Abstract

The invention relates to a two-channel return air air-conditioning case. The two-channel return air air-conditioning case comprises a return fan section, an air exhaust section, a fresh return air mixing section, a filter section A, a surface cooling section, a heating section, a humidifying section, a forced draft fan section, a filter section B and a control air valve. A return air port is formed above the return fan section, the return fan section is connected with the air exhaust section, an air exhaust port is formed above the air exhaust section, the upper section the air exhaust section is connected with the fresh return air mixing section, a fresh air port is formed above the fresh return air mixing section, the fresh return air mixing section is connected with the filter section A, the filter section A is connected with the surface cooling section, a chilled water connector is arranged above the surface cooling section,, and the surface cooling section is connected with the heating section. The lower section of the air exhaust section is connected with the filter section B through a partition pipe, the filter section B is connected with the control air valve, and the control air valve is connected with the heating section. The heating section is connected with the humidifying section, and the humidifying section is connected with the forced draft fan section. The two-channel return air air-conditioning case improves the energy-saving potential of an air-conditioning system and meets the energy-saving and emission-reducing requirements.

Description

technical field

[0001] The invention relates to a technical constant temperature and humidity air conditioning system for cigarettes. Background technique

[0002] The traditional constant temperature and humidity air-conditioning box usually uses chilled water to cool the air through the surface cooler in summer. Since the technological air conditioners in cigarette factories have dual requirements for temperature and humidity, in the process of cooling the air by the surface cooler, in order to achieve air Humidity requirements will produce overcooling to achieve the purpose of dehumidification, and the cooling capacity of the overcooled part needs to be heated by steam to meet the air temperature and humidity requirements.

[0003] The reheating phenomenon produced by the above traditional air cooling method will waste a lot of energy, and need to add a large amount of steam to overcome the excessive cooling capacity, which does not meet the requirements of energy saving ...
