Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, and more specifically, it relates to an integrated inducer and radiator. Background Art

[0002] An inducer is an air conditioning terminal device installed in each room. It is a special air supply device that can induce a certain amount of indoor air to increase the air supply volume and reduce the air supply temperature difference. It consists of a box body, nozzles, a static pressure box, a primary air interface, and / or a heat exchange coil. The primary air centrally processed by the air handling unit is first sent by the air supply fan of the air handling unit into the static pressure box of the inducer installed in the air-conditioned room, and then sprayed out from the nozzles at a high speed (20 - 30 m / s). Under the action of the jet airflow, a negative pressure is formed in the inducer, so that the indoor return air can be induced in, and then mixed with the primary air to form the air supply of the air-conditioned room. Or when the indoor return air passes through the heat exchange coil, it is heated or cooled, and then mixed with the primary air to form the air supply of the air-conditioned room. For an inducer without a coil, all the indoor air conditioning cooling load or heating load is borne by the primary air centrally processed by the air handling unit. For an inducer with a coil, a part of the indoor heating and cooling load is borne by the primary air centrally processed by the air handling unit, and the other part is borne by the indoor return air heated or cooled by the heat exchange coil; the advantages of the inducer are: simple installation and no occupation of floor height; the disadvantages of the inducer are: when the air volume of the primary air after centralized processing decreases, or when the primary air after centralized processing is not cooled or heated, the cooling or heating effect of the inducer is poor; when the primary air is closed, the inducer cannot supply cooling or heating.

[0003] The radiator heats the room mainly by natural convection and supplemented by radiation. Its advantages are simple installation, no occupation of floor height, no noise, and relatively fast heating; its disadvantages are single function, only capable of heating, not cooling, and requires a high hot water temperature during heating. The hot water supply and return temperatures generally use 80 - 60 °C, and the heat source needs to be provided by a gas boiler, a coal-fired boiler, or a kerosene boiler.

[0004] The low-temperature hot water floor radiant heating system heats the room mainly by radiation and supplemented by natural convection. Its advantages are uniform heat dissipation, the floor temperature is higher than the indoor temperature, high comfort, and low required hot water temperature. Generally, the hot water supply and return temperatures generally use 45 - 40 °C, and a heat pump unit can be used for heating; its disadvantages are single function, only capable of heating, not cooling, the floor installation requires an installation space of 50 - millimeter height, is not easy to maintain, and has a short service life.

[0005] With the improvement of the index requirements of building energy conservation codes, the development of building energy conservation technologies, and the improvement of the performance of building envelopes, the air conditioning and heating loads have been greatly reduced, making it possible to use hot water for heating at a lower temperature.

[0006] Therefore, the development of a multi-functional air conditioner product that can utilize the medium-temperature hot water heat source provided by a heat pump unit at 40-50°C for heating is of great significance for energy conservation and emission reduction and achieving the dual-carbon goal.

Close the first regulating valve 730, open the second regulating valve 740, and close the air volume regulating valve 750; the indoor air enters the convection heat dissipation cavity through the heating air inlet 641 at the lower part of the rear plate 640 by natural convection, and after being heated by the heat dissipation component 100, it flows out through the heating air outlet 612 on the top plate 610. At the same time, the heat of part of the hot water heats the front plate 620, the rear plate 640, the left side plate 671, and the right side plate 672 of the box body through convection heat transfer and heat conduction, so that the outer surface temperatures of the front plate 620, the rear plate 640, the left side plate 671, and the right side plate 672 are higher than the indoor temperature, thereby heating the indoor air by radiation. The specific adjustment process is as follows: The information processing module of the controller 710 automatically compares the measured value of the temperature sensor in the on-site control panel 720 with the indoor temperature set value, and automatically controls the opening or closing of the second regulating valve 740, so as to automatically adjust the hot water flow rate through the heat dissipation component 100 to keep the indoor temperature at 5°C.

[0058] In summary, an induced heat exchange chamber and a natural convection heat dissipation chamber are provided inside the box body of this embodiment. Indoor air can be induced by primary air to enter the induced heat exchange chamber and be heated or cooled by the heat exchange coil 200, or enter the induced heat exchange chamber by natural convection and be heated by the heat exchange coil 200. Indoor air can also be heated by the heat dissipation component 100 in the natural convection heat exchange chamber. By optimizing and combining the functions of the inducer and the radiator, cold air can be used for cooling in summer, hot air can be used for heating in winter, or it can be transformed into a radiator to supply heat in a radiation and convection manner, improving the comfort of heating.
