Problems solved by technology

If refrigerant is used as the refrigerant, although there is no danger of freezing, the temperature of the wall surface of the cooling coil will be lower than 0°C, and the surface will be frosted. After a long time, the air passage will be blocked and the system will not be able to operate.
At the same time, the temperature of the cold source decreases, and the energy efficiency ratio of the air conditioning system also decreases

Embodiment

[0040] Example: see figure 1 In the air cooling and dehumidification method of the plant factory of this embodiment, two sets of heat exchangers with a common air duct 3 are arranged in the plant factory, and the two sets of heat exchangers are connected in series in the common air duct before and after.

[0041] In the two sets of heat exchangers, the first heat exchanger is set as the heating coil 1, which first contacts the air to heat the air; the second heat exchanger is set as the cooling coil 2, and the outlet air of the heating coil Perform cooling and dehumidification.

[0042] In practical applications, the heat source of the heating coil 1 is the condensation heat of the refrigeration unit in the plant factory or the heat dissipation of the artificial light source.

[0043] For the schematic diagram of the cooling and dehumidifying method of the present invention, see figure 1 , The change of air condition in the cooling and dehumidifying air-conditioning system of the p...

Abstract

The invention discloses an air cooling-dehumidifying method for a plant factory. Two groups of heat exchangers sharing a common air flow channel are arranged in the plant factory; the two groups of heat exchangers are connected in series from front to back in the common air flow channel; for the two groups of heat exchangers, the first heat exchanger is set to be a heating coil which is firstly contacted with air so as to heat the air and the second heat exchanger is set to be a cooling coil which cools and dehumidifies the air at the outlet of the heating coil; and the heat source of the heating coil is the condensation heat of a refrigerating unit in the plant factory or the radiation heat of an artificial light source. The invention solves the difficulties that the existing dehumidifying equipment is poor in dehumidification effect or even can not achieve humidification in the environment with low temperature and high humidity.

Description

Technical field: [0001] The invention relates to an air cooling and dehumidifying method and a cooling and dehumidifying air conditioning system for a plant factory, in particular to a method for air cooling and dehumidifying in a closed space under a low temperature and high humidity environment, and an air conditioning system used to realize the method. Background technique: [0002] "Plant factory" refers to a plant cultivation system that uses artificial environment control and computerized production management for year round plant cultivation. Plants are planted in a confined space like a factory building. The temperature, humidity, carbon dioxide, oxygen, fertilizer, nutrients, light, etc. required for their growth are controlled, and they are no longer affected by the external climate and environment. They are annualized, refined, Features such as homogenization and high yield. [0003] According to the population report published by the United Nations, the global populati...
