Fourier heat conduction law: q ═ λ (α t/α x) n

Wherein, q: a heat flux density; λ: coefficient of thermal conductivity; α t/α x: a temperature gradient; n: normal unit vector on the isotherm.

As shown in fig. 6a, without the thermal damping layer, the energy conversion layer 1 is in direct contact with the radiation panel 4; due to the lack of y-direction heat conduction by the thermal damping layer 2, the isotherm T4 of the radiating panel 4 is more curved, i.e. the surface temperature difference is larger.

As shown in fig. 6b, a thermal damping layer 2 is provided between the transduction layer 1 and the radiation panel 4; according to the fourier heat conduction law, in the isotropic thermal damping layer 2, if heat enters the thermal damping interior from the transduction layer 1, the passing heat flow density q is maximum due to the temperature gradient (the isotherm shows a curve in the x-y section) existing in the x and y directions near the left side. Due to the integral accumulation effect, it can be calculated that: when the heat reaches the right boundary of the thermal damping layer 2, the isotherm tends to be flat, that is, the temperature of the right boundary of the thermal damping layer 2 tends to be uniform. The isotherm T4 of the radiation panel 4 is flatter.

Therefore, the radiation heat quantity at the tail end of the radiation air conditioner additionally provided with the thermal damping layer 2 is more uniform, and the radiation effect is better.

Theoretical basis of isotherms: a common heat conducting structural member is a copper tube, as shown in fig. 6c, if the thermal damping layer is regarded as a half-side cylindrical wall, the copper tube and the thermal damping layer are similar to a one-dimensional steady-state heat conduction process of a single-layer cylindrical wall, and the temperature distribution (t1-t2) in the thermal damping layer is in a logarithmic curve.

According to the Fourier heat conduction law, the uniformity degree of the right side boundary of the thermal damping layer is positively correlated with the heat conduction coefficient lambda and the thickness x of the thermal damping material. However, as the thermal conductivity λ or the thickness x increases, the efficiency of heat conduction decreases; when the thermal damping material adopts air, the increase of the thickness x also increases the thermal convection, and is not beneficial to the flattening of the isotherm. However, if the air layer thickness x is too small, the heat conduction efficiency will be improved, but the temperature difference between the energy conversion layer and the surface of the radiation panel will be small, the surface of the radiation panel will generate dew, and the temperature of the cold source will need to be increased during cooling, resulting in high energy consumption and high cost.

Therefore, synthesize above factor, both guarantee heat conduction efficiency, also consider energy-conserving effect simultaneously, the utility model discloses the parameter of confirming thermal damping layer is: the thickness is in the range of 0.6mm-2.4 mm. More preferably, the thickness of the air layer is 1.0mm to 2.4 mm.

Right the utility model discloses a radiation air conditioner is terminal and do not have the radiation air conditioner on thermal damping layer and terminal the contrast test, all lets in 8 ℃ chilled water in two terminal transduction layers of radiation air conditioner, the utility model discloses a radiation air conditioner is terminal air bed thickness sets up to 1.2mm, selects on the radiation panel at random 5 points and carries out temperature measurement, and the temperature that records is 22.0 ℃, 21.8 ℃, 22.0 ℃, 21.8 ℃ and 21.8 ℃ respectively, and the face difference in temperature of radiation panel is the biggest only 0.2 ℃, and the radiation panel temperature is more even. The temperatures of all points of the radiation panel at the tail end of the radiation air conditioner without the thermal damping layer are respectively 12.0 ℃, 11.1 ℃, 13.2 ℃ and 12.9 ℃, the temperature difference of the panel surface of the radiation panel is 2.1 ℃ at most, the temperature difference is 0.9 ℃ at least, and the temperature difference of all points is large.

