Embodiment Construction
[0020] Attached below figure 1 , 2 , 3 describe an embodiment of the present invention.
[0021] Intelligent dual cold source cooling and ventilation system: including a ventilation system and a refrigeration system. The outdoor fresh air enters the inlet of the refrigeration system after exchanging sensible heat with the indoor exhaust air in the ventilation system. The refrigeration system includes the primary refrigeration system 25 and the secondary refrigeration system. A two-stage refrigeration system 26, the two-stage refrigeration system 26 is composed of a constant flow refrigeration regulation system and a variable flow refrigeration regulation system, the constant flow refrigeration regulation system undertakes 50% of the cooling capacity of the entire system, and the variable flow refrigeration regulation system serves as Adjust the cooling capacity supplement when the outdoor working conditions change throughout the year, the outdoor fresh air through the primary...

The invention provides an intelligent double-cold-source cooling and ventilation system. According to the cooling and ventilation system, outdoor fresh air is subjected to heat exchange with indoor air required to be exhausted in a ventilation system and enters the inlet end of a refrigeration system; the refrigeration system comprises a primary refrigeration system and a secondary refrigeration system; the outdoor fresh air which passes through the primary refrigeration system enters the secondary refrigeration system; the outdoor fresh air which passes through the secondary refrigeration system is cooled and dehumidified and enters an air feeder through constant humidity heating; the outlet end of the air feeder is communicated with the indoor air; an air outlet of the secondary refrigeration system is provided with a temperature and humidity sensor and a temperature sensor; the temperature and humidity sensor and the temperature sensor feed the sensed temperature and humidity numerical value and the temperature numerical value back to a control system; and the control system identifies the numerical values and transmits a signal to the secondary refrigeration system. The design thought of subarea refining control is utilized, so that the air outlet stability of the cooling and ventilation system is guaranteed, the problem that extreme operating condition parameters are difficult to control in the prior art is solved, and normal production is effectively guaranteed.
Description
technical field [0001] The invention belongs to the technical field of cooling and ventilation of industrial workshops, and in particular relates to an intelligent cooling and ventilation system with dual cold sources, which is specially used for technical workshops with large heat load and high requirements on temperature and moisture content during year-round operation. Background technique [0002] With the continuous improvement of the industrial level, in many high-end machinery manufacturing or assembly plants or in food processing plants, the requirements for temperature and humidity are very high throughout the year. Under extreme working conditions (severe cold and high heat areas) to meet the temperature and humidity requirements required by the plant, especially the moisture content requirements, and can not make intelligent adjustments according to the user's temperature and humidity requirements, so it is necessary to improve.
