Embodiment 1

[0048] This embodiment is a ventilation and air conditioning fan with a rotating valve plate structure, such as figure 1 , 2 , 3, 4, and 5, it is used for air humidification and cooling or energy recovery and ventilation and purification in air-conditioned rooms. It includes a casing 10, a fan part 20 placed in the casing, and a medium for exchanging heat or evaporating water. The air-permeable carrier 30 and the electric control part 60 of the water curtain.

[0049] The rear wall of the casing 10 is provided with a fresh air outlet 11 and an air exhaust outlet 14 communicating with the outside of the window, and the front wall or side wall is provided with an air supply outlet 12 and a return air outlet 13 communicating with the room. The inner cavity of the casing is equipped with a breathable carrier 30 The carrier chamber 15. A partition 153 divides the carrier chamber 15 into two sub-carrier chambers 151 and 152 in the carrier chamber 15, and the gas-permeable carrier ...

Embodiment 2

[0064] This example is another structure of rotating valve plate, such as Image 6 , 7 As shown, it is basically the same as Example 1, and the names and functions of the labels in the figure are also the same as figure 1 , 2 Same, the difference is:

[0065] The air supply port 12 and the air return port 13 are all located on the front wall of the carrier chamber 15, and they are divided into two ports by the partition plate, and each port is provided with an inwardly or outwardly open door that is connected with the wall of the carrier chamber by a hinge. The one-way automatic doors 131, 121 are automatically opened or closed under the air pressure difference inside and outside the casing and the action of dead weight.

[0066] The fresh air fan 21 and the exhaust fan 22 of the fan unit 20 are duplex fans, which are formed by driving two coaxial centrifugal wind wheels 211 and 221 with a biaxial extension motor 23, and each centrifugal wind wheel is contained in a volute;...

Embodiment 3

[0070] This embodiment is a kind of ventilating and air-conditioning fan of rotary duct type structure, such as Figure 8 , 9 , 10, it is basically the same as the case of Example 2, the material of the breathable carrier and the fan, the main differences are:

[0071] The air-permeable carrier 30 is integrally fixed and filled in the carrier chamber 15;

[0072] The air distribution device 40a includes an upper air channel 45, a lower air channel 46, an upper air distribution plate 47, a lower air distribution plate 48, and a driving mechanism 44a for driving them to rotate, which are arranged on the upper and lower sides of the air-permeable carrier 30;

[0073] The upper and lower air ducts are sleeves with a variable load surface with a round opening at one end and a semicircular opening at the other end. The round opening of the upper air duct is connected to the air inlet of the fresh air fan 21, and the round opening of the lower air duct is connected to the fresh air ...

Abstract

The invention provides a multifunctional ventilation air-conditioning fan which is used for air wetting and cooling or energy recovery and ventilation of an air-conditioning room. The multifunctional ventilation air-conditioning fan comprises a machine shell (10), a fan component (20), a ventilated carrier (30) of a medium for heat exchange or water certain for water evaporation, an air distributing device (40), a water supply system (50) and an electronic control component (60); a fresh air inlet (11), an air outlet (14), an air distributor (12) and a return air inlet (13) are arranged on the wall of the machine shell; the ventilated carrier is made of air filtering cotton comprising outlast containing a phase-change substance, wherein the phase change temperature of the phase-change substance is between the indoor temperature and the outdoor temperature of the air-conditioning room, the phase-change substance generates solid-liquid phase change when heated or cooled, the phase change can absorb or release large amount of latent heat, and therefore, large amount of heat energy can be transmitted between two flows of heat exchange air. The invention can be implemented in the structure types of a rotary valve type, a rotating wind channel type, a scroll type and a rotating wheel type and has the advantages of simple structure, low production cost and multiple functions of energy saving and ventilation, cooling and air wetting and fresh air purification; and moreover, the multifunctional ventilation air-conditioning fan can completely replace an air conditioner in a dry area and greatly save equipment investment and operation cost, therefore the multifunctional ventilation air-conditioning fan is an economical, environment friendly, high-efficiency and energy-saving product and has high social and economic benefits.

Description

Technical field: [0001] The invention relates to an indoor air treatment device, in particular to an evaporative cooling fan with the functions of exchanging air indoors and outdoors and recovering exhaust energy. Background technique: [0002] Air-conditioning fans (also known as air-conditioning fans, the standard name is evaporative cooling fans) are energy-saving products widely used in households or public places in recent years for evaporative cooling of water. Its working principle is to use flowing air to flow through a breathable material ( Commonly known as water curtain) to promote its water vaporization, the water vaporization process will absorb a large amount of heat, so that the water temperature decreases, and the air also undergoes an isenthalpic change, the temperature decreases and the absolute humidity increases, that is, the sensible heat decreases and the latent heat increases. Change, that is to say, it can only cool down, not cool. However, because n...
