Abstract

PROBLEM TO BE SOLVED: To boil water by effectively utilizing waste heat of cooling operation that is discharged to outside and discarded in a conventional air conditioner.SOLUTION: A system for boiling water by utilizing waste heat is constituted by additionally connecting a heat exchanger for water heating right before a heat exchanger for air cooling radiation in series in a refrigerant gas circulation path of an outdoor machine 2, and by boiling water with heat collected in an indoor machine 1 of a heat pump air conditioner before discharging the heat to store the hot water in a tank.

Description

ヒートポンプエアコンの冷房運転時、室内機で回収した熱を大気中に放熱する前に排熱を有効利用して湯を沸かす為の技術である。This technology is used to boil hot water by effectively using exhaust heat before the heat recovered by the indoor unit is released into the atmosphere during the cooling operation of the heat pump air conditioner.

冷房運転時に、室内機１で回収した熱は、屋外機２の熱交換機から、無駄に排熱していた、その熱を利用して湯を沸かすようにする。During the cooling operation, the heat recovered by the indoor unit 1 is boiled from the heat exchanger of the outdoor unit 2, so that hot water is boiled using the heat.

冷房運転時、エアコン屋外機２の冷媒ガス循環経路で放熱用熱交換器の直前に水冷用の熱交換機４を直列に追加して、冷却熱交換と同時に湯を沸かしてタンク３に貯湯する事で温水器として利用する事ができる。During cooling operation, a water-cooling heat exchanger 4 is added in series immediately before the heat-dissipating heat exchanger in the refrigerant gas circulation path of the air conditioner outdoor unit 2, and hot water is boiled simultaneously with cooling heat exchange and stored in the tank 3 It can be used as a water heater.

従来のエアコンは冷房中、室内で回収した熱は大気中へ無駄に放出していたが、その熱を利用して湯を沸かし、給湯器として利用が出来る。In conventional air conditioners, the heat recovered indoors was wasted to the atmosphere during cooling, but the heat can be used to boil hot water and be used as a water heater.

従来、大気中に空冷放熱していた熱を利用して湯を沸かす工程は、水冷とする冷却と同じで、空冷に対して、冷房能率は向上する為、節電にもなる。Conventionally, the process of boiling hot water using heat that has been dissipated in the atmosphere by air cooling is the same as cooling by water cooling, and the cooling efficiency is improved with respect to air cooling, thus saving power.

エアコンの屋外機から大気中に放出する熱は、ヒートアイランド現象を発生させるが、その熱で湯を沸かす事は、捨てる熱を水中に保存する為、直接に大気を加熱する割合を減らし、環境に対する負荷も低減出来る。The heat released from the outdoor unit of the air conditioner to the atmosphere causes a heat island phenomenon, but boiling the hot water with that heat saves the discarded heat in the water, so the rate of heating the atmosphere directly is reduced, and The load can also be reduced.
