Greenhouse temperature control system

Abstract

The invention relates to the technical field of agriculture, and in particular to a greenhouse temperature control system. Compared with the prior art, the greenhouse temperature control system comprises a cold and hot exchange board, a cold and hot water dual-purpose heat preservation storage box, a cold and hot air circulation distributing machine and an air supply and exhaust system, wherein the unique cold and hot exchange board and the cold and hot water dual-purpose heat preservation storage box are adopted; cold energy or heat is transmitted to the greenhouse by the cold and hot water dual-purpose heat preservation storage box through the cold and hot air circulation distributing machine and the air supply and exhaust system, so that indoor temperature of the greenhouse or other places can be freely regulated, and can be rapidly reduced or raised in a short time, and the primary investment cost and the running cost for a long time of users can be reduced; a temperature control device system which is efficient, energy-saving and environmentally friendly can be realized, the ideal temperature needed by the users can be rapidly reached, and the uniform ideal constant temperature effect can be kept for a long time. The greenhouse temperature control system has the characteristics of being low in installation cost, low in use cost, economic and practical, saving the energy, protecting the environment and having good market prospect and the like.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a greenhouse temperature control system. Background technique [0002] In agricultural production, many of them are cultivated and planted in greenhouses. Cultivation and planting in greenhouses require suitable temperature and sunlight, especially for special plants, such as Phalaenopsis. Phalaenopsis is a tropical plant. The temperature should be maintained between 15-34°C, the appropriate temperature is as follows: 26-27°C for the growth stage, 19-21°C for the flowering stage, in order to get more flower stalks, the temperature can be maintained at 18-20°C, a total of 4 ~8 weeks, when the light is insufficient or the daily temperature is too high, it should be maintained at 18°C ​​to strengthen the flowering (induced flower buds). Vegetative growth loses flower buds, so temperature control is most important. [0003] In the prior art, the temperature control of the gre...

Problems solved by technology

[0003] In the prior art, the temperature control of the greenhouse mainly adopts the cooling technology of the water curtain wall, but the cooling technology of the water curtain wall is only suitable for lowering the temperature in high temperature seasons to play an auxiliary role, and it cannot make the indoor temperature rise and fall freely and cool down at any time. And the effect of environmental dryness and humidity is not ideal, especially it cannot meet the special low temperature requirements of plants

There are also some that use central air conditioners or household air conditioners to directly cool down. This method also has many shortcomings, such as high investment costs, high operating costs and energy consumption, and slow or uneven indoor temperature.

There are also some that combine coal and boilers or use electric boilers and diesel heating machines for heating, but this mode is similar to the above-mentioned air-conditioning and water curtain wall cooling technology, but it can only be used for heating in winter, and There are environmental protection and risk issues such as high energy consumption and environmental pollution. Therefore, in the field of plant greenhouse cultivation, there is an urgent need for a greenhouse temperature control system that can meet various temperature requirements.
