Description
技术领域technical field
本发明涉及空调系统领域，更具体的说，是涉及一种多调节方式集成空调系统及其工作方法。The invention relates to the field of air-conditioning systems, and more specifically, relates to a multi-adjustment mode integrated air-conditioning system and a working method thereof.
背景技术Background technique
由于全球石化能源紧缺，使得天然气价格逐步升高，所以电能必将成为建筑采暖的常用热源。在所有的电采暖设备中，热泵系统是目前公认最节能环保的产品。由于辐射供暖对水温要求低，因此热泵作为热源搭配辐射末端是最佳的采暖系统。为了将辐射供暖设备性能最大化，除了冬季供暖以外，通过合理的设计和控制，在夏季制冷季还可以承担部分室内冷负荷，既可以提高采暖设备的性价比，也可以减小送风末端的结构尺寸，降低运行噪音，减少整套空调系统的设备成本。因此，辐射采暖末端已经摆脱传统概念上的采暖末端，升级为冬夏两用的调温末端。Due to the shortage of petrochemical energy in the world, the price of natural gas has gradually increased, so electric energy will surely become a common heat source for building heating. Among all the electric heating equipment, the heat pump system is currently recognized as the most energy-saving and environmentally friendly product. Since radiant heating has low water temperature requirements, a heat pump as a heat source with a radiant end is the best heating system. In order to maximize the performance of radiant heating equipment, in addition to heating in winter, through reasonable design and control, it can also bear part of the indoor cooling load in summer cooling season, which can not only improve the cost performance of heating equipment, but also reduce the structure of the air supply terminal size, reduce operating noise, and reduce the equipment cost of the entire air conditioning system. Therefore, the radiant heating end has got rid of the traditional concept of heating end, and has been upgraded to a dual-purpose temperature adjustment end for winter and summer.
为改善住宅建筑室内空气质量，我国住房城乡建设部于2018年12月发布了《住宅新风系统技术标准》的行业标准，编号为JGJ/T440-2018，要求自2019年5月1日起实施。该标准规定当住宅自然通风无法满足通风换气要求或不具备自然通风条件时，应该设置新风系统。而目前我国住宅的空调系统大多是基于满足采暖和制冷的要求设计的，很少考虑新风的需求，导致空调运行期间室内空气质量恶劣。为此，需要全面考虑采暖、制冷、新风多种需求的集成空调系统来满足社会需求。In order to improve the indoor air quality of residential buildings, the Ministry of Housing and Urban-Rural Development of my country issued the industry standard "Technical Standards for Residential Fresh Air System" in December 2018, numbered JGJ/T440-2018, which requires implementation from May 1, 2019. This standard stipulates that when the natural ventilation of the residence cannot meet the ventilation requirements or does not have the natural ventilation conditions, a fresh air system should be installed. At present, most residential air-conditioning systems in my country are designed to meet the requirements of heating and cooling, and rarely consider the demand for fresh air, resulting in poor indoor air quality during air-conditioning operation. To this end, an integrated air-conditioning system that fully considers the needs of heating, cooling, and fresh air is needed to meet social needs.
现有技术中，公开号为CN205037400U的实用新型专利提出了一种基于风冷热泵的供冷采暖系统。包括：风冷热泵、风机盘管系统和辐射板辐射系统。将风机盘管和辐射板辐射整合在一起，实现制冷和采暖，辐射板辐射用于采暖，风机盘管用于制冷，该专利地暖和风机盘管按季节独立运行且没有考虑新风系统，室内空气品质较差。本专利系统可以实现采暖和制冷运行时共用末端设备，提高系统经济性，并满足新风需求。In the prior art, the utility model patent whose publication number is CN205037400U proposes a cooling and heating system based on an air-cooled heat pump. Including: air cooled heat pump, fan coil system and radiant panel radiant system. The fan coil unit and radiant panel radiation are integrated to achieve cooling and heating. The radiant panel radiation is used for heating, and the fan coil unit is used for cooling. The patented floor heating and fan coil unit operate independently according to the season and do not consider the fresh air system. The quality is poor. The patented system can share terminal equipment during heating and cooling operation, improve system economy, and meet fresh air demand.
