Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a whole-house heating system. Background Technology

[0002] Currently, heating equipment is classified into air source heat pumps and gas boilers according to the type of heat source. Existing commercial gas boilers generally use high power and directly connect multiple manifolds through coupling tanks for water distribution. They are equipped with only one high-power water pump, which is installed at the return end of the coupling tank.

[0003] However, high-power gas boilers are expensive, and heating comfort is reduced after a malfunction; the hot water function leads to frequent start-stop cycles when heating a large area; and the individual water pumps are powerful, noisy, and expensive, requiring larger pipe diameters for home installations, making installation difficult. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of existing high-power gas-fired heating and hot water boilers with high-power water pumps, which result in low heating comfort, and to provide a whole-house heating system.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides a whole-house heating system, which includes: multiple gas boilers connected in parallel, a buffer water tank, and multiple circulating water pumps connected in parallel.

[0007] The buffer water tank is provided with a first circulation inlet, a first circulation outlet, a second circulation inlet, and a second circulation outlet;

[0008] The first circulating water inlet is connected to the water outlet of each gas-fired boiler through a first circulating water inlet pipe, and the first circulating water outlet is connected to the water inlet of each gas-fired boiler through a first circulating water outlet pipe.

[0009] The second circulation inlet is connected to the outlet of each of the circulating water pumps via a second circulation inlet pipe, and the second circulation outlet is connected to the inlet of each group of water collectors via a second circulation outlet pipe.

[0010] Preferably, the whole-house heating system further includes multiple expansion tanks connected in parallel, with each of the circulating water pumps and the buffer tank having an expansion tank between them.

[0011] Preferably, the first circulating water inlet and the first circulating water outlet are located on the right end face of the buffer water tank, and the second circulating water inlet and the second circulating water outlet are located on the left end face of the buffer water tank.

[0012] Preferably, the volume of the buffer tank is 180L-200L.

[0013] Preferably, the buffer tank is further provided with a water inlet, a water outlet, and an automatic air vent valve located at a first preset position.

[0014] Preferably, the circulating water pump is equipped with a temperature controller;

[0015] The temperature controller is used to control the circulating water pump to stop running when the circulating water temperature of the second circulating water inlet pipe reaches the first set temperature, and to control the circulating water pump to start running when the circulating water temperature of the second circulating water inlet pipe reaches the second set temperature.

[0016] Preferably, the circulating water pump is equipped with shut-off valves at both ends.

[0017] Preferably, each water collector group includes a first water collector and a second water collector.

[0018] The positive and progressive effects of this utility model are as follows: It provides a whole-house heating system that uses multiple small single-gas boilers connected in parallel. Even if one boiler fails, the others can still provide heating normally, improving heating comfort; the large-volume buffer tank provides better hydraulic balance distribution, preventing uneven water flow caused by pressure differences; the multi-pump return system reduces the power of individual pumps, thereby reducing costs and noise; and the use of small-power single-gas boilers also reduces the diameter of pipes laid in home decoration, making installation easier.

[0020] Figure 2 This is a schematic diagram illustrating the working principle of the whole-house heating system according to Embodiment 1 of this utility model. Detailed Implementation

[0021] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0022] Example 1

[0023] This embodiment provides a whole-house heating system 100, which includes: multiple gas boilers 110 connected in parallel, a buffer water tank 120, and multiple circulating water pumps 130 connected in parallel.

[0024] The buffer water tank 120 is provided with a first circulation inlet 121, a first circulation outlet 122, a second circulation inlet 123, and a second circulation outlet 124;

[0025] The first circulation inlet 121 is connected to the outlet of each gas-fired boiler 110 through the first circulation inlet pipe 151, and the first circulation outlet 122 is connected to the inlet of each gas-fired boiler 110 through the first circulation outlet pipe 152.

[0026] The second circulation inlet 123 is connected to the outlet of each circulation pump 130 through the second circulation inlet pipe 153, and the second circulation outlet 124 is connected to the inlet of each group water collector 140 through the second circulation outlet pipe 154.

[0027] The following text, combined with Figure 1 Further explanation is provided regarding the aforementioned whole-house heating system 100.

