Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As a kind of floor radiant heating, floor heating has gradually entered the public's field of vision. It supplies indoor heat through ground radiation and convection conduction. It has the advantages of high thermal efficiency and mature technology. It is a scientific, energy-saving and health-care heating method. Its "warm feet and cool roof" heating method is a symbol of the quality of modern life. However, the floor heating in the prior art still has shortcomings such as lack of comfort and high energy consumption.

Referring to FIGS. 1-4 , this embodiment provides a floor heating module 10 and a floor heating device 100 , which can effectively alleviate the technical problem.

Referring to FIGS. 1 and 2 , in this embodiment, the floor heating module 10 includes a first inflow channel 111 , a second inflow channel 112 , a confluence channel 131 , a first outflow channel 121 and a second outflow channel 122 . The inflow ends of the first inflow channel 111 and the second inflow channel 112 are both used for inflowing the heat medium; The inflow ends of the first outflow channel 121 and the second outflow channel 122 are both communicated with the outflow end of the confluence channel 131 , and the outflow ends of the first outflow channel 121 and the second outflow channel 122 are both used to flow out the heat medium.

In FIGS. 1 and 2 , the number of inflow channels is two, which are the first inflow channel 111 and the second inflow channel 112 respectively. The number of outflow channels is two, which are the first outflow channel 121 and the second outflow channel 122 respectively. The heat medium flows in through the two inflow runners, and then flows out through the two outflow runners after converging through the converging runners 131 . This structure can be understood as a double-in and double-out type floor heating module 10 .

By realizing the confluence through the confluence flow channel 131, the flow rate can be obviously stabilized, and then the flow of the heat medium can be made more stable through this double-in and double-out method. The difference can finally make the indoor temperature distribution more uniform and have a higher comfort. Moreover, in this way, when the flow rate of the heat medium is relatively large, the energy consumption of the pump 61 (shown in FIG. 4 ) will not be significantly increased, which can save energy and reduce costs. Therefore, the double-in and double-out floor heating module 10 can effectively improve the indoor temperature quality, reduce energy consumption, and save costs.

Generally, after the floor heating module 10 is installed in place, it will be connected to the pump 61, the heating device 62 (shown in FIG. 4 ), etc. through external pipes, so that the heat medium flows through the heating device 62 to absorb heat and fully absorb heat The latter heat medium is transported into the floor heating module 10 under the driving of the pump 61 . After the heat medium flows through the floor heating module 10 to fully dissipate heat, it enters the heating device 62 again under the drive of the pump 61 to absorb heat, and the process is reciprocating.

It can be understood that in this embodiment, the cross-sectional area of the flow channel can be increased, the resistance in the flow channel can be reduced, and the energy consumption caused by the resistance when the heat medium flows in the flow channel can be effectively reduced. At the same time, the consumption of the pump 61 can be reduced, the requirements for the lift specification of the pump 61 can be reduced, and the manufacturing cost can be saved.

Of course, in other embodiments, the number of inflow channels is not limited, and may be three, four, etc., and the number of outflow channels is also not limited, and may be three, four, etc. When the number of inflow channels is three and the number of outflow channels is three, this arrangement can be understood as three in and three out. This non-single-in and single-out method can speed up the flow of heat medium in the flow channel, reduce resistance, and make the room heat up faster.

In this embodiment, the heat medium is an inorganic phase change material.

It needs to be explained that: phase change material (PCM-Phase Change Material) refers to the material that changes the state of matter with the change of temperature and can provide latent heat. The process of changing physical properties is called a phase change process, and the phase change material will absorb or release a large amount of latent heat. Inorganic phase change materials mainly include crystalline hydrated salts, molten salts, metals or alloys, etc.

The use of inorganic phase change materials as heat medium can improve the heat exchange and energy utilization of floor heating. Specifically, in this embodiment, the inorganic phase change material adopts a crystalline hydrated salt, and is mixed with a crystal structure modifying agent and an anti-supercooling agent at the same time. The good thermal properties of inorganic phase change materials are used to increase the heat exchange efficiency and bring more heat into the room. In other embodiments, the heat medium may also be water, or inorganic phase change materials such as molten salts.

Generally, using water as a heat medium is prone to water leakage, freezing and blockage, etc., and its heat exchange performance is average. In this embodiment, the stable chemical properties and structural properties of the inorganic phase change material can effectively reduce the damage to the floor heating module 10 during the phase change. At the same time, the crystal structure changing agent and the anti-supercooling agent are added to effectively reduce the possibility of the inorganic phase change material. The phenomenon of phase separation and supercooling occurs, and the pipeline is further protected to prevent the pipeline from freezing and blocking, and the leakage of heat medium. At the same time, as a heat medium, the inorganic phase change material has better latent heat and thermal conductivity than water, which can significantly improve the indoor heat exchange effect and heat exchange.

It is worth noting that in this embodiment, the inorganic phase change material is used as a heat medium, which complements the modular floor heating. Specifically, in combination with the above-mentioned dual inflow channel + confluence channel 131 + dual outflow channel, the flow of the heat medium in the floor heating module 10 is very smooth when the inorganic phase change material is selected, and the heat medium can be It is in full contact with the inner wall of the flow channel, and the heat exchange of this material itself is very sufficient. Using the advantages of the two, the heat medium can fully exchange heat with the inner wall of the flow channel during the flow process, so that the floor heating module 10 emits heat. The heat is sufficient and uniform everywhere, avoiding the situation that the local temperature is too high or the local temperature is too low. This combination can bring a more comfortable experience to the users in the room.
