Detailed Description
The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp, and thus make a clearer definition of the protection scope of the present invention.
In view of the defects in the existing scheme for preventing condensation of the fresh air equipment, the designer deeply analyzes the influence of the three parameters on condensation and the feasibility of adjustment, focuses on the solution of condensation on improving the temperature of the contact part of the air outlet, and innovatively provides the fresh air equipment for preventing condensation, so that the huge energy consumption for heating all air is avoided.
The utility model discloses this prevent technical solution of condensation overview sees, connects at the air outlet contact site of new trend equipment and establishes solid state heater to it is controlled to link to each other with the ventilation controller of new trend equipment, advances in real time monitoring, keeps the temperature that air outlet contact site is higher than dew point temperature with the mode of heating nearby under the condition of air-out temperature and indoor relative humidity. As can be seen from the technical summary, the main points of the anti-condensation solution include: the main bursting point of the condensation prevention is positioned at the contact part of the air outlet, namely the possible position of direct formation and accumulation of the condensation; the supplementary breakthrough point is related to a heating object, air with low heat conduction efficiency is not, the contact part of the air outlet in multiple times is used for improving the heating energy efficiency in a mode of direct heat conduction with solid-state contact.
The solid state heaters described above are of a wide variety of alternative types in practical applications and are almost entirely powered. For visual understanding, as shown in the preferred embodiment of the anti-condensation fresh air device shown in fig. 1 and 2, the solid-state heater is preferably a silicon rubber heating tape 2 with a shape adapted to the shape of the air outlet, and is tightly attached to the inner surface of the air outlet 12 by using heat-resistant adhesive. In particular, the silicone rubber heating belt is controlled to obtain self-heating energy supply from a ventilation controller.
The silicon rubber heating belt is a particularly soft heating belt consisting of nichrome wires and insulating materials, has high design power density, fast heating, high thermal efficiency, long service life and good waterproof performance, can be used for heating, heat tracing and heat preservation of various industrial equipment or pipelines, tank bodies and tanks, and is simple to install, safe and reliable. In the application of the scheme, particularly before the solid-state heater is connected, the silicon rubber heating belt can be cut corresponding to the appearance of the air outlet, so that the air outlet can be installed in a compliant manner without an exposed part, and the attractiveness of the fresh air equipment is guaranteed; and the cutting process also needs to prevent the cutting of the heating wire embedded in the cutting machine.
Certainly, although the silicon rubber heating tape has excellent performance from multiple aspects and is easier to adhere to the contact part of the air outlet, when the silicon rubber heating tape is overheated, the service life of the heating tape is affected, even heated articles can be damaged, the existing silicon rubber heating tape is not provided with a fuse generally, and when the heating tape is in a short circuit condition, a power supply cannot be timely disconnected, and accidents can be caused. From this, further improvement sets up the overheat protection module based on third temperature sensor and relay at the silicon rubber heating band, and among the overheat protection module inserts ventilation controller simultaneously, through predetermineeing certain melting loss threshold value control relay break-make electricity state, when the silicon rubber heating band intensifies and surpasss the melting loss threshold value, the relay separation is interrupted the heating, when the silicon rubber heating band cooling is to melting loss threshold value below, the relay actuation is and continue the heating.
As a basis for realizing the condensation prevention function, the process of monitoring the air inlet temperature, the air outlet temperature and the indoor relative humidity comprises the steps of arranging a first temperature sensor 31 at the air inlet 11 to detect the air inlet temperature T1, arranging a second temperature sensor 32 at the inner side of the air outlet 12 to detect the temperature T2 of a contact part, arranging a fourth sensor 33 used for detecting the indoor relative humidity at the bottom side of the air outlet, connecting each sensor into a ventilation controller, and independently initializing along with the starting of the fresh air equipment 1 and feeding back a real-time monitoring result by a signal.
In winter, the outdoor environment temperature is relatively low, and in this embodiment, it is assumed that when the inlet air temperature is less than 5 ℃, the fresh air device produces more condensation under the indoor normal temperature condition. After the fresh air equipment is started, the ventilation controller monitors that when the air inlet temperature T1 is less than 5 ℃, the silicon rubber heating belt is switched on and provides electric energy for the silicon rubber heating belt, and the contact part of the air outlet is heated. The second temperature sensor detects the temperature T2 in real time along with the rise of the temperature T2, meanwhile, the ventilation controller sets a threshold value for judgment according to the indoor relative humidity a% RH monitored by the fourth sensor, and if the temperature T2 is higher than the dew point temperature, the silicon rubber heating belt stops heating; if the temperature T2 is lower than the dew point temperature, the silicone rubber heating belt continues to heat, so that the clamping temperature T2 is kept slightly higher than the dew point temperature.
In addition to the preferred embodiment of the above-mentioned anti-condensation fresh air device, the solid heater may also be a ceramic heating sheet customized to the shape of the air outlet, and is tightly attached to the inner surface of the air outlet by using a heat-resistant adhesive, or is embedded and clamped to the air outlet. Although the difficulty of shape adaptation of the air outlet shape is larger, the heat resistance range of the heater body is larger relative to the temperature difference between the indoor and the outdoor, so that the overheating protection can be omitted.
To sum up about the utility model discloses prevent embodiment detail of condensation new trend equipment, the progressive nature that possesses is: the improved structure is intensively positioned at the contact part of the air outlet and adopts direct solid-state heating to improve the heat conduction efficiency, thereby realizing the prevention of condensation with low-power energy consumption. Meanwhile, the solid-state heater is small in size and thin in thickness, can be processed according to the shape of the air outlet in an adaptive mode, and has the advantages of convenience in installation, small occupied space and the like.
In addition to the above embodiments, the present invention may have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of the present invention.