[0028] In this embodiment, multiple gas-fired boilers 110 connected in parallel are used to replace traditional high-power heating and hot water boilers. This ensures output power while reducing the impact of malfunctions, solving the problem of heating comfort, and ensuring that heating effect is not interrupted even if a single machine fails. Multiple individual boilers are connected in parallel to a buffer water tank 120, and each boiler has its own independent supply and return water interface, so they do not interfere with each other.

[0029] In one embodiment, the whole-house heating system also includes multiple expansion tanks 160 connected in parallel, with an expansion tank 160 located between each circulating water pump 130 and buffer tank 120.

[0030] In one embodiment, the volume of the buffer tank 120 is 180L-200L.

[0031] In this embodiment, the expansion tank 160 absorbs water pressure, and the 200L buffer tank 120 serves as an intermediate heat exchange transfer point. This solves the problem of large circulating water area, limited space for pressure release after thermal expansion, and uneven water distribution among multiple manifolds, thus achieving a comfortable heating effect throughout the house.

[0032] In one embodiment, the first circulation inlet 121 and the first circulation outlet 122 are located on the right end face of the buffer tank 120, and the second circulation inlet 123 and the second circulation outlet 124 are located on the left end face of the buffer tank 120.

[0033] In one embodiment, the buffer tank 120 is further provided with a water inlet, a water outlet, and an automatic air vent valve located at a first preset position.

[0034] In one embodiment, each water collector 140 includes a first water collector 141 and a second water collector 142.

[0035] In this embodiment, the positions of the first circulation inlet 121, the first circulation outlet 122, the second circulation inlet 123, and the second circulation outlet 124 can be set according to the actual situation. The buffer tank 120 can also be provided with two or more circulation inlets and circulation outlets, which are connected to the heating boiler. The inlet and outlet of the buffer tank 120 connected to the manifold can be set according to the number of return water lines.

[0036] In one embodiment, the circulating water pump 130 is equipped with a temperature controller;

[0037] The temperature controller is used to control the circulating water pump 130 to stop running when the circulating water temperature of the second circulating water inlet pipe 153 reaches the first set temperature, and to control the circulating water pump 130 to start running when the circulating water temperature of the second circulating water inlet pipe 153 reaches the second set temperature.

[0038] In one embodiment, the circulating water pump 130 is provided with shut-off valves at both ends.

[0039] In this embodiment, multiple circulating water pumps 130 are used for water return, solving the problems of large pipe diameter and high return water noise, achieving quiet operation and convenient installation. A temperature controller is installed on each circulating water pump 130. When the circulating water temperature reaches the first set temperature, the circulating water pump 130 stops; when the circulating water temperature is lower than the second set temperature, the circulating water pump 130 starts. A thermostat is installed in the room to control the on / off switch of the thermal actuator of the manifold 140. Shut-off valves are installed at both ends of the circulating water pump 130 to cut off the water flow at both ends of the circulating water pump 130, facilitating replacement and maintenance of the circulating water pump 130.

[0040] In one embodiment, such as Figure 2 As shown, the outlets of three gas-fired heating and hot water boilers (G06) are connected to the circulation inlet of a 200L buffer insulated water tank via a first DN20 pipe, and the inlets of the three gas-fired heating and hot water boilers (G06) are connected to the circulation outlet of the 200L buffer insulated water tank via a second DN20 pipe. The outlets of three three-phase circulating pumps are connected to another circulation inlet of the 200L buffer insulated water tank via a first DN25 pipe, and the inlets of three-unit manifolds are connected to another circulation outlet of the 200L buffer insulated water tank via a second DN25 pipe. By using multiple parallel single-heating boilers and multiple water pumps for return water, the system ensures output power while reducing the impact of malfunctions and improving heating comfort.

[0041] This embodiment provides a whole-house heating system that uses multiple small single-gas boilers connected in parallel. Even if one boiler fails, the others can still provide heating normally, improving heating comfort. A large-volume buffer tank provides better hydraulic balance distribution, preventing uneven water flow caused by pressure differences. Multiple water pumps reduce the power of individual pumps, thus reducing costs and noise. The use of low-power single-gas boilers reduces the diameter of pipes laid in home renovations, facilitating installation.

[0042] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
