Heating the water heater (冷暖 房 給 湯 裝置)

摘要

A heat pump style chiller unit is operated in a heating cycle or a cooling cycle. A water circuit is connected to the contact heat exchanger of the chiller unit. A fan coil for air conditioning is connected in parallel in the heat exchanger for water tank. A change piece operates one of the heat exchanger for the tank and the fan coil unit. A water tank circuit delivers the water from the tank through a pump. The first program timer sets the storing time range of the tank, which is stored by operating the heat exchanger, and the air conditioning time range. The second program timer sets the tank operating time range by driving the pump.
