作为建筑节能的对策可以列举以下三个方面:1.极力减少大型建筑物的能源需要量;2.采用高效率的设备,并使系统在最高效率点进行运转和管理;3.要尽可能利用废能源和自然能源。本文就空调部分的低温排热进行介绍,同时对发动机驱动热泵和吸收式冷冻机作概略说明。一、大型建筑物中可能利用的排热 As a countermeasure for building energy efficiency, the following three aspects can be cited: 1. To reduce the energy requirements of large buildings; 2. To adopt high-efficiency equipment and to operate and manage the system at the highest efficiency point; 3. To use as much as possible Waste energy and natural energy. This article introduces the low-temperature heat removal of the air-conditioning part, and outlines the engine-driven heat pump and the absorption refrigerator. I. Heat removal that may be used in large buildings
