Thermodynamic perfectibility based analysis of

energy-efficiency standards for air conditioning products in China

1. Introduction

With an acceleration of urbanization and a rise in living standards in China, air conditioning products are widely used. Air conditioning products in China include room air conditioners, variable speed room air conditioners, unity air conditioners, multi-connected air conditioners (heat pump) units and chilled water air conditioning systems. China is the world’s largest producer and a big exporter of room air conditioners. And in recent years, there has been an increase in the use of water chillers in public buildings. According to incomplete statistics, the shipment of all types of water chillers in public buildings increased by 26.5% in 2007, compared with that in 2006 [1]. A preliminary estimate indicates that the energy consumption of all air conditioning products amounted for about 20% of the total building energy consumption [2]. Therefore, the air conditioning products play a crucial role in the energy saving and emission reduction of construction industry.

In order to reduce the energy consumption for the air conditioning products, China has enforced many energy efficiency standards for them including GB12021.3-2010 [3], GB21455-2008 [4], GB19576-2004 [5], GB19577-2004 [6], and GB 21454-2008 [7]. Among these standards there are different types of performance evaluation indexes for different types of air conditioning products, such as the energy efficiency ratio (EER), the coefficient of performance (COP), the seasonal energy efficiency ratio (SEER) and the integrated part load value (IPLV) and so on. These performance evaluation indexes have different test methods and calculation formula, which makes it difficult to evaluate the energy efficiency of different air conditioning products by using these evaluation indexes. To compare the energy efficiency of different air conditioning products, it is necessary to establish a public energy efficiency platform. This paper first presents that thermodynamic perfectibility is considered as performance evaluation indexes to evaluate different air conditioning products. Based on thermodynamic perfectibility, this article makes the compatible analysis of the energy efficiency standards for different air conditioning products. 2. Basic types of air conditioning systems

The thermodynamic power cycle of the air conditioning systems is one whose heat is supplied from a high-temperature source to the engine and its low temperature source is air passed through air conditioning systems. The high temperature source is outdoor air or water. According to the type of high temperature sources, air conditioning systems can be classified into two categories: air-source and
