Fresh air handling unit provided with cold/heat source without auxiliary heat exchange device and capable of outputting refrigerant/heat medium

Abstract

The invention discloses a fresh air handling unit provided with a cold / heat source without an auxiliary heat exchange device and capable of outputting a refrigerant / heat medium. The fresh air handling unit comprises a cold / heat source unit without the auxiliary heat exchange device, a fresh air heat-humidity treatment unit and a refrigerant / heat medium output unit. The cold / heat source unit without the auxiliary heat exchange device dissipates heat or heats through exhaust air or fresh air and can provide all cold / heat energy for air heat and humidity load treatment of the unit without externally arranging auxiliary heat dissipation or heating devices. The fresh air heat-humidity treatment unit can cool, dehumidify, heat and humidify the fresh air. The refrigerant / heat medium output unit can output the refrigerant / heat medium to provide cold / heat energy to other devices. By means of the fresh air handling unit, centralized cold / heat source equipment, externally-arranged heat dissipation or heating devices, transportation and distribution systems among the cold / heat source and the air conditioning unit or other air treatment terminals can be reduced or omitted, meanwhile transportation and distribution energy consumption of a fresh air system is saved, the problem that cold energy / heat energy distribution and adjustment among the centralized cold / heat source and air conditioner partitions are difficult is solved, and energy is saved remarkably.

Description

technical field [0001] The invention relates to the technical field of air-conditioning units in civil and industrial projects, in particular to a fresh air unit with its own cold and heat source and no auxiliary heat exchange device and externally transporting cold and heat media. Background technique [0002] Now the traditional energy we use is gradually becoming exhausted, saving energy and reducing pollution are the primary issues facing the world. Now our country's energy use policy is to develop and save simultaneously, saving the first place. Accompanying the rapid development of the national economy is the improvement of people's living standards. The application of central environmental protection air conditioners is becoming more and more popular, which has greatly improved people's production and living environment. The accompanying problem of energy consumption is also gradually highlighted. Therefore, no matter for the developers of central air-conditioning or ...

Problems solved by technology

[0008] The present invention aims to solve the above-mentioned two major problems, one is to solve the problem of high energy consumption of traditional air-conditioning systems (mainly central air-conditioning systems), and the other is to solve the problems of performance mechanism defects of traditional air-conditioning, including excessive occupation of building area, single function, and inability to Cooling / heating, multiple equipment links lead to inherent problems such as long construction period and high cost of complex management. According to the theory of equipment structure, a new type of fresh air with its own cold and heat source and no auxiliary heat exchange device is newly developed and designed. Unit, the technical scheme that the present invention adopts for solving the above-mentioned technical problems is as follows:
