本発明は空冷ヒートポンプ式空気１１７Ｊ和機の除霜運
転時の冷風吹出防止に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to prevention of blowing out of cold air during defrosting operation of an air-cooled heat pump type air 117J machine.

As shown in the figure, the indoor unit has a blower 2 installed in an indoor cabinet 1, and is equipped with an air inlet 3 and an air outlet 4 of the blower 2. It is disposed in a ventilation path between the blower 2 and the air suction port 3, and is connected to a check valve 11 and a cabin retube 16. In addition, the outdoor unit has a blower 6, a compressor 7, a four-way switching valve 8, and a heating valve inside the outdoor cabinet 5.
Install the pillar tube 13 and check valve 15,
The indoor and outdoor units are connected by a gas side refrigerant pipe 9 and a liquid side refrigerant pipe 12.

冷却することになる。During heating operation, the indoor heat exchanger 1° acts as a condenser, exchanging heat with the air sucked in from the air suction port 3, and radiating heat to heat the room. When n builds up in the outdoor heat exchanger 14 due to continued heating operation, 1' (= periodically 4-way l; Outside heat exchanger 1
4 acts as a condenser, and 1 unit is used for removing l'a. At this time, the indoor heat exchanger temporarily acts as an evaporator to cool the intake air.

阻害するという欠点を有していた。As described above, conventional air conditioners blow cold air toward the indoor side during non-employment operation, causing occupants in the room to feel a cold draft, which significantly impairs heating comfort. One way to improve the above is to stop the operation of the blower or to operate the blower with a slight breeze, but in the former case, the heat absorption from the indoor heat exchanger 10 is significantly inhibited, and as a result, the outdoor heat Heat dissipation in the exchanger 14 is insufficient, resulting in damage such as a significant delay in defrosting time and poor removal. In the latter case, the reach of the cold air is shortened by the breeze, but the cold air falls in front of and below the air conditioner, so the air volume is lower than the breeze pressure. This combination of factors, such as a decrease in the temperature of the cold air, a decrease in the heat absorption effect of the indoor heat exchanger 10 due to the breeze, and a longer defrosting time, causes a large amount of cold air to stagnate in front of and below the air conditioner. This has the disadvantage that it creates a large area and impedes the comfort of the occupants.
本発明は上記の点に鑑みてなされたもので、除Ｎ運転時

空気調和機を提供することを目的とするものである。The present invention has been made in view of the above points, and an object of the present invention is to provide an improved air-cooled heat pump type air conditioner that prevents cold air from blowing out during N removal operation.

It is characterized by the following.

In the figure, the same parts as in FIG. 1 are denoted by the same reference numerals, and the explanation thereof will be omitted. 17 is a heat storage device. The heat storage device is arranged on the leeward side of the heater 3-10, and is provided separately from the indoor heat exchanger 10. However, the heat radiation/absorption fins 20 of the heat storage device 17 can also be used as the indoor heat exchanger 10 and the fins. 21 is a temperature regulator. The temperature regulator 21 instructs the indoor blower to operate with a gentle breeze or to stop when the heat storage device performs heat absorption at the start of the heating operation or when the heating operation is stopped. Reference numeral 18 denotes pipes made of metal or synthetic resin, which contain low melting alloys, organic or inorganic solvents, oils and fats, other elements or It is filled with a heat storage agent 19 such as a compound. 22 is an electric heater. The electric heater 22 is preferably a small-sized cord heater, and is linked to the temperature regulator 21. This electric heater 22 is used to prevent the amount of heat accumulated while the air conditioner is out of operation from being released. The electric heater 22 can also be attached to the side wall of the tubing 18 or to a part of the wine 2 [1].

改善することができる。4-19 is cooled and when it solidifies or condenses, it radiates heat and heats the air, making it possible to eliminate cold air blowing. Further, when the indoor temperature is sensed and the heat pump heating operation is temporarily stopped, the blower 2 is stopped or operated with a slight breeze, and the wind speed is lowered to lower the actual temperature and reduce discomfort. Also, mainly when the indoor temperature is low, such as at 1 o'clock when heating operation starts,
Moreover, when the heat storage device 17 absorbs heat, the temperature controller 21
Therefore, until the temperature of the blown air or the temperature of the heat storage device 17 or the indoor ventilation exchanger 10 rises to an appropriate concentration, perform light air operation control or stop the blower to prevent problems caused by blowing cold air when heating is started. I try not to let myself feel pleasure. Furthermore, by activating the electric heater 22 for peace of mind, the preheating effect can be enhanced and the blowing of cold air at the time of heating start-up can be improved.
