 8. Therefore, there is no need to cool the living room, etc., and heat can be stored in the tank 10.

(F) When the hot water in the tank 10 is used for hot water supply or floor heating, the hot water in the tank 10 is flowed through the pipes 13 and 14 by the pumps 13a and 14a, and used for hot water supply or floor heating. I can do it.

Since the device according to the present invention has the above-mentioned structure,
(1) The air inside the sunroom is warmer than the outside air due to solar heat, so it is very suitable as a heat source for a heat pump throughout the year, and heat can be stored in the heat storage tank extremely efficiently and effectively. ,
(2) Even in winter, the temperature inside the sunroom rises considerably during sunlight, so it is possible to use a fan as a blower and introduce it into the living room, increasing the energy saving effect. (3) ) Since the hot water in the tank can be used as a heat source for heating, there is no need to interrupt heating in the room even in winter, making it extremely practical. (4) Since the sunroom can be air-conditioned,
It has many features such as being able to cultivate ornamental plants, etc. (5) The heat pump device is a unit type and uses the air inside the sunroom, so it can be installed directly on the sash frame. .
