Abstract

The invention belongs to the field of artificial environment control of constant-temperature and constant-humidity laboratories, phytotrons and the like and relates to a field phytotron temperature control system and temperature control method. The system comprises a constant-temperature water tank, a water chilling unit, a mold temperature controller, a first air heat exchanger and a second air heat exchanger; a water outlet of the constant-temperature water tank is communicated with a water inlet of the water chilling unit through a water pipe. By means of the design, the temperature of a phytotron can be accurately controlled, the crop growth climate environment under the natural condition can be simulated according to experiment requirements, and the problems of large air temperature control error, large indoor temperature uniformity error, large environment humidity change and high energy consumption of a phytotron are solved.

Description

technical field [0001] The invention relates to the field of artificial environment control such as a constant temperature and humidity laboratory and an artificial climate chamber, in particular to a temperature control system and a temperature control method for an artificial climate chamber in the field. Background technique [0002] With the development of agricultural scientific research and agricultural production technology, more and more artificial climate chambers appear. The artificial climate chamber is an experimental environment for simulating climate change in nature based on making full use of natural resources and comprehensively using knowledge of related disciplines such as biological science, information science, management science and automatic control science. According to the needs of different scientific research and agricultural production, the indoor temperature, humidity, light and CO2 concentration can be automatically controlled and adjusted to me...
