Below by way of citing, the present invention is described further.
By taking Xi'an as an example, the outdoor calculating temperature that heats is -3.4 DEG C, 18 DEG C of indoor calculating temperature.Room length, width and height having a size of
3.2m × 3.2m × 2.7m, door is having a size of 0.8m × 2.0m, and window is having a size of 1.5m × 1.5m.Daytime, solar energy double-sided coil pipe store
The warm bed of heat meets indoor heat load demand to indoor offer heat, and room thermic load mainly includes building enclosure heat consumption and cold
Wind permeates heat consumption.According to " severe cold and cold district energy Saving Design of Residential Buildings standard JGJ26-2010 " for meeting energy saving mark
Quasi- heat-preserving wall, being computed rear building enclosure heat consumption is about 509.5W, and heat loss by infiltration is about 25.6W, i.e. room heat
Load QLAbout 535.1W.
(1) when bed body air outlet meets following equation between daytime, solar energy double-sided coil pipe accumulation of heat is warmed up between bed is able to satisfy daytime and is heated
Demand:

Phase change heat storage material is made of paraffin and high density polyethylene (HDPE), and phase transition temperature is 26 DEG C, density and latent heat of phase change point
It Wei not 1510kg/m3With 1.8 × 105J/kg, the present invention in phase change heat storage material floor space be about 0.9 × 0.19=1.71m2, thick
Degree is 60mm, and volume is about VPCM=0.103m3, then the ideal amount of stored heat of phase-change material is QPCM=1510 × 0.103 × 1.8 ×
105=2.80 × 107J。
Assuming that by operating condition operation 16h (6:00-22:00) between daytime in a whole day, night operating condition runs 8h (22:00-next day
6:00), solar irradiation can give coil pipe to provide 8h (9:00-17:00) heat, i.e. the amount of stored heat of phase-change material will meet between 8h daytime
With 8h night operating condition.Night only needs to heat around bed body, therefore night institute's calorific requirement is equivalent to room temperature is 10 DEG C and goes along with sb. to guard him
Structure heat dissipation capacity calculates to obtain QLN=345.8W.Between 8h daytime and 8h night operating condition room institute's calorific requirement is (QL+QLN)×8×3600
=2.54 × 107J<QPCM, therefore amount of stored heat is able to satisfy thermal load demands.
(3) between daytime when solar irradiation coil pipe unit time heating load:
Qg=cg×ρg×ug×Ag×(t2-t1)
Q in formulag--- coil pipe unit time heat dissipation capacity, W；
cg--- the specific heat at constant pressure of liquid working substance, J/ (kg DEG C), 4.2 × 103J/(kg·℃)；
