The method comprises the following steps that 1, a solar panel is adopted for collecting sun light energy to obtain the total energy Q1 radiated by the sun in the unit time t; 2, in the first unit time t, the water temperature raising temperature delta T1 in a vacuum pipe is detected, in the second unit time t, the water temperature raising temperature delta T2 in the vacuum pipe is detected, ..., in the n-th unit time t, the water temperature raising temperature delta Tn in the vacuum pipe is detected, and n is a positive integer; 3, the average water raising temperature delta T in the vacuum pipe in the unit time t is calculated, and delta T meets a formula that delta T=(delta T1+delta T2+...+delta Tn)/n; 4, the energy Q2 required by raising the temperature delta T of the water quantity in the vacuum pipe in the unit time t is calculated; 5, the calculation is carried out according to (Q1-Q2)/Q1*100%, and the heat loss value is obtained.
Description
Technical field
The present invention relates to a kind of heat waste computing method, specifically a kind of solar airconditioning heat waste computing method.
Background technology
Before utilizing sun power, the sun power of dispersion need to be put together.Concentrate the sun power obtaining to get being difficult for, therefore need to put forward high-octane utilization factor, yet heat waste is unavoidable, what we can only do is to greatest extent heat waste to be reduced to minimum.
Reducing heat waste is target, needs before this to calculate heat waste, calculates at present the method for heat waste and carries out reference calculating as provided numerical model, or provide efficiency calculation equation, and the account form of this class is all too complicated, is unsuitable for rapidly heat waste being judged.
Summary of the invention
The object of this invention is to provide a kind of solar airconditioning heat waste computing method, the method is simple and practical, can obtain fast result of calculation.
In order to achieve the above object, technical scheme of the present invention is: a kind of solar airconditioning heat waste computing method, is characterized in that comprising the following steps:
(1) adopt solar panel to gather solar energy, the angle of solar panel is identical with the flat plate collector angle of solar airconditioning, draws the gross energy Q1 of solar radiation in unit interval t;
(2), in first unit interval t, detect the temperature △ T1 that in vacuum tube, water temperature raises, in second unit interval t, detect the temperature △ T2 that in vacuum tube, water temperature raises ..., in n unit interval t, detect the temperature △ Tn that in vacuum tube, water temperature raises, n is positive integer;
(3) calculate in unit interval t the medial temperature △ T that in vacuum tube, water temperature raises, △ T=(△ T1+ △ T2+...+ △ Tn)/n;
(4) calculate in unit interval t the needed energy Q2 of water yield temperature rising △ T in vacuum tube;
(5) calculate (Q2-Q1)/Q1 * 100%, just obtain heat waste value.
In described step (2), △ Tn for to record under different environment temperatures.
