Description

  The present invention relates to a hot water supply / heating system.

In recent years, a hot water supply system equipped with a combustion heat source device using fossil fuel combustion and a heating medium that heats a heating circulation heat medium (hot water, brine, etc.) by a similar combustion heat source device and supplies it to a floor heating radiator, etc. A so-called central heating system (hot water supply heating system) in which a circulation type heating system is integrated is put into practical use.
Also, in the hot water supply system, for the purpose of energy saving due to high energy efficiency, the hot water (cold water) is heated with a heat pump device (electric heat pump) and stored in a hot water storage tank. There has been devised a hot water supply system that compensates for hot water by using the combustion heat source device as an auxiliary heat source when hot water is supplied and the hot water in the hot water storage tank is exhausted. Also in the heating system, the heating circulation heat medium is first heated with a heat pump device, and the shortage of heating is compensated with the above combustion heat source machine, or the heating circulation heat medium is continuously heated with the combustion heat source machine. By switching to heating by a heat pump device, a heating system has been devised that can improve energy efficiency compared to heating only by a combustion heat source machine.
There is a demand for a hot water supply and heating system that has high energy efficiency and can contribute to a reduction in carbon dioxide emissions in a hot water supply and heating system that combines these.

  For example, in the prior art described in Patent Document 1, a combustion heat source machine (burner or the like), a heat pump device, a hot water storage tank, a heat exchanger, and the like are connected by various pipes, and various valves and pumps are combined. A hot water supply and heating system used for hot water and floor heating has been established. In this conventional technology, when hot water supply load and heating load are generated simultaneously, hot water is used before returning it to the hot water storage tank, and hot water is supplied to the hot water storage tank for this hot water use, and this is supplied to the heat pump device. Inflow.

When comparing the energy efficiency of the combustion heat source machine and the energy efficiency of the heat pump device (electric heat pump), the energy efficiency of the heat pump device is generally higher than the energy efficiency of the combustion heat source machine.
However, if a hot water supply / heating system is configured with only a heat pump device, focusing only on energy efficiency, the capacity and temperature level required for heating may be insufficient, or depending on the conditions, the primary energy efficiency of the heat pump device may be the energy of the combustion heat source unit. It may be less than efficiency. Moreover, when operating a heat pump apparatus (electric heat pump), it is preferable to use late-night power with a low electricity bill, and it is preferable to store heat from the heat pump apparatus as hot water in a hot water storage tank. Therefore, it is preferable to provide a hot water supply and heating system that combines a hot water storage tank (hot water storage device), a heat pump device, and a combustion heat source machine.

In recent years, cogeneration systems (cogeneration devices) that can generate power using an internal combustion engine, a fuel cell, and the like and also use exhaust heat generated during power generation have become widespread. By using this combined heat and power supply device in place of the heat pump device, it is possible to use the generated electric power and to efficiently perform heating and hot water supply using exhaust heat.
In addition, since the timing that requires power generation in the combined heat and power supply device does not always coincide with the timing of hot water supply or heating, the waste heat generated in the combined heat and power supply device may be stored as hot water in the hot water storage tank. preferable. Therefore, in this case, it is preferable to provide a hot water supply and heating system that combines a hot water storage tank (hot water storage device), a combined heat and power supply device, and a combustion heat source machine.

As described above, when the hot water supply and heating system is configured by combining three devices of a hot water storage device, a heat pump device, and a combustion heat source device, or by combining three devices of a hot water storage device, a combined heat and power supply device, and a combustion heat source device. When configured, it is necessary to operate each device in conjunction with each other because the efficiency is poor if the devices are operated separately.
However, if the manufacturer of each device is different, the messages for commanding the operation of each device (commands for instructing the control state, commands indicating the operating state, etc.) are different, and interlocking operation is performed by combining devices from different manufacturers. I can not let you.
Moreover, in the prior art described in patent document 1, since the case where the message between a heating apparatus and a hot water supply apparatus differs is not assumed, when it comprises and combines the apparatus of a different manufacturer temporarily, between each apparatus. The message cannot be sent and received properly, and it seems that proper interlocking operation cannot be performed. Moreover, in the prior art described in patent document 1, since it seems that the heating apparatus and hot water supply apparatus of the same manufacturer are used, there is little room for selection of a heating apparatus and a hot water supply apparatus.

When each of these temperatures (or the temperature of the hot water storage tank surface) reaches the heat storage upper limit temperature, it is determined that the heat storage state is full, and further heating (heat storage) of hot water is stopped.
In addition, the upper limit temperature (heat storage upper limit temperature) of the hot water (or hot water storage tank surface) stored in the hot water storage tank 52 differs depending on the type of the combined use device. For example, about 45 [° C.] or about 60 [° C.] is the heat storage upper limit temperature in the heat pump device, and in the gas engine combined heat and power supply device, about 75 [° C.] is the heat storage upper limit temperature. In the solid polymer fuel cell type combined heat and power supply device, a heat storage upper limit temperature of about 60 [° C.] has been put into practical use, and in the solid oxide fuel cell type combined heat and power supply device, about 70 [ [° C.] is a heat storage upper limit temperature has been put into practical use.

● [Configuration of system control device 81 (FIG. 2) and operation]
The system control device 81 relays each other's communication among the heat pump control means 11A, the combustion control means 21 and the hot water storage control means 51, and translates each so that each can recognize each other's message.
In order to efficiently operate the heat pump device 10A, the combustion heat source device 20, and the hot water storage device 50, it is necessary to operate them in conjunction with each other rather than operating them separately. In order to perform the interlock operation, it is necessary to send and receive messages to and from each other.
If each of the heat pump device 10A, the combustion heat source device 20, and the hot water storage device 50 is a device manufactured by the same manufacturer, there is often no need to particularly translate the message. However, when selecting the heat pump device 10A, the combustion heat source unit 20, and the hot water storage device 50 of the same manufacturer, there is little room for selection, and it prevents the configuration of a more efficient hot water supply / heating system.

Similarly, when the system control device 81 receives a message addressed to the heat pump control means 11A from the hot water storage control means 51, the message translated based on the translation program P (T-> H) in the storage means 83 is sent to the heat pump control means 11A. Send.
When the system control device 81 receives a message addressed to the hot water storage control means 51 from the combustion control means 21, the system control device 81 transmits a message translated based on the translation program P (N → T) in the storage means 83 to the hot water storage control means 51. .
