Product Description

China National Technology Patent Product

The project of China National High Technology Research and Development Plan

The R & D leader is an academician of the Chinese Academy of Engineering

Independently developed lattice-doped nanomaterials with stable performance

Performance decay rate does not exceed 1% within 15 years

ADVANTAGES:

★ High heat insulation while ensuring high light transmission

By nano character of the new material,80% visible light from sunlight come indoor to guarantee natural light needed.

★ Heat insulation

Our new material can barrier 90% infrared which deduce air condition load and lower refrigeration consumption. Meanwhile,it also block Infrared heat energy at high rate from air and ground where air conditioning load mainly generate at cloudy day and night.Regular sunshade methods not possess this function.

★ Maintain temperature

Holding infrared heat energy inside in winter to the purpose that keep indoor warm and reduce heating cost.

★ Anti-UV

Blocks up to 99% of UV rays, avoiding UV harm to human skin and furniture,flooring and curtain color fading.

★ No signal shielding, no light pollution

The energy-saving film is based on nano material. It selectively transmits and absorbs light of various wavelengths in sunlight. There is no metal coating of traditional heat insulation film, so there is no light pollution. No shielding of wireless signals

★ Dry glue system

The mounting glue is made of polyester, which has a large molecular weight, good weather resistance, easy drying, minimal residual solvent, and high cost. Dry glue does not generate bubbles when heated, tearing the protective film is odorless, non-sticky, easy to apply

★ Anti-explosion

Deduce possibility of glass broken to pieces from high above the ground. To aviod human injured by accident in maximum.

★ Service life

A variety of elements are introduced in the preparation of the nanoparticles, and a nano-insulation medium is generated using a gravity machine to ensure that the particle size distribution of the particles is sufficiently narrow and highly uniform, so that the controllability, heat insulation and stability can be achieved status. The heat insulation film produced by the liquid phase transfer technology has a uniform dispersion of the medium and a low heat insulation attenuation rate. After more than 15 years of use, the attenuation rate is about 1%. Our factory accepts customers to re-measure the insulation effect every year, and is responsible for the results.

★ Compared to microwave sputtered metal film

  1. Our Nano Thermal Insulation Film is the third-generation technology thermal insulation film. But sputtered metal film is the second-generation technology film.
  2. With both high light transmission and high heat insulation functions. Sputtered metal film is impossible to achieve both. Good light transmission has poor thermal insulation effect.If good thermal insulation, the light transmission is poor.
  3. Service life. The attenuation rate of our nano film is about 1% more than 15 years. Sputtered film attenuated a certain rate every year till the end of its service.
  4. No metal so no light pollution and no shielding effect on wireless signals. Sputtered film has both.
  5. Can compensate for the infrared heat band that LOW-E glass cannot block. The production process of the sputtered metal film is the same as that of LOW-E glass, and they can block the same band, so the sputtered metal film is basically not helpful for improving the infrared heat band of LOW-E glass.

CAUSES AND CALCULATIONS OF GLASS ENERGY CONSUMPTION

As the thin-walled envelope structure in the building, glass doors and windows play the role of lighting and ventilation. However, it is precisely because of the particularity of glass, that it has become the biggest energy weak link in building use. According to many authoritative organizations, the energy lost through glass doors and windows reaches 40% of the energy consumption of buildings.

★ CAUSES

 As we all know, ordinary glass has only a small blocking effect on the radiation of sunlight. Ultraviolet, visible and mid-near infrared bands of sunlight can pass through glass in a high proportion. Due to the high transmission ratio of visible light, glass has an illumination function. At the same time, due to the direct transfer of a large amount of mid-near infrared heat, additional burden is placed on indoor air-conditioning refrigeration in the summer, resulting in new cooling energy consumption. (The distribution of energy in each band of sunlight is ultraviolet:3%, visible light:44%, and infrared line accounts for 53%)

         In winter, as a kind of thin and light-weight envelope structure material, thermal conductivity of glass is relatively much higher than other envelope structure materials, such as concrete, bricks, etc. This allows more heat to be transmitted through the glass to the outdoors during indoor heating in winter, resulting in excessive loss of heating energy.

