本文介绍了一种气体驱动的冷空气-水暖通空调系统，该系统使用干燥剂和50华氏度的冷冻水来产生40华氏度的空气。开发该系统的目的是为电动冷空气系统提供一种经济高效的替代方案。在峰值制冷需求、一次空气分配、风机需求（一次和二次）、系统峰值需求（夏季/冬季）、年电能使用（开/关峰）、天然气输入、年需求成本、年用电成本、年燃气成本、，年度总能源成本和系统第一成本。此外，还介绍了不同的公用费率结构对三种暖通空调系统能源成本的影响。 比较信息来自两项基于新泽西州北部一栋6层159000平方英尺办公楼的研究。关键词:天然气消耗、峰值负荷、电力消耗、电费、办公室、多层建筑、风扇、干燥剂、供暖、通风、空调、燃气、冰蓄冷、储能、能耗、比较、成本、美国引用:研讨会论文，佐治亚州亚特兰大，1990年

This paper describes a gas-energised cold air-water HVAC system that uses a desiccant plus 50 deg F chilled water to produce 40 deg F air. The system was developed to provide a cost-effective alternative to an electric-powered cold all-air system. The 40 deg F gas air-water system is compared with a 40 deg F all-air ice thermal storage system and a conventional 55 deg F all-air system in terms of peak refrigeration requirement, primary air distribution, fan demand (primary and secondary), system peak demand (summer/winter), annual electric energy use (on/off-peak), gas input, annual demand cost, annual electric use cost, annual gas cost, total annual energy cost, and system first cost. Also presented is the impact of various utility rate structures on the energy cost of the three HVAC systems being compared. The comparative information is drawn from two studies based on a six-story, 159,000 square ft office building in northern New Jersey.KEYWORDS: gas consumption, peak load, electricity consumption, tariffs, offices, multistorey buildings, fans, desiccants, heating, ventilation, air conditioning, gas fired, ice storage, energy storage, energy consumption, comparing, costs, USA.
