Hereinafter, embodiments according to the present application will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, a fresh air conditioner according to an embodiment of the present application includes a housing 1.

The shell 1 is in a cuboid column shape and forms the overall appearance of the fresh air humidity regulator. In other embodiments, the housing 1 may be in other vertical shapes such as a cylinder, an elliptic cylinder, and the like. That is, the height direction dimension of the housing 1 is larger than the lateral direction dimension in this application.

In terms of component composition, the housing 1 includes a housing body 1a and a door body 1b.

One side of the case body 1a is open, and for convenience of description, the open side of the case body 1a is defined as a front side. Specifically, the case body 1a includes a top plate forming a top configuration, a bottom plate forming a bottom configuration, a rear plate located between the top plate and the bottom plate, and two side plates located on both sides of the rear plate.

The door body 1b is rotatably coupled to the front side of the case body 1a so that the case body 1a can be opened or closed. When the door body 1b is in the open state, the operations such as maintenance and replacement of the components inside the case body 1a are facilitated.

In other embodiments, the housing 1 may be replaced with a front plate instead of the door body 1b, and at this time, the front plate (or the rear plate, the side plate, or the like) may be removed for maintenance and replacement operations.

A return air duct 11 and a fresh air duct 12 are formed in the housing 1. The return air duct 11 is used for circulating indoor air, discharging indoor air (also referred to as indoor return air) to the outside, and the fresh air duct 12 is used for circulating outdoor air, and sending outdoor air (also referred to as outdoor fresh air) to the inside, thereby realizing a fresh air function of indoor ventilation.

Specifically, a return air inlet 13, a return air outlet 14, a fresh air inlet 15 and a fresh air outlet 16 are arranged on the shell 1. The return air inlet 13 and the return air outlet 14 are respectively communicated with the return air duct 11, and the fresh air inlet 15 and the fresh air outlet 16 are respectively communicated with the fresh air duct 13; simultaneously, the fresh air inlet 15 and the return air outlet 14 are communicated with the outside of a room, and the fresh air outlet 16 and the return air inlet 13 are communicated with the inside of the room. Thus, the indoor return air is discharged to the outside through the return air inlet 14, the return air duct 11 and the return air outlet 14, and the outdoor fresh air is sent to the indoor through the fresh air inlet 14, the fresh air duct 12 and the fresh air outlet 16.

Referring to fig. 3, in terms of construction materials, the housing 1 may include an outer frame 1c and a wind tunnel insulation layer 1d. The frame 1c can adopt sheet metal parts, the material of the air channel heat preservation layer 1d can be EPP air channel foam, the air channel foam is shaped into an air return air channel 11 and a fresh air channel 12, and meanwhile, the air channel foam can also preserve heat, so that heat release in the air channel is avoided.

The summer wet load comprises fresh air, human body moisture dispersion, moisture brought by permeated air (door and window seams), various wet surfaces of non-enclosure structures, moisture dispersion of liquid level or liquid flow (toilet), moisture dispersion of food or gas materials (kitchen) and the like, wherein the fresh air and the human body account for the great proportion; the winter wet load only comprises the humidity (door and window seams and the like) brought by fresh air and permeated air, so that the humidity regulation of a fresh air system is very important;

in addition, humidification or moisture preservation is required in winter in northern areas (the indoor dryness is aggravated if only fresh air is subjected to temperature treatment); the requirements for humidification in winter in the south area are smaller, but the requirements for dehumidification in summer are larger, and even in low-temperature and high-humidity weather (returning to the south), the requirements for dehumidification are stronger. Therefore, the fresh air humidity is required to be subjected to differentiation treatment;

in addition, in winter, the air is dry due to insufficient humidity, so that on one hand, the mucous membrane of the respiratory system of a human body can be damaged, and viruses easily invade the human body; on the other hand, the moisture dispersion of the human body is increased, when the moisture content of the skin is reduced to below 10%, the skin is dry, and is easy to crack and itch, so that a plurality of skin problems occur; while winter humidification can significantly alleviate the above-mentioned discomfort. The problems of mildew on the surfaces of indoor objects, food deterioration acceleration and the like can be caused by high temperature and high humidity in summer, and the problems can be solved by dehumidification in summer.

Therefore, in order to meet the requirements of various scenes, the fresh air humidifying machine has a fresh air function and a humidifying and temperature regulating function.

