热泵作为实现显著节能的一种手段，几十年来吸引了大量的关注。然而，主要的挑战仍然是提高它们在寒冷气候中的性能。本文代表了一个更大的研究项目的第一步，实施非共沸制冷剂混合物，以提高住宅空气源热泵在寒冷气候下的性能。建立了一个详细的筛选热泵模型，并用于评估非共沸混合制冷剂的性能。选择了一组纯制冷剂，并研究了它们的潜在混合物。这些混合物的性能进行比较，以找到合适的非共沸制冷剂混合物的寒冷气候住宅应用。本文的主要目的是说明在传统热泵中应用环境友好的非共沸制冷剂混合物的可能性，以最小的变化的组件，以提高其性能。
Heat pumps, as a means of achieving significant energy reductions, have attracted a great deal of attention for decades. However, the main challenge remains improving their performance in cold climates. This paper represents the first step of a larger research project for the implementation of the zeotropic refrigerant mixtures in order to increase the performance of residential air-source heat pumps in cold climates. A detailed screening heat pump model is developed and used to assess the performance of zeotropic refrigerant mixtures. A group of pure refrigerants are selected and their potential mixtures are studied. The performance of these mixtures is compared in order to find suitable zeotropic refrigerant mixtures for cold climate residential applications. The main goal of this paper is to illustrate the possibility of applying environmentally friendly zeotropic refrigerant mixtures in conventional heat pumps, with minimal changes in the components, in order to improve their performance.
