New energy air-conditioning method and system for extremely low energy consumption houses of new rural construction

Abstract

The invention relates to a new energy air-conditioning method and a new energy air-conditioning system for extremely low energy consumption houses of new rural construction. Aiming at actual air-conditioner requirements and economy bearing capabilities of new rural construction users and increasing national macro energy tension, air-conditioner design target parameters are radically adjusted, and thermal performance design of buildings are improved; the system is designed according to the basic design principles of greatly reducing load demand and furthest utilizing natural energy sources such as solar energy, geothermal energy, air energy and the like; thermal air-condition independent humidification, low temperature radiation and water loop heat pump technology are comprehensively adopted; when cold is supplied in summer, ground source water flows through a water loop heat pump evaporator, an indoor radiation tail end, a fresh air unit surface cooler and a ground source heat pump condenser; the solar energy and the water loop heat pump condenser work together for regeneration of independent humidification components; and when heat is supplied in winter, the ultralow temperature solar energy and the ground source heat pump are combined to provide heated water of 15 to 25 DEG C. Compared with the traditional urban air-conditioning system, the power consumption of the system is only about 10 to 25 percent; and indoor comfortableness is effectively promoted, and initial investment is greatly reduced.

Description

technical field [0001] The invention relates to a new energy air-conditioning method and system that can be used for building extremely low-energy houses in new countryside, and belongs to the technical field of new energy and air conditioning. Background technique [0002] Air-conditioning cooling and heating energy consumption in commercial and civil buildings accounts for an increasing proportion of building energy consumption. With the implementation of new rural construction and urbanization development strategies, air-conditioning energy consumption is rigid in the overall energy demand of society. However, compared with the early 1980s, the potential scale of the expanded urban residents will increase by more than 4 to 5 times. If the air-conditioning and heating methods adopt the same level as that of urban residents, China's year-round air-conditioning The overall level of energy consumption will likely double the existing energy consumption of the whole society, wh...
