本文研究了用于空间制冷和供暖的天然气发动机驱动热泵（GHP）系统的现场冷却性能。性能数据是从安装在美国西南部六个军事设施的六个10吨GHP装置收集的。请注意，美国西南部的试验场地为空冷空间冷却系统提供了具有挑战性的运行条件。理论分析表明，与传统的燃气加热炉和用于空间冷却的电直接膨胀（DX）系统相比，GHP装置在空间加热和冷却方面的能效显著提高。 在本文中，在2007年冷却季节的3个月内，将GHP机组的现场测量冷却性能与理论效率进行了比较。一家独立实验室报告在实验室环境中测试GHP系统性能（Zaltash等人，2007年）。测试结果将在以GHP技术为主题的同一研讨会上公布，并将在同一ASHRAE交易卷中公布。比较了GHP在现场条件和实验室条件下的性能。本文还介绍了GHP系统在空间空调中的节能和成本节约潜力。 单位:I-PCitation:ASHRAE Transactions，第114卷，pt。2、盐湖城2008

This paper addresses the field cooling performance of a natural gas-engine-driven heat pump (GHP) system for space cooling and heating applications. Performance data were collected from six 10-ton GHP units installed at six military installations in the southwest United States. Note that the test sites in the southwest United States offer challenging operating conditions to air-cooled space cooling systems. Theoretical analysis showed significantly higher energy efficiency in space heating and cooling by GHP units compared to a conventional gas furnace for heating and electric direct expansion (DX) system for space cooling. In this paper, field measured cooling performance of the GHP units was compared to the theoretical efficiency during the 3 months of the 2007 cooling season. An independent laboratory reported  testing GHP system performance in a laboratory environment (Zaltash et al. 2007). The test results are presented in the same symposium session featuring GHP technology, and will be published in the same ASHRAE Transactions volume. GHP performance under field conditions and laboratory conditions were compared. This paper also presents the GHP system’s energy conservation and cost savings potential in space air conditioning.Units: I-P
