Claims (4)
P = F(K • (Tв - Tн) - Q),
где F - суммарная площадь ограждения теплицы, м2;
К - коэффициент теплопотерь, кВт/м2 • oC;
Tв - оптимальная температура воздуха в теплице, определяемая, например, по критерию продуктивности, прибыли или удельной энергоемкости, oC;
Tн - температура наружного воздуха, oC;
Q - плотность потока солнечной радиации, кВт/м2.1. The system of automatic temperature control in the greenhouse, including a heating system and an automatic control device, characterized in that the heaters are divided into two autonomous groups, the powers of which are in a ratio of 4 - 5: 1, and the power of the first group is regulated depending on disturbances and found by the following formula:
P = F (K • (T in - T n ) - Q),
where F is the total area of the fence of the greenhouse, m 2 ;
K is the heat loss coefficient, kW / m 2 • o C;
T in - the optimal air temperature in the greenhouse, determined, for example, by the criterion of productivity, profit or specific energy consumption, o C;
T n - outdoor temperature, o C;
Q is the flux density of solar radiation, kW / m 2 .
