Title: Analysis of Environmentally Friendly Refrigerant Options for Window Air Conditioners

Abstract

This paper presents a technical assessment of environmentally friendly refrigerants as alternatives to R410A for window air conditioners. The alternative refrigerants that are studied for its replacement include R32, a mixture of R32/R125 with 90%/10% molar concentration, R600a, R290, R1234yf, R1234ze and R134a. Baseline experiments were performed on a window unit charged with R410A. The heat pump design model (HPDM) was modified and calibrated with the baseline data and was used to evaluate the comparative performance of the WAC with alternative refrigerants. The paper discusses the advantages and disadvantages of each refrigerants and their suitability for window air conditioners. Among all the refrigerants studied, R32 offers the best efficiency and the lowest Global Warming Potential (GWP), and hence its use will result in the overall environmental friendliness.

Assessment of Environmentally Friendly Refrigerants for Window Air Conditioners

Conference Bansal, Pradeep ; Shen, Bo

This paper presents technical assessment of environmentally friendly refrigerants for window air conditioners that currently use refrigerant R410A for residential and commercial applications. The alternative refrigerants that are studied for its replacement include R32, R600a, R290, R1234yf, R1234ze and a mixture of R32 (90% molar concentration) and R125 (10% molar concentration). Baseline experiments were performed on a window unit charged with R410A. The ORNL Heat Pump Design Model was calibrated with the baseline data and was used to assess the comparative performance of the WAC with alternative refrigerants.

Flow condensation heat transfer performance of natural and emerging synthetic refrigerants

Journal Article Morrow, Jordan A. ; Huber, Ryan A. ; Nawaz, Kashif ; ... - International Journal of Refrigeration

There is great interest in predicting flow condensation heat transfer for lower global warming potential (GWP) fluids. This paper analyzes the efficacy of common flow condensation correlations developed for particular fluids in order to identify their suitability to predict heat transfer performance of low GWP fluids. Condensation heat transfer data were extracted from the literature, including 19 papers and 1,473 data points for natural refrigerants [i.e., ammonia (R717), CO₂ (R744), propane (R290), isobutane (R600a)] and 35 papers and 5,030 data points for synthetic refrigerants [i.e., R12, R1234yf, R1234ze(E), R1234ze(Z), R22, R32, R41, R123, R125, R134a, R142b, R152a, R161, R404A, R410A,more »« less

Extending ORNL HPDM Capabilities for Design and Optimization of New Refrigerant Blends – FY18 2nd Quarter Milestone Report: Improve HPDM to Adopt New Refrigerant Properties and Correlations

Technical Report Shen, Bo

We added new refrigerant properties of HFO blends to the ORNL HPDM, including R-22 alternatives, i.e. N20b, DR3, ARM20a, ARM20b, R444B, DR93; R-410A alternatives, i.e. R447A, R447B, R452B, R32, ARM71a; R-134a alternatives, i.e. R1234yf and R1234ze. It can also simulate natural refrigerants, e.g. propane (R290), Isobutane (R600a), CO2 and Ammonia. In addition, latest heat transfer and pressure drop correlations best for low GWP refrigerants were integrated to the equipment design and simulation software.

Optimization of a Residential Air Source Heat Pump using Refrigerants with GWP <150 for Improved Performance and Reduced Emission

Conference Li, Zhenning ; Yana Motta, Samuel ; Shen, Bo ; ...

Using low-GWP refrigerants can reduce the Green House Gas (GHG) emission of heat pump systems. Heat exchangers and compressors are the key components and have a prominent impact on system performance, significant research is devoted to reducing the cost of the heat exchangers while achieving the same or better system performance with refrigerant charge reduction.To better understand the environmental impacts of optimized systems with low-GWP refrigerants, Life Cycle Climate Performance (LCCP) evaluation method was used to evaluate the direct and indirect emissions of the system over the course of its lifetime from manufacturing to disposal.

Optimization of Refrigerant Compositions for Low-GWP Refrigerant Mixtures Using Segment-by-segment Heat Exchanger and Detailed System Models

Conference Li, Zhenning ; Shen, Bo ; Gluesenkamp, Kyle

The recently introduced hydrofluoroolefin (HFO) refrigerants, including R1234yf and R1234ze(E), have significantly lower global warming potentials (GWPs) than traditional hydrofluorocarbon (HFC) refrigerants like R410A. However, prior tests show that direct drop-in of pure R1234yf or R1234ze(E) into equipment designed for R410A results in a decrease in heat exchanger capacity and the system coefficient of performance. The primary reason is the lower in-tube heat transfer performance of R1234yf and R1234ze(E) compared with that of R410A. To address this issue, previous studies have mixed the mildly flammable HFC R32 with HFOs to improve system performance, with HFC R125 also added to suppressmore »« less
