Embodiment Construction

[0126] Since the present invention discloses a fresh air-conditioning overall system device and the design matching method of each subsystem, in order to clearly explain the system configuration and design calculation method, the specific structure, component composition, and function are discussed in detail in the content of the invention Relationships, matching calculations, and other aspects are described, which is equivalent to a principled and comprehensive implementation description, which will not be repeated here. The following is a specific design example to describe in detail the calculation process and energy saving comparison under the primary return air mixed air mode in summer.

[0127] calculation process

[0128] It is known that the local atmospheric pressure is 101325Pa, the indoor cooling load Q=19.80kW, the humidity load W=0.0044kg / s, the outdoor air state temperature Relative humidity indoor comfort temperature Relative humidity Supply air tempera...

Abstract

The invention relates to the field of heating ventilation air conditioners, in particular to an improved air treatment method and a fresh air conditioner device. The invention improves the problems of traditional fresh air treatment and air conditioners and particularly emphasizes that a plate-type air-air heat exchanger and indirect water evaporative cooling are used for recycling energy of sensible heat and latent heat in air exhaust in the fresh air treatment process of damp and hot regions in summer and condensed water is directly evaporated on an evaporator to improve the working condition of a compressor. Under the condition of quantificationally supplying outdoor fresh air, the energy efficiency ratio of the fresh air conditioner is increased, the thermal pollution, damp pollution and noise pollution of the fresh air conditioner to environments are reduced, the indoor air quality is improved, and meanwhile, the fresh air conditioner provides the manufacture, installation and using convenience for a local region all-air central air conditioner. The fresh air conditioner provided by the invention and a design and manufacture method of the fresh air conditioner are applicable throughout the year in various regions, particularly in the damp and hot regions; and the fresh air system provides controlled, comfortable and healthy air environments for indoor activity space of people and air conditioner environments for technology for processing, storage and the like.

Description

technical field [0001] The invention relates to the field of HVAC, in particular to an improved air treatment method and a fresh air air conditioning device, especially emphasizing the use of plate air-air heat exchangers and indirect water evaporative cooling in the exhaust air during the fresh air treatment process in hot and humid areas in summer. Heat and latent heat for energy recovery. Background technique [0002] The main purpose of the air conditioning system is to provide a controllable, comfortable and healthy air environment for people's indoor activity space or provide specific air environment conditions for storage, processing, equipment operation and other activities. The main control indicators of air conditioning include air quality, air temperature, air humidity and wind speed. [0003] The more natural and effective way to control air quality is to use outdoor fresh air to replace or dilute indoor air, that is, to inhale outdoor fresh air and discharge in...
