Description

  The present invention relates to a cold air supply device using cold air generated during operation of a heat pump type hot water heater (hereinafter referred to as an eco water heater).

  Conventionally, heat pump water heaters using chlorofluorocarbon as a refrigerant have been used, but chlorofluorocarbon gas has been banned because it destroys the ozone layer, and eco water heaters using natural refrigerants such as carbon dioxide are now widely used. Progressing.

  By the way, this eco water heater heats and stores tap water with the energy obtained by exchanging heat with the atmosphere, and the air that has been absorbed and cooled to low temperature is directly diffused into the atmosphere. Therefore, a system has been proposed in which this cold air is supplied to an indoor toilet, a washroom, a dressing room, a bathroom, etc., and is simply cooled in a spot manner (see, for example, Patent Document 1).

  However, eco water heaters installed in ordinary houses use midnight power that is supplied at a low cost of about one third of the normal time from 23:00 to 7:00 when the demand for commercial power decreases. There are many cases that operate, and in this case, the washroom and the like are cooled during a time when no person is active, so there is a problem that a special merit cannot be obtained in a general household. However, there is a merit that the hot spring facility and spa facility of the additional cooking method can be used for cooling the guest room regardless of day or night.

  The present invention includes a cool air supply unit that introduces cold air cooled by exchanging heat with a refrigerant in an eco water heater, and an adjustment unit that adjusts the cooling capacity of the cool air introduced into the house. It is an object of the present invention to provide a cold air supply apparatus that can contribute to energy saving by using the cold air discharged from the eco water heater, and that can freely and easily adjust the inflow cold air amount.

  For this reason, the cold air supply device of the present invention has a heat exchanger that absorbs latent heat in the atmosphere, stores hot water obtained by heating city water with the heat exchanger in a tank, and supplies hot water. A first feature is that an exhaust duct for introducing cool air obtained by heat exchange in the heat exchanger into the building indoors is provided at the cold air outlet. A second feature is that the exhaust duct end of the exhaust duct is provided apart from the building wall. A third feature is that a bellows-type shutter is provided between the exhaust duct and the building interior.

(1) Since the cool air discharged from the eco water heater is guided indoors and used for cooling, it can contribute to energy saving. In particular, when using midnight power, the room temperature can be sufficiently cooled by the energy level of the exhaust air in the time zone from 11:00 pm to 7:00 am. Moreover, it is possible to prevent overcooling by the air volume adjusting means and adjust to a comfortable temperature environment, and it can be suitably used to obtain a good night's sleep especially in summer and general homes.
(2) Since the cool air is directly introduced from the eco water heater, a high indoor cooling effect can be obtained. In addition, since the exhaust duct end of the exhaust duct is spaced apart from the building wall, the exhaust air flows in the direction of the air outlet and in the direction of the outside air due to the wind pressure, and the static pressure action prevents the entry of dust, insects, etc. . Also, foreign matter from the air duct opening does not occur due to high wind pressure.
(3) Since the bellows-type shutter is provided between the exhaust duct and the building interior, the amount of inflow cold air can be adjusted freely and easily, and only the necessary amount of cold air can be sent efficiently. Moreover, since the ratio of the amount of cold air can be variably adjusted, the amount of cold air supplied can be arbitrarily adjusted according to the required cooling capacity that changes depending on the outside air temperature, indoor conditions, and the like.

Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.
FIG. 1 is a side view showing an embodiment of the present invention, FIG. 2 is an enlarged view of a main part of an exhaust duct and an intake port, FIG. 3 is a front view, and FIG. It is AA sectional view taken on the line of a).

  As shown in FIG. 1, the cold air supply device according to the present invention uses an eco water heater 1 installed as a hot water supply facility for a building, and is configured by attaching an exhaust duct 3 to the eco water heater 1. In order to control the cooling temperature by guiding the exhaust air from the intake window 5 established on the wall 7 of the building to the indoor, and adjusting the amount of cold air flowing into the room by the air volume adjusting shutter 6 provided in the intake window 5. Has been.

  Specifically, the opening and closing amount of the intake window 5 can be freely adjusted by dividing the intake window 5 with an accordion (bellows) type shutter 6 and moving it to the left and right with a handle 6a as shown in FIG. Like that. In this way, since the cool air is directly introduced from the eco water heater 1, a high indoor cooling effect can be obtained. Further, by providing the exhaust duct 3 with the exhaust port end spaced apart from the building wall with a gap of an arbitrary distance d (about 50 mm), the exhaust cool air flows in the direction of the air outlet and the direction of the air outlet through the air outlet, The static pressure action prevents dust and insects from entering. Also, foreign matter from the opening of the exhaust duct 3 does not occur due to high wind pressure.

  The buildings where the eco water heater 1 is installed include ordinary houses, commercial facilities, offices, schools, factories, etc., but the cold air supply device of the present invention is preferably installed in a hot spring facility or a spa facility of the additional cooking system. It is. Moreover, you may install in the bedroom of a general household. The eco water heater 1 heats and stores water with energy obtained by exchanging heat with the atmosphere using carbon dioxide as a refrigerant, and is used as a heating device that utilizes a heat radiation action in a condenser including a compressor. That is, the hot water obtained by heating the water by the refrigerant heated to a high temperature by compressing the refrigerant that has absorbed heat from the atmosphere in the heat exchanger 8 is stored in the hot water storage tank 2.

  The eco water heater 1 has a high energy-saving effect, and it can supply power at a low cost of about 1/3 from 11:00 pm to 7:00 am when power demand decreases by contracting with an electric power company. Running costs can be greatly reduced by using the late-night electricity rate system. In addition, because no fire is used, there is no danger of poisoning due to fire or incomplete combustion, and air pollution caused by combustion gases such as carbon dioxide emissions, and condensation due to water vapor generated during combustion can be prevented, improving the indoor environment, etc. There are many advantages, and further spread is expected in the future.

  In addition, the gist of the present invention is to provide a cold air supply device that can help cool the indoor building facility by reusing the cold air exhausted from the eco water heater, as long as it has the main components of the present invention, Needless to say, various modifications can be made without being limited to the above-described embodiments. For example, in this embodiment, the air volume adjusting shutter is an accordion type (bellows) type, but may be a slit type or the like.

It is a side view which makes one embodiment of the present invention. It is a principal part enlarged view of an exhaust duct and an inlet port. (A) which shows an air volume adjustment shutter is a front view, (b) is the sectional view on the AA line of Fig. (A).
