Intelligent enthalpy difference control energy-saving air conditioner and control method thereof

Abstract

The invention discloses an intelligent enthalpy difference control energy-saving air conditioner, which is provided with an indoor unit and an outdoor unit, wherein the indoor unit comprises an evaporator, an indoor fan and a compressor, and energy exchange is realized by an indoor and outer air enthalpy difference or in a control mode of combining outdoor air wet bulb temperature with indoor temperature and moisture variation. An outdoor cooling tower utilizes outdoor low-enthalpy air by the reinforced negative-pressure direct evaporating and cooling technology, and the energy exchange of indoor high-enthalpy air can be realized by combining the perfect combination of phase change refrigeration and mechanical refrigeration and by automatic switching. The indoor environment is humidified, cooled and dedusted by fully utilizing low-enthalpy water in the outdoor cooling tower or a cooler. Under the same condition, the condensation temperature of a refrigerant is lowered, and the condensation pressure is lowered. Under the same refrigeration working condition, the venting pressure of a compressor is lowered, the working current is reduced to obtain a bigger refrigeration amount, and an energy efficiency ratio is further improved. The air conditioner configuration is reduced, the service life of the air conditioner unit compressor is prolonged, and a purpose of saving energy and reducing consumption is achieved.

Description

Technical field [0001] The invention relates to a refrigeration technology, in particular to an energy-saving air conditioner with intelligent enthalpy difference control. The invention also relates to a control method of the intelligent enthalpy difference control energy-saving air conditioner. Background technique [0002] Global warming poses severe challenges to human survival and development. With the continuous growth of the global population and economic scale, the environmental problems caused by energy use and their incentives are constantly being recognized. A series of new concepts and policies such as "carbon footprint", "low carbon economy", "low carbon technology", "low carbon development", "low carbon lifestyle", "low carbon society", "low carbon city", "low carbon world" and so on To abandon the traditional growth model of the 20th century and directly apply the innovative technologies and mechanisms of the new century to achieve sustainable social development t...

AI Technical Summary

Problems solved by technology

[0003] Communication room, data room, automation room, base station and other computer rooms have a relatively large heat load. Even in winter, the air conditioner in the computer room is in the state of cooling and humidification, and because the computer room is fully enclosed, the external cold source cannot be used.

At present, there are many energy-saving technologies, such as: introducing cold outdoor air directly into the machine room or heat exchange. The exchange efficiency is low, but the humidity cannot be solved and both of them do not make full use of the outdoor low enthalpy air energy
