Benefits of technology

[0018]According to the fourth invention, in a composite heat source machine which performs a hot-water supply operation and a room heating operation, the carbon dioxide emission reduction degree that results from changing to the current heat source machine in the case of performing the hot-water supply operation and the carbon dioxide emission reduction degree that results from changing to the current heat source machine in the case of performing the room heating operation can be separately recognized by the user.

Problems solved by technology

However, the above-mentioned conventional heat source machine merely displays the information of the carbon dioxide emission reduction amount in comparison with the uniform reference heat source machine, and so cannot meet the user's interest.

Embodiment Construction

[0024]The following describes an embodiment of the present invention with reference to FIGS. 1 to 5.

[0025]In FIG. 1, a gas heat source machine 1 of this embodiment (corresponding to a heat source machine according to the present invention) is a high-efficiency, latent heat recovery-type heat source machine having a hot-water supply function and a room heating function, and uses natural gas as fuel gas.

[0026]The gas heat source machine 1 includes: a hot-water supply main heat exchanger 100a (mainly absorbing sensible heat from exhaust gas of a hot-water supply burner 101) and a hot-water supply auxiliary heat exchanger 100b (mainly absorbing latent heat from the exhaust gas of the hot-water supply burner 101) that are provided at some intermediate point of a hot-water supply pipe 105 and heat water to be heated flowing through the hot-water supply pipe 105; and a room heating main heat exchanger 110a (mainly absorbing sensible heat from exhaust gas of a room heating burner 111) and a...

Abstract

A heat source machine includes: a first emission amount calculation unit 12 which calculates a first carbon dioxide emission amount that is an amount of carbon dioxide emitted to obtain an energy source consumed in a hot-water supply operation; a second emission amount calculation unit 13 which calculates a second carbon dioxide emission amount that is an amount of carbon dioxide emitted to obtain an energy source consumed in a reference heat source machine on an assumption that the reference heat source machine performs the same operation as the hot-water supply operation; and a carbon dioxide emission reduction degree display unit 14 which displays a carbon dioxide emission reduction degree that results from changing to the current heat source machine, according to a difference between the first carbon dioxide emission amount and the second carbon dioxide emission amount.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a heat source machine having a function of displaying a carbon dioxide emission reduction degree.[0003]2. Description of the Related Art[0004]As a conventional heat source machine, there is proposed a latent heat recovery-type hot-water supply device which calculates a carbon dioxide emission reduction amount with respect to a reference hot-water supply device (a standard hot-water supply device), and displays information of the carbon dioxide emission reduction amount on a display screen of a remote control (for example, see Japanese Patent Application Laid-Open No. 2004-20150).[0005]The hot-water supply device described in the above-mentioned patent document allows a user to recognize to what degree carbon dioxide emissions are reduced with respect to the reference hot-water supply device as a result of replacing with the latent heat recovery-type hot-water supply device.[0006]In the c...
