Embodiment 1

[0030] Example 1: Single-parameter control (temperature control, mainly applicable to the environmental control of building spaces with temperature as the main goal, such as ordinary offices and main workshops of hydropower stations)

[0031] Single parameter control embodiment 1 selects indoor temperature (including acceptable temperature Tn, Tn=22.2+0.003(t out ) 2 , t out The indoor and outdoor ambient temperature detection value is compared with the set value, and the form and method of energy utilization are determined by the difference between the indoor and outdoor temperature detection value and the set value.

[0032] In this embodiment, the influence of outdoor rainfall intensity (1ml / h) is also taken into account by the method of controlling signal correction, so as to prevent indoor overheating / overcooling. The automation control strategy corresponding to embodiment 1 is as follows figure 2 shown.

[0033] The specific control method is:

[0034] 1) Determi...

Embodiment 2

[0042] Example 2: Dual parameter control (temperature and CO 2 Concentration control, mainly applicable to the environmental control of building spaces where temperature and indoor air quality are the main objectives, such as smoking rooms and kitchens)

[0043] This embodiment selects indoor temperature (including acceptable temperature Tn, Tn=22.2+0.003(t out ) 2 , same as Example 1) and CO reflecting indoor air quality 2 Concentration (take 1000ppm as the allowable upper limit of concentration) as the control object, compare the measured value of the two parameters with the set value to determine the specific form and method of energy utilization, the two parameters are based on indoor temperature - indoor CO 2 The sequence of concentrations is controlled step by step. Embodiment 2 also takes into account the influence of outdoor rainfall intensity (1ml / h) through the method of control signal correction. This correction control signal can be used to adjust the ener...

Abstract

The invention discloses an environmental control method realizing energy stepped utilization by utilizing automatic opening and closing of windows. In the method, an air conditioner is arranged in a room; a motor is arranged on an external window of the room; the motor drives the external window to be opened and closed; a temperature sensor and a CO2 concentration detection sensor are arranged in the room; an outdoor temperature and rainfall capacity detection sensor is arranged outside the room; the temperature sensor, the CO2 concentration detection sensor and the rainfall capacity detection sensor are respectively connected with a digital quantity acquisition module; and the air conditioner, the digital quantity acquisition module and the motor are respectively connected with a digital quantity control module, thus achieving the environmental control effect of the architectural space, simultaneously lowering the environmental control energy consumption, reflecting the low-carbon economy concept, combining the automation technique and the environment control, and providing guarantee to accurately control the thermal comfort of the architectural space.

Description

technical field [0001] The present invention relates to an environment control of building space, in particular to an environment control method using automatic opening and closing of windows to realize cascade utilization of energy. Background technique [0002] While traditional air-conditioning technology ensures the indoor air environment and process environment, it also consumes a large amount of high-grade energy, and causes serious problems such as poor indoor air quality and sick building syndrome. Compared with this, the traditional ventilation technology consumes less energy, but the accuracy of environmental control is poor, and it is difficult to meet the comfort requirements. How to reduce the energy consumption of environmental control and rationally utilize renewable energy while satisfying and achieving the effect of indoor air environment control has become a key issue of widespread concern in the field of HVAC energy-saving and emission-reduction technologi...
