Kind Code:
B2
Abstract:
[Problem] To improve efficiency as the whole of an air conditioning/hot-water supply system. [Solving Means] The present invention includes hot-water supply assisting means (80) for using heat occurred in heating operation in hot-water supply operation. A control device (1a) includes: means (S10) that estimates a current air conditioning load; means (S11) that estimates a current air conditioning power consumption; means (S12) that estimates a current hot-water supply load; means (S13) that estimates a current hot-water supply power consumption; means (S16) that tentatively determines the estimated air conditioning load; means (S18) that calculates a new air conditioning load by adding a predetermined value to the tentatively determined air conditioning load; means (S18) that calculates an air conditioning power consumption based on the new air conditioning load; means (S19) that calculates a hot-water supply load based on the new air conditioning load; means (S20) that calculates a hot-water supply power consumption based on the new hot-water supply load; means (S22) that compares a total power consumption; and assist control means that controls action of the hot-water supply assisting means to approximate the new air conditioning load when the total power consumption is smaller (Yes at S22).
