Embodiment 1

[0038] Embodiment 1 of the present invention is a kind of ventilator of the rotary duct type structural form that is used for indoor and outdoor ventilation of various buildings, as shown in Figure 1, 2, it comprises casing 10, places in casing The heat exchange core 30, the air exchange device 40 and the electric control part 50 are equipped with a fresh air outlet 11 and an air exhaust outlet 14 communicating with the outdoor, an air supply outlet 12 and a return air outlet 13 communicating with the room on the wall of the casing 10; the outdoor fresh air It enters from the fresh air outlet, passes through the heat exchange core, and sends it into the room from the air supply port to form a fresh air flow. The indoor dirty air enters from the return air outlet, passes through the heat exchange core in the opposite direction, and is discharged from the air exhaust port to form a dirty air flow. The air exchanging device 40 allows the fresh air flow and the dirty air flow to al...

Embodiment 2

[0049] Embodiment 2 of the present invention is a ventilator with a rotary wheel structure, as shown in FIG. 3 . The working principle, shell structure and breathable material of this example are the same as Example 1, the difference is:

[0050] There are partitions 15 and 16 perpendicular to each other in the housing 10 to divide the inner cavity of the housing into four sub-chambers 17a, 17b, 18a, 18b, and the fresh air outlet 11 and the air supply outlet 12 communicate with the sub-chambers 17a and 17b respectively. , they form the fresh air channel, the air return port 13, the air exhaust port 14 communicate with the sub-chambers 18b, 18a, and they form the air exhaust channel; there is a round hole in the center of the partition 16; the heat exchange core 30 is a disc-shaped runner 30b, which is movable It is placed in the circular hole at the center of the partition 16 and is dynamically sealed with it. The runner 30b includes a disc-shaped frame 31, a rotating shaft 32...

Embodiment 3

[0053] Embodiment 3 of the present invention is a ventilator with a rotary valve plate structure, as shown in FIGS. 4 , 5 , 6 , 7 and 8 . The working principle and heat exchange material of this example are the same as Example 1, the difference is:

[0054]The fresh air outlet 11 and the exhaust outlet 14 of the casing 10 are arranged at the lower part of the rear wall, the air supply outlet 12 and the return air outlet 13 are arranged at the upper part, and the inner cavity of the casing has a partition 19 to divide the inner cavity of the casing into two sub-chambers 19a , 19b, the new air outlet 11 and the exhaust outlet 14 are divided into four air outlets 11a, 11b and 14a, 14b, and each air outlet is provided with an inwardly opened one-way automatic door 111 connected with the rear wall of the cabinet with hinges and The one-way automatic door 141 that opens outwards, they automatically open or close under the air pressure difference inside and outside the casing and the...

Abstract

The invention relates to an energy-saving ventilator for ventilating inside and outside an air conditioner room. The energy-saving ventilator comprises an enclosure (10), a heat exchange core (30), an air exchange device (40) and an electric control component (50), wherein the wall of the enclosure (10) is provided with a fresh air port (11) and an exhaust port (14) communicated with the outside and an air supply port (12) and an air return port (13) communicated with the inside; and through the air exchange device (40), the fresh air entering from the fresh air port and the polluted air entering from the air return port alternately exchange heat through each part of the heat exchange core from the opposite direction, and then are delivered into the inside through the air supply port and exhausted to the outside through the exhaust port. The energy-saving ventilator is characterized in that the heat exchange core is air filter cotton made of a fiber material, wherein heat exchange core contains a phase change substance of which the phase change temperature is between the indoor temperature and the outdoor temperature of the air conditioner room, the phase change substance is phase change salt or phase change polymer, and the phase change substance is added into the fiber material by using a filling method or a padding method, a microcapsule blending method or a microcapsule glue spraying method. The energy-saving ventilator has the advantages of high heat exchange efficiency, low cost, easy cleaning, long service life and capability of purifying air, so the energy-saving ventilator can be widely applied to various buildings and serve as an ideal energy-saving ventilating device for the environment-friendly energy-saving affairs.

Description

Technical field: [0001] The invention relates to a ventilation device for indoor and outdoor air exchange in buildings, in particular to an energy-saving ventilator for indoor and outdoor ventilation in heating and cooling air-conditioning rooms, which can recover the air-conditioning energy carried by the exhaust gas. Background technique: [0002] Air-conditioned rooms in buildings are often closed due to the needs of heat preservation and energy saving, and the air quality is very poor, resulting in the well-known air-conditioning disease. In order to protect people's health, it is necessary to ensure that the air-conditioned room has good ventilation. In order to recover the air-conditioning energy taken away by the exhaust, the only way at present is to use energy recovery fresh air ventilators. There are various forms of fresh air ventilators, but the plate ventilator is the most commonly used at present, and there are also a very small number of rotary ventilators. T...
