Problems solved by technology

The above-mentioned designs are essentially two-layer radiant plate designs, and only heat transfer tubes are arranged on the inner layer. This type of design only alleviates the problem of condensation water to a certain extent, but requires additional special dehumidification devices, and the operating temperature Restricted, twice radiation causes radiation to add a layer of thermal resistance, low heat transfer efficiency, and slow response time

Embodiment 1

[0031] See attached Figure 1-5 As shown, a droplet-driven radiant air conditioner in this embodiment includes a radiant plate 1, a heat transfer tube 2, a thermal insulation plate 3, and a liquid collection tank 5; On the ceiling: the heat transfer tube 2 is arranged on the inner surface of the radiant panel 1 , and the heat transfer tube 2 is connected with the air-conditioning system to guide the cold / heat medium provided by the air-conditioning system into the radiant panel 1 . The radiant panel 1 has a radiant surface 4 in contact with the air; the radiant panel 1 directly exchanges heat with people or the indoor environment through the radiant surface 4 through convection and radiation, so the heat exchange efficiency is high, and the cooling and heating response is rapid. Water vapor in the air is allowed to condense on the radiating surface 4 to form condensed water;

Embodiment 2

[0040] Such as Figure 6 As shown, the difference from Embodiment 1 is that the radiant panel 1 is arranged vertically as a whole, and the radiant panel 1 can be flat or arc-shaped; the radiant panel 1 can be arranged in an arc-shaped or vertical Combined with surface design, the driving force of the liquid at this time takes priority over gravity. The surface of the radiant plate 1 is coated with a coating to control the contact angle of the liquid droplets on the surface of the radiant plate 1 , so that the liquid droplets will not fall directly, but also facilitate the liquid droplets to slide into the liquid collection tank 5 driven by gravity.

[0041] In addition, in this embodiment, the inlet of the heat transfer tube 2 can be designed at the lower part of the radiant plate 1, and the outlet can be designed at the upper part of the radiant plate 1, so as to accelerate the liquid droplet movement by using thermal capillary force. According to the principle of thermocapi...

Abstract

The invention discloses a droplet-driven radiation air conditioner. The droplet-driven radiation air conditioner comprises a radiation panel, a heat transfer pipe, an insulation board, a liquid collecting tank and a liquid discharge port; the heat transfer pipe is connected with an air conditioning system; the radiation panel directly transfers the heat / cold quantity to an indoor environment and human bodies through convection and radiation, and secondary heat transfer does not exist; the radiation panel allows vapor in air to condense to form condensed water on the surface thereof; a surface coating is arranged on the surface of the radiation panel for guaranteeing the condensed water to form droplets with uniform and controllable sizes; and through applying electrostatic force and the like or using such principles as dielectric wetting, the condensed water droplets are driven to enter the liquid collecting tank, and are discharged by the liquid discharge port. The droplet-driven radiation air conditioner is simple in structure, high in heat transfer efficiency, fast in response speed, high in human body comfort level and obvious in energy saving effect; and a system can automatically regulate indoor humidity without needing special humidity monitoring and dehumidifying systems, and is free of noise, simple in construction and convenient to maintain.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, in particular to a droplet-driven radiation air-conditioning. Background technique [0002] Traditional indoor air conditioners mostly use convective heat transfer to achieve cooling or heating. Convective heat transfer has many disadvantages, such as the heat exchange air blowing through the human body, which affects the comfort of the human body; the energy consumption is too high to achieve the same cooling and heating comfort; the indoor fan There is inevitably a certain amount of noise, and the accumulation of dust and bacteria. [0003] With the improvement of people's living standards, radiant air conditioners are a better air conditioner for indoor cooling and heating. Radiation air conditioning refers to reducing (or raising) the temperature of one or more surfaces in the inner surface of the enclosure structure to form a cold (hot) radiation surface, which is ca...
