Hot-blast air type warming, constant-temperature and constant-humidity system

Abstract

The invention relates to the technical field of temperature and humidity control, in particular to a hot-blast air type warming, constant-temperature and constant-humidity system which is used for adjusting the temperature and humidity in a greenhouse and comprises an indoor unit; the indoor unit comprises a machine shell with air flowing between the upper end face and the lower end face; a first-stage evaporator and a first-stage condenser are sequentially arranged in the machine shell from bottom to top; the first-stage evaporator and the first-stage condenser communicate in the same heat pump loop; a heat transfer working medium is arranged in the heat pump loop; a centrifugal fan is arranged below the first-stage evaporator or above the first-stage condenser; and an outdoor unit for heating the interior of the greenhouse is arranged outdoors. The hot-blast air type warming, constant-temperature and constant-humidity system has the advantages of dehumidifying the interior of the greenhouse, facilitating photosynthesis of crops, and ensuring development of crops.

Description

technical field [0001] The present application relates to the technical field of temperature and humidity control, in particular to a hot air heating constant temperature and humidity system. Background technique [0002] At present, in order to solve the needs of people's lives, people often plant some crops in greenhouses, especially when the outdoor temperature is low in winter. [0003] In winter, the temperature outside the greenhouse is low, and the crops inside the greenhouse need a higher temperature. At this time, it is necessary to increase the temperature of the greenhouse, but at the same time, it will increase the humidity of the air in the greenhouse. In winter, in order to avoid The cold air outside enters the room, and the moisture cannot be discharged outside. If the humidity in the air remains too high for a long time, it will directly affect the photosynthesis of crops, and eventually affect the development of crops. Contents of the invention [0004] I...

[0003] In winter, the temperature outside the greenhouse is low, and the crops inside the greenhouse need a higher temperature. At this time, it is necessary to increase the temperature of the greenhouse, but at the same time, it will increase the humidity of the air in the greenhouse. In winter, in order to avoid The cold air outside enters the room, and the moisture cannot be discharged outside. If the humidity in the air is kept too high for a long time, it will directly affect the photosynthesis of crops, and eventually affect the development of crops.