Referring to fig. 2, 8, 9, a fresh air conditioner according to an embodiment of the present application includes a refrigerant system 2 and a runner assembly 3.

The refrigerant system 2 comprises a compressor 21, a four-way valve 22, a first heat exchanger 23, an expansion valve 24 and a second heat exchanger 25.

Wherein the first heat exchanger 23 is arranged in the return air duct 11, and the second heat exchanger 25 is arranged in the fresh air duct 12. The second heat exchanger 25 is used as a condenser when the first heat exchanger 23 is used as an evaporator, thereby realizing fresh air heating, and the second heat exchanger 25 is used as an evaporator when the first heat exchanger 23 is used as a condenser, thereby realizing fresh air cooling. The cooling and heating principle of the refrigerant system of the present application is the same as that of the air conditioning system, and will not be described in detail here.

The runner assembly 3 is used for realizing humidity adjustment of air, and comprises a runner 30, wherein the runner 30 is made of an adsorption material, and can realize temperature swing adsorption, namely low-temperature moisture absorption and high-temperature moisture release, and simultaneously, the refrigerant system provides low-temperature and high-temperature environments for the runner 30.

The wheel 30 always has a portion a located in the return air duct 11 and another portion B located in the fresh air duct 12 during stationary and rotating conditions. Indoor return air flows through part A of the rotating wheel 30 in the return air duct 11, and outdoor fresh air flows through part B of the rotating wheel 30 in the fresh air duct 12.

When the fresh air with higher relative humidity passes through the rotating wheel 30 during refrigeration and dehumidification, the adsorbed material absorbs moisture to realize the fresh air dehumidification; when heating and humidifying, the moisture of indoor return air is adsorbed and recovered by the rotating wheel, and then fresh air with lower relative humidity desorbs the moisture through the rotating wheel, so that humidifying is realized. The rotating wheel rotates according to a preset rotating speed so as to form a repeated fresh air dehumidifying or humidifying treatment process.

According to the calculation formula of the body temperature, in winter, when the indoor temperature is more than or equal to 15 ℃, the relative humidity is increased, the body temperature is also increased, even if the room temperature is slightly lower, the body temperature cannot feel cold (for example, the indoor temperature is 21.1 ℃/30%RH, the body temperature is 21.1 ℃, and when the relative humidity reaches 60%, the body temperature is 22.2 ℃); in summer, the indoor relative humidity is reduced, the body temperature is also reduced (for example, the indoor temperature is 28.9 ℃/70%RH, the body temperature is 32.2 ℃, and when the relative humidity is reduced to 40%RH, the body temperature is only 28.3 ℃), so that a fresh air system is adopted to bear indoor latent heat load, and the air conditioning system operates at a slightly higher evaporation temperature, thereby obviously improving the actual operation energy efficiency of the whole unit.

In this application, the first heat exchanger 23 and the second heat exchanger 25 are referred to as heat exchanger assemblies.

The heat exchanger component and the rotating wheel component 3 are vertically arranged in the shell 1, so that the transverse size of the shell 1 can be reduced, and the vertical structure of the fresh air humidity regulator is realized.

Compared with the traditional suspended ceiling type mounting structure, the vertical structure has smaller transverse dimension, so that the occupied space is small, and the occupied area is not more than 0.27m ² Can meet the demand of the house decoration market on miniaturized products.

In addition, the humidifying mode adopts a waterless humidifying technology, the humidifying function can be realized by utilizing condensed water collected by the evaporation side rotating wheel, the humidifying cost is relatively low, and a user does not need to use a water receiving pipe and install a water purifier for humidifying.

In the application, the occupied space of the damping machine to the ground can be reduced by jacking all the air openings. Because, if the air port is provided with the side face and the outer air connecting pipe is added, the transverse size of the damping machine is necessarily increased, the transverse size of the damping machine is increased, and the occupied area is also increased.

Moreover, all overhead air inlets, the outer air connecting pipe can directly enter the suspended ceiling, the space occupied by the air pipe on the suspended ceiling is relatively small, the air pipe does not belong to vulnerable parts, and frequent maintenance is not needed. Compare in the new fan of traditional suspension type divide bellows and amortization tuber pipe all hide at the furred ceiling inside can occupy very big partial furred ceiling space together with new fan body, this application releasable layer is high, improves user's comfort, and convenient maintenance.
