Honeywell: refrigerant and high temperature heat pump refrigerant research and development

On December 7, 2007, the International Forum on ODS Phase-Out and Alternative Technology Development for HCFCs, sponsored by the China Refrigeration and Air-Conditioning Industry Association, was grandly held at the Nikko Hotel New Century Beijing. From the State Environmental Protection Administration, China Refrigeration and Air Conditioning Industry Association, the Chinese Institute of Refrigeration and Trane, Carrier, McQuay, Johnson Controls, Dalian Bingshan, Yantai Binglun, Qingdao Haier HVAC and other business representatives attended more than 200 enterprises Second forum. Mr. Zhang Ke from Honeywell Special Materials Department made a keynote speech on this forum entitled "Development and Application of Efficient Refrigerant and High Temperature Heat Pump Working Medium". Zhang Section in his speech is divided into three parts: First, R410A home air conditioning features and costs Prospects: R410A system will have a period of rapid growth (a) the introduction of environmental laws and regulations: Montreal September 16, 2007 meeting on China The elimination of HCFC gives a specific timetable. (B) of the energy efficiency regulations: the new air-conditioning energy standards, the existing standards will be upgraded two grades, making R410A system and the R22 system costs are very close. (C) the system is compact, lower voice, prompting users of R410A air-conditioning of all ages. (D) Many companies have been developing R410A small chiller units, expanding the R410A applications. Second, the very low GWP refrigerant for automotive air conditioning Fluid H through the physical characteristics of the automotive air conditioning refrigerant Fluid H, compatibility testing and sample test results on the car, the conclusions: 1, a non-flammable, very low GWP refrigerant is determined, the performance evaluation results are very exciting 2, air conditioning system and real car test: (1) The initial test results show that Fluid H system and the R134a system is very close. (2) A slight decrease in cooling capacity can be solved by: a Changing or adjusting the expansion valve b Changing the temperature / pressure control point or adjusting the compressor suction valve parameters. (3) Heat exchanger improvements or optimizations (especially evaporator refrigerant flow paths) 3. Initial material compatibility testing found no problems and further testing is still required. 4. This refrigerant is a potential cost and Superior performance alternative R134a Third, Honeywell high temperature working fluid HAS09 Background information: Headquartered in Morristown, NJ, Honeywell Specialty Materials Group is a global leader in providing customers high performance specialty materials with annual sales of 4.7 billion U.S. dollars.
