Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to an indoor temperature compensation control device. Background Art

[0002] Heating is the earliest building environment control technology developed by humans. Since humans learned to use fire, they have invented heating methods such as kangs, stoves, fire walls, and fire floors to resist the threat of cold to survival. These are the earliest heating equipment and systems. Now it has become a social service to solve the basic living needs of residents in northern my country for heating in winter.

[0003] The penetration rate of heating systems is gradually increasing. For building heating, in order to avoid the water temperature not meeting the heating standards when heating the high floors of the building, heating companies will often heat the water to a higher temperature, or add heating equipment between floors to increase the water temperature. The former will cause higher water temperature for the lower floors of the building, causing certain discomfort to the residents on the lower floors, and the latter will have a higher construction cost.

[0004] Therefore, we propose an indoor temperature compensation control device to solve the above problems. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] When the hot water is supplied to each household and the heat exchange is completed for heating, the cooled water flows back to the water tank through the return pipe. By adding a return main pipe and a return branch pipe at the tail end of the return pipe, the return branch pipe corresponds to each household pipe one by one, and the returned cooling water flows into the household pipe from the return branch pipe to mix with the hot water. The water temperature sensor feeds back the mixed water temperature to the main controller, and the main controller controls the opening and closing size of the first electric control valve to control the flow rate of the cooling water, so as to ensure that the cooling water and hot water are mixed to the appropriate temperature before heating each household, so as to improve the residents' user experience.

[0018] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figure 1As shown, the utility model provides an indoor temperature compensation control device, including a water supply pipe 1, a return pipe 2, a household pipe 3, a return main pipe 4, a return branch pipe 5, a first electrically controlled valve 6, a second electrically controlled valve 7, a water temperature sensor 8, a main controller 9 and a booster pump 10. The water supply pipe 1 is used to provide hot water. The return pipe 2 is arranged at the end of the water supply pipe 1 and is used to recover cooling water after heat exchange heating. A plurality of household pipes 3 are arranged on the water supply pipe 1. Each household pipe 3 is connected to the water heating equipment of each household so that the hot water supplied by the water supply pipe 1 flows into each household. A second electrically controlled valve 7 is arranged on the return main pipe 4 to control the hot water supply of each household. The return main pipe 4 is connected to the return pipe 2. A plurality of return branch pipes 5 are arranged on the return main pipe 4. The return branch pipe The number of 5 is the same as that of the household pipe 3, and its water outlet end is connected with each household pipe 3 respectively. The first electrically-controlled valve 6 is installed on the return branch pipe 5, and a water temperature sensor 8 is installed on each household pipe 3. The second electrically-controlled valve 7 is located on the side of the return branch pipe 5 close to the water supply pipe 1, and the water temperature sensor 8 is located on the side of the return branch pipe 5 entering the house to ensure that the water temperature sensor 8 can detect the mixed water temperature. The first electrically-controlled valve 6, the second electrically-controlled valve 7, and the water temperature sensor 8 are all electrically connected to the main controller 9.
