Background

Currently, the main stream of heating equipment is divided into two main categories according to the type of heat source, namely an air source heat pump and a gas heating furnace (also called a wall-mounted furnace). The air source heat pump and the gas heating furnace have advantages and disadvantages respectively. For example, an air source heat pump is a very energy-saving and environment-friendly product, but the heating performance of the air source heat pump is greatly attenuated along with the reduction of the outdoor temperature, and the reliability is low; the gas heating stove uses clean natural gas, can stably and permanently produce heat, and has lower initial investment. Obviously, the two heat source devices have a certain complementarity. Therefore, in practical application, some manufacturers start to attempt to integrate an air source heat pump and a gas heating furnace into a system, and selectively adopt a single heat source or double heat sources to heat according to conditions of environmental temperature and heat load, so that the advantages of the two heat sources are fully exerted.

Currently, most of the structures of integrated dual-heat source heating furnaces appearing on the market are: the water tank with coil is used as an intermediate medium, and the whole set of equipment formed by the air source heat pump and peripheral devices thereof and the whole set of equipment formed by the gas heating stove and peripheral devices thereof are connected in parallel to the same system, and the defect is that: the integrated mode is that only the mutually independent air source heat pump and the gas heating furnace are connected through the water tanks, the whole equipment which is mutually independent is arranged between the heat sources, the large installation area is occupied, the linkage control efficiency is low, a plurality of water tanks are needed as intermediate media for heat energy exchange, the independent circulating power components are needed for the heat sources, and the overall cost and the running cost of the scheme are high.

Example 1

As shown in fig. 1 and 2, an integrated dual heat source heating apparatus 100 according to a first embodiment of the present utility model is shown.

As shown in fig. 1, the integrated dual heat source heating apparatus 100 includes: an indoor unit 10 and an outdoor unit 20 connected to the indoor unit 10. The indoor unit 10 is used for integrating other main devices except the air source heat pump 21, and is installed in a room of an applicable place in a modularized unit during installation, and meanwhile, the heating waterways of the integrated dual-heat source heating device 100 are integrated in the indoor unit 10, so that the probability of freezing the heating waterways in winter can be reduced. The outdoor unit 20 mainly includes an air source heat pump 21 and is placed outdoors to extract heat from air of the external environment.

Hereinafter, the integrated dual heat source heating apparatus 100 described above will be further described with reference to fig. 1 and 2.

As shown in fig. 1, the indoor unit 10 includes: the buffer water tank 11, the water pump 12, the gas-water heat exchanger 13 and the gas heating furnace 14 are connected in sequence. The buffer tank 11 is provided with a return water interface 111, which return water interface 111 is intended to be connected to the outlet end of the water separator 200 of the heating system. A water flow sensor 15 and a backwater temperature sensor 16 are arranged between the water pump 12 and the air-water heat exchanger 13. A heat pump water outlet temperature sensor 17 is arranged between the gas-water heat exchanger 13 and the gas heating furnace 14. The gas heating furnace 14 is provided with a water outlet 18 with a heating furnace water outlet temperature sensor 181 and a gas outlet 19 with a gas valve 191. The water outlet port 18 is used to connect the inlet end of the water separator-collector 200.

As shown in fig. 1, in the present embodiment, a drain valve 112 is provided at the bottom of the buffer tank 11. The drain valve 112 can drain water and drain sewage to the buffer water tank 11, so that operators can clean and maintain the buffer water tank 11 regularly, and effective operation of a heating circulation waterway is ensured.

As shown in fig. 1, in the present embodiment, an exhaust valve 113 is provided at the top of the buffer tank 11. The exhaust valve 113 is used for exhausting the gas stored in the buffer water tank 11, so that the pressure relief and the cleaning maintenance are facilitated.

Based on safety considerations, as shown in fig. 1, in the present embodiment, the indoor unit 10 may further include: an expansion tank 110 connected between the buffer tank 11 and the water pump 12. When the heating system works, heating water is heated and expanded to cause the pressure of the heating system to rise, the expansion tank 110 plays a role in absorbing expansion amount and stabilizing the pressure of the heating system, and the operation safety of the indoor unit 10 is improved.

As shown in fig. 1, the outdoor unit 20 includes: an air source heat pump 21 connected to the air-water heat exchanger 13. The air source heat pump 21 is connected with the air-water heat exchanger 13 through a refrigerant pipeline. Here, as shown in fig. 2, the line in the direction of the arrow toward the air-water heat exchanger 13 is a refrigerant gas pipe, and the line in the direction of the arrow toward the air source heat pump 21 is a refrigerant liquid pipe.

