Description
技术领域technical field

背景技术Background technique
设施农业打破了传统农业一直依赖自然环境条件生产的旧框框，采用人工环境调控技术与装备创造农作物生长的适宜环境，是实现集约高效可持续发展的现代农业生产方式，这就催生了农作物培养室空调技术的发展，对该领域的空调新技术提出了新课题。Facility agriculture has broken the old frame of traditional agriculture that has always relied on natural environmental conditions for production. It uses artificial environment control technology and equipment to create a suitable environment for crop growth. It is a modern agricultural production method that achieves intensive, efficient and sustainable development. This has given birth to the crop cultivation room. The development of air-conditioning technology has raised new issues for the new technology of air-conditioning in this field.
农作物生产周期短，生长周期内环境参数变化幅度大，特别是在高湿环境下的降温过程会产生大量凝露水，消耗空调系统的制冷能力，增大了生产成本。在生产环境与自然环境反差较大的季节，直接的新风换气也损失大量冷量或热量。目前生产技术中空调设施的能量消耗已经成为主要成本，一定程度上阻碍了设施农业技术的推广应用。The production cycle of crops is short, and the environmental parameters change greatly during the growth cycle. Especially in the cooling process in high humidity environment, a large amount of condensed water will be generated, which will consume the cooling capacity of the air conditioning system and increase the production cost. In seasons when the production environment is in contrast to the natural environment, direct fresh air ventilation also loses a lot of cooling or heat. At present, the energy consumption of air-conditioning facilities in production technology has become the main cost, which hinders the promotion and application of facility agriculture technology to a certain extent.
