✔ 最佳答案
Watt is commonly used in thermal measurement products. Air (humidity) the quality of
Greenhouse addition to the degree of temperature rise into the greenhouse by the incident in light of the impact of greenhouse ventilation of the situation on the ground and so on crop growth are directly related. When the temperature has been rising, the heat of its foreign (including conduction, convection and radiation) with the increase, when the heat of the sun and heat balance of incident, they reached the limit warming.
Turning to temperature and humidity control, energy and quality can not be separated from the two major conservation law; talking about temperature and humidity control, can not be separated from air and water. Containing water vapor the air as moist air (moist air); wet air on the various relations in the humid air thermodynamics (Psychrometrics) are detailed in the study. The theme of this chapter is introduced in the humid air of various thermal nature, its application and related microcomputer software. Finally brief province's temperature and humidity weather conditions.
Second, energy conservation and quality
Through the appropriate software and hardware to the indoor temperature of, the environment outside the parameters, and in accordance with the parameters set to calculate the precise drivers of all types of settings, Piruo: boiler or heater temperature settings, fan of Open to the number and the number of openings the size of the windows, spray nozzle devices such as the use of volume and flow, is the so-called temperature and humidity control. Precision and no contradiction between the control can ensure that crops in the appropriate environment for the growth.

Temperature and humidity control system is good or bad depends on the system design,
2008-09-12 16:23:59 補充:
systems design involves many, all in terms of quality and energy conservation are beginning here refers to the quality of water,
2008-09-12 16:25:43 補充:
nutrients, oxygen, carbon dioxide, and so on. The quality of greenhouse environment can be conserved under a simple note -
Access to the system of quality systems in the left = + stored in the quality of the crop
2008-09-12 16:26:01 補充:
Add the physical quality (BioMass)
Energy through solar radiation, thermal radiation, heat conduction, convection heat, condensation, or into the greenhouse with a fluid into the greenhouse or through the heater,
2008-09-12 16:26:21 補充:
heat exchangers, such as auxiliary lighting in the greenhouse produce. By reflecting solar energy is also light, heat radiation, heat conduction, convection heat, evaporation, air conditioning