The working principle is briefly described:

As shown in fig. 2 (in which the arrow indicates the flow direction of the liquid or the refrigerant, in particular, the top position of the gas heating furnace 14, the arrow vertically upward indicates the direction of exhaust of the flue gas, and the arrow horizontally indicates the direction of intake of the air), the air source heat pump 21, the gas heating furnace 14, and the respective peripheral devices are recombined to obtain a highly integrated dual-heat-source heating system composed of the indoor unit 10 and the outdoor unit 20. Wherein the air source heat pump 21 is integrated to the outdoor unit 20 and transfers heat energy to a waterway of the indoor unit 10 by exchanging heat with the air-water heat exchanger 13 in the indoor unit 10. The indoor unit 10 and the water diversion/collection device 200 and the floor heating coil 300 of the heating system constitute a circulation water path for heating (after the heating water flowing out of the indoor unit 10 enters the water diversion/collection device 200, the heating water flows into the floor heating coil 300 to perform heat radiation and heating, and the cooled heating water flows back from the water diversion/collection device 200 to the indoor unit 10). The liquid returned by the heating system flows back to the buffer water tank 11 and is pumped to the air-water heat exchanger 13 through the water pump 12 to realize primary heat exchange and temperature rise with the air source heat pump 21. Then, the liquid flows into the gas heating furnace 14 to perform the secondary heat exchange and the temperature rise, and flows back to the heating system again to perform heating. In operation, the water flow sensor 15, the backwater temperature sensor 16, the heat pump water outlet temperature sensor 17 and the heating stove water outlet sensor 181 respectively collect and feed back the liquid temperature of the waterway, and then the air source heat pump 21 and the gas heating stove 14 are operated alternatively or simultaneously, so that the purpose of efficient double heat source heating can be achieved.

When only the air source heat pump 21 is needed for heating, heat exchange is performed by the air-water heat exchanger 13 to heat heating water, and at this time, the gas heating furnace 14 does not work, and the heated heating water flows through the gas heating furnace 14 and then enters the water collecting and distributing device 200.

When only the gas heating furnace 14 is needed for heating, the air source heat pump 21 does not work, and the return heating water does not exchange heat through the gas-water heat exchanger 13, so that the water temperature is kept unchanged. Then, the heating water flows into the heat exchanger of the gas heating furnace 14, exchanges heat with the hot water heated by the burner, and increases the temperature, and the heated heating water flows into the water separator 200.

When the dual heat source heating is required, the air source heat pump 21 and the gas heating furnace 14 start to operate.

In the integrated dual-heat-source heating apparatus 100, the indoor unit 10 may include a control board or a console, or may be a control system connected to an upper layer through a data line or a wireless network.

The integrated dual-heat-source heating device 100 is capable of re-integrating the air source heat pump 21, the gas heating furnace 14 and respective peripheral devices to obtain a highly integrated dual-heat-source heating system consisting of the indoor unit 10 and the outdoor unit 20, reducing the occupation of the installation area, and having high linkage control efficiency, avoiding the heat exchange requirement of a plurality of water tanks, integrating the circulating power components of each heat source, and reducing the overall cost and the running cost of the scheme.

Example two

As shown in fig. 3 and 4, an integrated dual heat source heating apparatus 100 according to a second embodiment of the present utility model is shown.

The difference between this embodiment and the first embodiment is that: in this embodiment, based on the monitoring requirement for the operation state of the device, the safety of the operation of the device is improved, and the following improvement is made.

For example, as shown in fig. 3, in the present embodiment, a pressure gauge 1101 is provided between the water pump 12 and the buffer tank 11. The pressure gauge 1101 is used for monitoring the water pressure of the waterway of the indoor unit 10, so that an operator can intuitively know the current water pressure or can feed back to an upper control system.

As another example, as shown in fig. 3, in the present embodiment, a safety relief valve 1102 is provided between the water pump 12 and the buffer tank 11. The safety relief valve 1102 is used for automatically performing a relief process when the water pressure in the water path of the indoor unit 10 reaches a dangerous threshold, thereby improving the safety of the operation of the device.

In addition, in theory, the amount of liquid in the water path of the heating system is kept constant. However, in the actual operation, the water path of the heating system inevitably leaks with the accumulation of the operating time. Therefore, the water supplementing channel can be set in a targeted manner.

For example, as shown in fig. 3, in the present embodiment, a water replenishment port 1103 with a water replenishment valve 11031 is provided between the water pump 12 and the buffer tank 11, and the water replenishment port 1103 is used for connecting to a running water network. The water supply port 1103 can supply water to the water channel of the indoor unit 10 by using the water supply network, and the normal operation of the heating system is maintained. It should be noted that the water supply port 1103 may be connected to other types of water sources, such as a water storage tank, and is not limited to a water supply network.

It is to be understood that the position of the water supply port 1103 is not limited to the position between the water pump 12 and the buffer tank 11, and may be provided on the buffer tank 11 or on the water return port 111. For example, the buffer tank 11 may be provided with a refill port 1103 with a refill valve 11031. The water supplementing interface 1103 is used for connecting a tap water network. The water supply port 1103 can supply water to the water channel of the indoor unit 10 by using the water supply network, and the normal operation of the heating system is maintained.

Other structures of the present embodiment are the same as those of the first embodiment, and the advantageous effects of the first embodiment can be achieved. Meanwhile, the working principle diagram of the present embodiment is shown in fig. 4, which is the same as the first embodiment (adding water supply to the tap water network), so that the description thereof is omitted.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples only represent preferred embodiments of the present utility model, which are described in more detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
