Description
Technical Field

Background
The regulation and control process of the indoor hot and wet environment of the building comprises two aspects of regulation and control of indoor temperature and humidity, and a conventional air conditioning system generally utilizes a single cold source to simultaneously realize the regulation and control of the temperature and the humidity, so that energy utilization grade loss can be brought, and the effective regulation and control of the indoor hot and wet environment of the building can not be realized due to the gradual change of indoor sensible heat load and wet load. Air conditioning systems usually undertake a plurality of environment construction and control tasks such as meeting building temperature, humidity, cleanliness factor, fresh air supply and the like, and conventional air conditioning systems adopt a mode of combining to meet requirements according to different requirements, so that conditions such as temperature and humidity coupling, temperature and humidity control and fresh air supply coupling, fresh air and cleanliness factor control coupling and the like may exist. Starting from basic environment control requirements, various environment construction control requirements are independently met, corresponding key equipment and a regulation and control method are configured, the method has important significance for better meeting the construction environment construction requirements and realizing various construction processes more efficiently, the system is also favorable for realizing better operation regulation and control, and the situation that the environment control targets cannot be simultaneously guaranteed due to coupling influence among different control targets is avoided.
As a novel air conditioning system form, the temperature and humidity independent control air conditioning system respectively adjusts the indoor temperature and humidity by different means: the humidity is adjusted by supplying dry air to bear the humidity load in the room, and the temperature in the room is adjusted by high-temperature cold water or refrigerant. The air conditioning mode can better complete the task of adjusting the indoor temperature and humidity, and can realize good energy-saving effect while effectively realizing the regulation and control of the building hot and humid environment. In the temperature and humidity independent control air conditioning system, the temperature of high-temperature cold water or a refrigerant required by temperature control is generally about 16-18 ℃, at the moment, the evaporation temperature of a cold source required by a compression refrigeration mode can be far higher than that corresponding to a conventional condensation dehumidification mode, and the energy efficiency of the refrigeration system can be greatly improved. At present, various high-temperature water chilling units are available, and therefore the independent temperature and humidity control air conditioning system is well popularized and applied to various buildings.
Compared with the conventional overground buildings, the underground buildings have higher requirements on environmental parameters such as temperature and humidity, cleanliness, fresh air supply and the like, the load composition and the source of the underground buildings are obviously different from those of the overground buildings, the underground buildings with some functions have the characteristic of high sensible heat load, and meanwhile, the underground enclosure structure has the characteristics of higher dehumidification requirement and the like because the moisture load caused by moisture dissipation of the underground enclosure structure is not negligible.