Working Principle

The energy-saving film is made of nano metal oxide. The nano-effect of this material makes the visible light band transmittance of sunlight reach 80%, and it blocks ultraviolet rays more than 99%. At the same time, it selectively absorbs the total energy of sunlight and secondary radiation to make the mid-near infrared blocking rate exceeds 90%. Under the premise that the film has limited influence on indoor lighting, it can block the heat of the mid-near infrared rays into the room to the greatest extent, thereby greatly improving the efficiency of air conditioning.

          During the heating in winter, it can also prevent heat from being lost to the outdoors and achieve thermal insulation due to its high blocking effect on the mid-near infrared.

Q = Heat per square meter per hour transmitted by glass   Sc: Shading factor of glass   K: Heat transfer coefficient of glass    Ot: Temperature difference between indoor and outdoor   630: Solar constant in summer

★ CALCULATIONS

Heat per square meter per hour transmitted by glass during the summer due to solar radiation = Q

Q = Ot × k + 630 Sc

Ot: Temperature difference between indoor and outdoor

K: Heat transfer coefficient of glass

630: Solar constant in summer

Sc: Shading factor of glass

Then take 6mm single glass (K = 5.8w/㎡/h Sc = 0.95) as an example, the indoor air-conditioning refrigeration is controlled at 26 ° C, and the outdoor temperature is 36C, so Qt is 10. The heat entering the room through the glass:

Q = 656.5 w/㎡/h

From the above calculations, the following conclusions can be drawn regarding energy savings:

In summer: the heat of ordinary glass entering the room is Q = 643.9w /㎡/ h, and the glass after filming is calculated according to (Sc average 0.42). The heat entering the room is Q = 313.6w /㎡/ h, then it can be calculated: Film-coated glass can reduce the heat of 330.3w / w /㎡/ h into the room, the energy saving ratio is 51%.

Q = Heat per square meter per hour transmitted by glass   Sc: Shading factor of glass   K: Heat transfer coefficient of glass      Ot: Temperature difference between indoor and outdoor   630: Solar constant in summer

★ CALCULATIONS

The heat loss of glass heating in winter = Q

Q = Ot × k

Also taking 6mm single glass as an example, the heating room temperature is controlled at 20℃,Qt set at 20℃:

Q = 20 × 5.8 = 116 w/㎡/h

If in cold area, Qt set at 30℃:

Q = 30 × 5.8 = 174 w/㎡/h

If in cold area, Qt set at 30℃:

If extreme cold region, Qt set at 40℃:

Q = 40 × 5.8 = 232 w/㎡/h

In winter, according to the indoor and outdoor temperature difference of 20℃, the heat lost by ordinary glass is Q = 116w / w /㎡/ h, and the heat lost by glass after film is Q = 98w /㎡/ h, can reduce the heat loss of 18w /㎡/ h, the energy saving ratio is 15.5%.

If calculate according to the summer cooling period of 4 months and the winter heating period of 4 months. The annual energy consumption of ordinary glass is 643.9 × 24 × 120 + 116 × 24 × 120 = 2188512w /㎡. The energy consumption of the glass after the film is 313.6 * 24 “120 + 98 × 24 × 120 = 1185408w /㎡, which can reduce the energy consumption by 1003104w /, and the energy saving rate is 45%. Calculated as the energy consumption of glass accounts for 40% of the energy consumption of whole buildings, ordinary glass can have 18% energy saving rate after film modification.

Therefore, after a maximum of one year, you can recover the cost of purchasing energy-saving films, and can continue to enjoy the benefits brought by energy-saving films for at least 10 years.

Construction Methods

Tips: 

  1. Within 3 days of film installation, do not move the film, and do not scrub the surface of the film with water within 15 days of installation
  2. Due to the water spraying during installation, small bubbles or misty water vapor may be normal within a week, and it will disappear by itself after it is completely dry.