At present, a common radiation air-conditioning system does not have a thermal damping layer (namely, a transduction layer is directly attached to a radiation panel), and the actually measured temperature difference delta T between the surface of the transduction layer and the surface of the radiation panel_{Inside and outside}Substantially below 5 ℃. Because the problem of dewing on the surface of the radiation panel needs to be overcome, the temperature of the radiation panel cannot be lower than the dew point temperature, the temperature of chilled water cannot use a chilled water system at 8-10 ℃, and a 16-18 ℃ high-temperature chilled water system needs to be configured, so that high energy consumption and high manufacturing cost are caused.

The utility model discloses a radiation air conditioning system, owing to adopted specific thickness and coefficient of heat conductivity's thermal damping layer (0.6mm-2.4 mm's air bed), under the same experimental condition, the difference in temperature delta T of actual measurement heat transfer layer and radiation panel face_{Inside and outside}Substantially greater than 14 deg.c. The minimum water inlet temperature can be 6 ℃, and 8-10 ℃ is generally adopted, so that the conventional chilled water system can be used, a high-temperature chilled water system is not required to be additionally arranged, the energy consumption is low, the manufacturing cost is low, and more energy is saved.

Setting the temperature difference delta T between the energy conversion layer and the panel surface of the radiation panel in a control experiment_{Inside and outside}The test is carried out, the experimental environment is that the indoor temperature is 28.5 ℃, the relative humidity is 60%, the corresponding dew point temperature is 20 ℃, and the 10 ℃ chilled water is input into the transduction layer at the tail end of the radiation air conditioner:

1. the temperature of the surface of the radiation panel is 24.2-24.7 ℃, is higher than the dew point temperature, does not condense, can normally work, and the temperature difference delta T between the energy conversion layer and the surface of the radiation panel_{Inside and outside}And the surface of the radiation panel is far away from the surface of the air layer and is higher than 14 ℃.

2. The control group is the end of the radiation air conditioner without air layer, the temperature of the surface of the radiation panel is measured to be 12.9-14.6 ℃ and is lower than 15 ℃, the surface of the radiation panel generates condensation, and the temperature difference delta T between the energy conversion layer and the surface of the radiation air conditioner_{Inside and outside}Less than 5 ℃. Therefore, the radiation panel of the control group could not work with 10 ℃ chilled water under this indoor condition.

Therefore, the air layer with the thickness of 0.6mm-2.4mm is arranged as the thermal damping layer, so that the temperature difference between the surfaces of the energy conversion layer and the radiation panel is larger, the chilled water temperature for cooling is higher, the hot water temperature for heating is lower, the energy consumption is low, and more energy is saved.

The utility model discloses a thermal-protective layer and thermal damping layer constitute the radiation air conditioner end of asymmetric heat transfer to the thermal-protective layer adopts thickness to experiment for the radiation air conditioner end of 10 mm's EPP foaming insulation board (foaming polypropylene board), thermal damping layer adoption 1.2mm air bed. The experimental environment was at an indoor temperature of 28.5 deg.C, a relative humidity of 60%, and a corresponding dew point temperature of 20 deg.C. After the chilled water with the temperature of 10 ℃ is input into the transduction layer at the tail end of the radiation air conditioner for 1 hour, the actually measured plate surface temperature of the radiation panel is 24.2-24.7 ℃, and the outer surface temperature of the heat insulation layer is 28.0-28.3 ℃. Because the thermal resistance of insulating layer is higher, and the thermal resistance of thermal damping layer is lower, consequently more heat can be followed thermal damping layer one side and passed into the energy conversion layer, is absorbed the heat by the refrigerated water, makes the face temperature of radiation panel lower, thereby the utility model discloses a radiation air conditioner end of antisweat can freely adapt to various operational environment's antisweat high efficiency operation.

Moreover, through the detection, the utility model discloses a panel infrared transmittance is < 50%, can improve whole heat transfer efficiency.

To sum up, the utility model discloses consider from radiant efficiency (heat-transfer ability), anti-condensation ability and energy-conservation nature tripartite, improved the tripartite performance simultaneously, improved radiant efficiency, anti-condensation, moreover the energy consumption is littleer, more energy-conserving, make the terminal comprehensive properties of radiation air conditioner reach the optimum.
