Low-temperature and low-humidity driven double-rotating-wheel dehumidification air conditioning system and air supply method thereof

Abstract

The invention discloses a low-temperature and low-humidity driven double-rotating-wheel dehumidification air conditioning system and an air supply method thereof. The low-temperature and low-humiditydriven double-rotating-wheel dehumidification air conditioning system comprises a double-rotating-wheel dehumidification air conditioning unit, a hot water circulating system, a cold water circulatingsystem and a sensible heat air conditioning terminal device. The double-rotating-wheel dehumidification air conditioning unit comprises a first dehumidification rotating wheel, a second dehumidification rotating wheel, a plate-type heat recovery device, an air pre-cooler, an air recooler, a main air heater, an auxiliary air heater, a treatment fan and a regeneration fan. The hot water circulatingsystem comprises a low-grade energy heat collector. The cold water circulating system comprises a water return well and further comprises a water supply well, a reservoir and a water quality treatment device which are sequentially connected. The air supply method of the low-temperature and low-humidity driven double-rotating-wheel dehumidification air conditioning system comprises an air supplying method under the summer working condition and an air supplying method under the winter working condition. The low-temperature and low-humidity driven double-rotating-wheel dehumidification air conditioning system is novel and reasonable in design, low in cost, low in energy consumption, high in refrigerating and heating efficiency, free of greenhouse effect, high in practicability and high in application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a low-temperature and low-humidity-driven dual-rotor dehumidification air-conditioning system and an air supply method thereof. Background technique [0002] On the one hand, energy is the material basis for promoting social and economic development, as well as the material basis for human survival and development. The sustained and rapid development of China's economy and society is inseparable from a strong energy guarantee. Building energy accounts for a large proportion of my country's energy consumption. With the development of society, people's requirements for space comfort are gradually increasing. The energy consumption of air conditioning has accounted for 50% to 60% of the energy consumption of the entire building. Building energy conservation has been recognized as the most potential and most direct and effective way of energy conservation. It is...
