摘要

如今,在工业、公共和住宅小房间的空调和供暖系统中,空调分体式热泵的使用越来越普遍。然而,空气分体式空调的热泵是能源密集型设备,因此,需要提高其能源效率。在空调器热泵模式下,降低制冷机的能耗是很重要的,这可以用一种现代的热力学方法来实现。用能分析允许建立系统的最大热力学能力,确定其中的用能损失,并提出改进其某些元素的建议。本文采用作者自行研制的空调器一级蒸汽压缩机氟利昂热泵运行分析方法。由此,建立了“三菱电机”供热容量为3200w的空调式热泵用能输出输入比(OIR)确定的通用依赖关系,使其运行参数选择具有最大用能输出输入比(OIR)成为可能。所描述的获得这种普遍依赖关系的算法可用于任何企业和任何供热能力的热泵空气分体式空调。

Universal dependence for determining exergetic output-input ratio of air split-conditioner heat pump
Today, in air conditioning and heating systems for small rooms of industrial, public, and residential buildings, the use of heat pumps of air split-conditioners is becoming more common. However, heat pumps of air split-conditioners are energy-intensive equipment, and, therefore, the need to increase their energy efficiency arises. It is important to reduce energy consumption during the refrigeration machines operating in the mode of heat pump in air split-conditioners, which is possible using a modern method of thermodynamics — an exergetic one. Exergetic analysis allows for establishing the maximum thermodynamic capabilities of the system, determining the losses of exergy in it, and substantiating recommendations for improving some of its elements. The exergetic method of analysis of the operation of one-stage steam-compressor freon heat pumps of air split-conditioners developed by the authors is used in this article. As a result, the universal dependence for determining the exergetic output-input ratio (OIR) for the air split-conditioner heat pump by "Mitsubishi Electric" with a heating capacity of 3200 W has been established, which makes it possible to select the parameters of its operation with the maximum exergetic OIR. The described algorithm for obtaining such a universal dependence can be used for heat pump air split-conditioner of any firm and any heating capacity.
