換器へ送り。As is clear from the above description, according to the present invention, electric power is supplied by an engine generator, so that the energy cost x is cheaper than in the case of commercial electric power. Furthermore, since the waste heat of the engine generator is recovered, the efficiency of the engine generator can be increased to 92-98%. In addition, hot water is produced by recovering waste heat from the engine generator, and this hot water is used as a heat source for all cooling operations of the absorption chiller, so the energy cost for cooling is also reduced. In the summer, temperatures rise and the power consumption of refrigerator/freezer showcases also increases, but at this time the engine generator also operates at full capacity, the amount of hot water increases, and the refrigerating capacity of the absorption chiller also increases. effective. Furthermore, a built-in type refrigerated showcase can be used in which the refrigerant compressor and condenser of the cooling unit are installed at the bottom of the showcase. Meanwhile, in winter, hot water is recovered from the engine generator's waste heat and sent to the air conditioning heat exchanger.
