Embodiment 1

[0059] In order to describe the present invention more clearly and completely, a household fresh air unit will be explained in more detail below in conjunction with the accompanying drawings—according to a specific embodiment of the present invention.

[0060] as in the present invention figure 1 As shown, the present invention discloses a household fresh air unit that integrates humidification and dehumidification with a two-way flow air system, including a controller, a water system and a wind system, the controller is connected to the water system and the wind system, and the water system The system includes a first electric three-way valve 8, a second electric three-way valve 13, a fluorine water heat exchanger, and a water surface cooler. The wind system is a two-way flow air system, and the household fresh air unit includes a PM2.5 filter and Heat recovery device, the two-way flow air system also includes a return air inlet, a fresh air inlet, a return air exhaust port a...

Embodiment 2

[0075] What is more optimized is a new type of fresh air unit that separates humidification and dehumidification of the two-way flow air system.

[0076] Such as figure 2 shown in accordance with the present invention figure 1 The structural diagram of the household fresh air unit with separate humidification and dehumidification of the two-way flow air system:

[0077] On the basis of Example 1, the humidifier and fresh air blower components are separated and used separately, and users can decide according to their own needs.

[0078] In the new type of fresh air unit with two-way flow air system that separates humidification and dehumidification, an external separate humidifier is installed behind the fresh air outlet, and a PM2.5 filter is installed at the rear of the humidifier. The PM2.5 filter is high-efficiency or sub- The high-efficiency filter, combined with the low-efficiency filter at the fresh air inlet, can ensure that the PM2.5 filtration efficiency reaches mo...

Embodiment 3

[0083] What is more optimized is a new type of fresh air unit with a one-way air flow system humidification and dehumidification integrated machine.

[0084] Such as Figure 6 shown in accordance with the present invention figure 1 The structural diagram of the household fresh air unit with integrated humidification and dehumidification of the one-way air flow system:

[0085] Compared with Embodiment 1, this embodiment is a new type of fresh air unit with a one-way airflow system humidification and dehumidification integrated machine, canceling the heat recovery device, the return air inlet, and the return air exhaust port, and adding an external separate outdoor exhaust fan and The outdoor air outlet is used to exhaust indoor dirty air to the outside.

[0086] Such as Figure 8 shown in accordance with the present invention figure 1 Schematic diagram of the operation of the household fresh air unit with integrated humidification and dehumidification of the one-way air fl...

Abstract

The invention discloses a household fresh air unit, which solves the problems in the prior art that PM2.5 cannot be effectively filtered, the temperature of the outlet air, and the humidity content cannot be adjusted. The new household fresh air unit includes outdoor air inlet, fresh air outlet, indoor air inlet, air outlet, PM2.5 filter, heat recovery device, return air filter, water meter cooler, compressor evaporator, compressor Condenser, regulating three-way valve, throttle valve, blower, exhaust fan, controller, electric bypass ventilation valve. The device adopts the method of evaporative refrigeration with a built-in compressor, cooperates with the water-cooled surface cooler and condenser to deeply dehumidify and adjust the temperature of the humid fresh air entering the unit, and prevents the heat recovery module from frosting through the linkage of the temperature and humidity detector and the electric bypass ventilation valve. It ensures that the humidity and temperature of the fresh air outlet are stable and adjustable. It provides a reliable and energy-saving treatment method for the temperature and humidity independent control and adjustable system. The fan can be used in green buildings and meets the use standards of green buildings.

Description

technical field [0001] The invention relates to the field of fresh air units. Background technique [0002] Existing fresh air units do not utilize PM2.5 filter devices, dual cold source technology, and automatic frosting technology for heat recovery modules, resulting in excessive energy consumption, frosting of heat recovery modules, and inability to effectively filter air. [0003] Therefore there is the PM2.5 value that can't filter air in the prior art so as to reach the degree of national standard. And the problem that the heat of indoor exhaust gas cannot be fully utilized for secondary utilization and automatic frosting. Contents of the invention [0004] In order to solve the PM2.5 value that cannot filter the air existing in the prior art to reach the degree of the national standard. As well as problems such as the inability to make full use of the heat of the indoor exhaust gas and to reutilize it, the present invention provides a household fresh air unit for ...
