All-air air conditioning set containing all cold sources and heat sources and preparing cooling mediums or heating mediums simultaneously

Abstract

The invention relates to the technical field of air conditioning devices used in civil and industrial projects, in particular to an all-air air conditioning set containing all cold sources and heat sources and preparing cooling mediums or heating mediums simultaneously. The air conditioning set comprises a cooling or heating source unit, an externally-output cooling or heating medium unit, an all-air conditioning set and a cold or heat source unit, wherein the cooling or heating source unit prepares the cooling mediums or heating mediums and provides all cooling capacities or heating capacities for the air conditioning set to treat the air heat and humidity load, and no access to other external cold sources and heat sources is required; the externally-output cooling or heating medium unit can output the cooling mediums or heating mediums which treat freezing mediums as carriers toward the exterior, and the cooling mediums and heating mediums are not needed to be arranged additionally in other refrigeration zones or heating zones; the all-air conditioning set can conduct cooling and dehumidification treatment or heating and humidification treatment to fresh air and mixed air; the cold or heat source unit comprises a compressor, an expansion valve and a freezing medium circulation pipeline. According to the all-air air conditioning set, through the novel research and development of an equipment framework theory, the problems that in conventional air conditioning systems, the constitution is complex, a primary air system is independent, and a small local air conditioner cannot be arranged independently are solved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning units in civil and industrial projects, in particular to an all-air air-conditioning unit with all cold and heat sources and simultaneously preparing cold or heat medium. Background technique [0002] At present, the air-conditioning system solutions mainly include centralized (central air-conditioning), partially decentralized (multi-connected), and fully decentralized (split-type air-conditioning). [0003] The central air conditioner has a complex structure, including cold and heat sources, cold and hot water transmission and distribution systems, cooling towers, and air treatment terminals. Multi-connected air conditioners need to set up an independent fresh air system (need to be equipped with independent cold and heat sources). Split-type air conditioners have low energy efficiency ratio and no fresh air. And some local small spaces (kitchens, toilets, etc.) are not suitable for i...
