Designing an HVAC System for Indoor Agriculture Green room

图片
According to the basic process from production to table, modern agriculture can be divided into six stages: production, processing, storage, transportation, sales, consumption and so on. The first two stages are the modern agricultural stage, and the last four stages are the logistics stage (including cold chain materials). The modern agriculture stage can be divided into two stages of production and processing according to its characteristics. The production stage can be divided into three parts. This article focuses on the HVAC equipment and HVAC technology used in the production stage. The three blocks of the production phase include: 1. Breeding industry. Such as fish, shrimp and other aquaculture farming in water according to modern agricultural methods. 2. Planting industry. Such as edible fungi, greenhouse vegetables, Chinese medicinal materials, and other crops grown indoors according to modern agricultural methods. 3. Animal husbandry. Animal husbandry such as rais...

Dry chillers, flooded chillers, falling film chillers difference. Frequently, customers ask about dry chillers, flooded chillers, falling film chillers, and what are the differences? Today I will talk about the main differences between these three chillers and their advantages and disadvantages to help you understand them. In fact, the three different names are mainly because their evaporators are not used, and their main difference is also their evaporators. [caption id="attachment_944" align="alignright" width="300"] Dry chillers, flooded chillers, falling film chillers difference.[/caption] The dry chiller is the chiller that we usually see. The refrigerant of the evaporator passes through the heat exchange tube, and the cold water runs outside the heat exchange tube. The advantage of the dry chiller is that the price is relatively cheap, the structure is simple, it is easy to return oil, and the control is also Relatively simple, the injection vo...

Water requirements for chilled water quality

Water requirements for chilled water quality When we talk about how to maintain the chiller, we always pay attention to the chiller system structure itself, but we do not talk about this topic from some external factors. Today, the editor will talk about the maintenance of the chiller from the perspective of frozen water. If the cooling performance of a chiller is to be kept in a stable state, strict requirements must be imposed on the source of chilled water. Otherwise, a variety of sudden failures will occur during the use of the equipment. Therefore, the use of chillers must be accompanied by the use of high-quality frozen water sources, so as to reduce consumption and use costs, which is conducive to the long-term safe use of chillers. So what are the chiller requirements for chilled water? [caption id="attachment_782" align="alignright" width="218"] Water requirements for chilled water quality[/caption] pH Any chilled water with too high al...
