Description

[Detailed explanation of the invention] (Field of industrial application) This invention is attached to a heat pump type air conditioner that also has heating and cooling functions, so that a sufficient heating effect can be obtained in winter, etc., but the cooling effect is lost in summer, etc. This article relates to an external heating device for an air conditioner that is designed to prevent damage.

(Conventional technology) Heat pump air conditioners that combine heating and cooling are
In winter, when the outside air temperature drops to around 0° C., the heating capacity decreases significantly. For this reason, there were difficulties in practicality when using it in cold regions, and its widespread use was hindered. However, in this type of heat pump air conditioner that is currently in general use, no measures have been taken to solve the above problems.

(Problem that the invention aims to solve) Therefore, this invention is attached to a heat pump type air conditioner that combines heating and cooling, and supplements its heating capacity in winter, etc., so that a sufficient heating effect can be obtained even in cold regions. The purpose of the present invention is to provide an external heating device for an air conditioner, which has the purpose of increasing its practical value by preventing its cooling effect from being impaired even if it is not removed during summer, etc. .

(Means for Solving the Problem) This invention provides an opening 2 at the front end of the body 6 that fits the air intake port 1 in, for example, the outdoor unit A of a heat pump type air conditioner, and connects the opening 2 to the outdoor unit A. The heater B can be attached to the outdoor unit A by joining it to the air intake port 1 of A, and the outside air inlet 4, which can be freely opened and closed by a damper 3, is bored in the body 6 and closed during heating. The air intake port 1 of outdoor unit A is
A gas burner 7 is provided in the container 6 to directly guide the intake air from the air inlet 8 on the back of the container so as not to affect the cooling capacity. A heat exchanger 5 is provided so that the air heated and heated by the heat exchanger 5 is guided to the air intake port 1 of the outdoor unit A to assist the heating capacity.

(Function) During heating in winter, etc., the damper 3 closes the outside air inlet 4 and the gas burner 7 is ignited to exchange heat with the intake air that is drawn in from the air inlet 8 on the back of the vessel 6 and passes through the heat exchanger 5. The device 5 heats the air to an appropriate temperature and guides it to the air intake port 1 of the outdoor unit A to assist its heating capacity.In addition, during cooling in summer etc., the outside air intake port 4 is heated by the damper 3.
When the outside air inlet 4 is opened by unblocking the outdoor air inlet 4, sufficient outside air required for cooling will be introduced from the outside air inlet 4 and directly led to the air intake 1 of the outdoor unit A, which will impede the cooling effect. It never happens.

(Example) Hereinafter, an example of the external heating device for an air conditioner according to this invention will be described based on the drawings.

First Embodiment In FIGS. 1 to 3, the embodiment is applied to a separate heat pump air conditioner, where A is the outdoor unit of the heat pump air conditioner, 1 is the air intake port of the outdoor unit A, and B is the outdoor unit of the heat pump air conditioner. With the heated air of this invention, an opening 2 that fits the air intake 1 of the outdoor unit A is provided at the front end of the box-shaped container 6, and the opening 2 is connected to the air intake 1 of the outdoor unit A.
It can be attached and fixed by a flange 9 on the periphery, and there are hinges 1 at the top and bottom of the front part of the vessel body 6.
an outside air inlet 4 that can be freely opened and closed by dampers 3 and 3' that are freely rotatable around 0 and 10';
4' to prevent the outside air inlets 4, 4' from being blocked by the dampers 3, 3' during heating and hindering the heating capacity, and during cooling, the dampers 3, 4'
By unblocking and opening 3', outside air is led directly from the outside air inlets 4, 4' to the air intake 1 of the outdoor unit A, so that the cooling capacity is not affected in any way, and A heat exchanger 5 is installed at the rear part of the vessel body 6 to heat and raise the temperature of intake air that is heated by a gas burner 7 and is drawn from an air inlet 8 on the back side of the vessel body. The heated air is guided to the air intake port 1 of the outdoor unit A to assist the heating capacity. The heat exchanger 5 includes a heat pipe 5a and a large number of heat absorption fins 5.
b, which functions to collect and radiate heat. 11 is a gas supply pipe to the gas burner 7, and the gas supply pipe 11 is equipped with a control section 12 and a gas control valve 13. 14 is an air supply port for taking in combustion air from the gas burner 7, and 15 is an exhaust port for discharging combustion exhaust gas from the gas burner 7.

Figure 3 shows an installation example of a separate heat pump type air conditioner, in which the indoor unit C is installed at a suitable location on the side wall 16 of the room D, and the outdoor unit A equipped with the heater B is installed on the ground etc. outside the room E. , indoor unit C and outdoor unit A are connected by reciprocating conduits 17 and 18.

In the above configuration, during heating in winter, etc., the dampers 3, 3' close the outside air inlets 4, 4' (see the solid line position in Figure 1), and the gas burner 7 is ignited and burned to heat the heat exchanger 5. , the air that is taken in from the air inlet 8 on the back of the container 6 and passes through the heat exchanger 5 is heated to an appropriate temperature by the heat exchanger 5 and guided to the air intake 1 of the outdoor unit A (first
(see arrow a in the figure) assists in its heating capacity.

Next, when cooling the air conditioner in the summer, etc., damper 3,
When the outside air inlets 4, 4' are unblocked by the outside air inlet 3' and opened (see the position indicated by the chain line in Figure 1), the air required for cooling by the outdoor unit A is transferred to the outside air inlet 4, 4'. 4, 4' and directly to the outdoor intake port 1 of outdoor unit A (see arrow b in Fig. 1).
Even if the heater B is attached to the air intake port 1 of the air conditioner, the cooling effect is not affected in any way.

In the heating and cooling operation described above, the blinking of the gas burner 7 of the heater B and the opening and closing of the dampers 3 and 3' are
It would be advantageous in terms of implementation if this could be done by remote control operation.

Second Embodiment In FIG. 4, an opening 2 that fits the air intake 1 of the outdoor unit A of a heat pump type air conditioner is provided at the front end of the body 6, and the opening 2 is connected to the air intake 1 of the outdoor unit A. Heater B
can be installed on the outdoor unit A, and an outside air inlet 4 is obliquely provided on the lower surface of the container body 6, which can be freely opened and closed by a damper 3 that is rotatably provided with a hinge 10 as a fulcrum. During heating, the outside air inlet 4 is blocked by the damper 3 to prevent it from interfering with the heating capacity, and during cooling, the damper 3 is unblocked and opened to allow outside air to flow through the air intake of the outdoor unit A. A heat exchanger 5 is installed in the rear part of the container body 6 so as not to lead directly to the outside air inlet 4, and the cooling capacity is not impaired. The air taken in from the port 8 is heated and heated to be guided to the air intake port 1 of the outdoor unit A to assist the heating capacity.

(Effects of the invention) As explained above, this invention can be attached to a heat pump type air conditioner to supplement its heating capacity in the winter, etc., to obtain a sufficient heating effect even in cold regions. Since the cooling effect is not impaired even if the air conditioner is not removed, it is especially effective for use in cold regions, so its widespread use will not be hindered, and it will not interfere with existing air conditioners on the market. It is economical because it can be used as an accessory without any modification or modification.Furthermore, since it is attached to the air intake of the air conditioner, no combustion exhaust gas is released into the room. Therefore, it is extremely superior in terms of environmental hygiene.
