United Technologies' Vice President of Environment, Controls & Security for Greater China and Aftermarket Services, Gao Zhichang said, "Since the introduction of the world's first centrifugal chillers in 1922, Carrier has maintained its leadership in the field. The launch of the 19XR-E is a testament to Carrier's commitment to innovation and its strength in the HVAC market." At the 2013 China Refrigeration Exhibition, Carrier also unveiled a series of new commercial and light commercial solutions, including the 30XW-V variable speed screw chillers with cooling capacities ranging from 170 tons to 460 tons. These chillers integrate innovative Greenspeed? technology, demonstrating excellent performance and energy efficiency in stringent industrial and commercial applications. The modular air-cooled screw chillers use the environmentally friendly refrigerant HFC410A, offer flexible combinations, are easy to install and compact, and meet the cooling and heating needs of buildings of different sizes.

(4) Water-source heat pumps offer significant environmental benefits. The operation of water-source heat pump units is pollution-free, allowing them to be installed in residential areas without combustion, smoke emissions, or waste. They do not require storage space for fuel waste and do not necessitate long-distance heat transfer.

Taking Jiangsu Shuangliang, a market leader, as an example, it is about 1.1 to 1.2, such as the direct-fired double-effect H-type lithium bromide water chiller. In lithium bromide absorption refrigeration, due to the high boiling point (1265℃) of the lithium bromide aqueous solution itself, it is extremely difficult to vaporize, so the steam above the saturated solution of lithium bromide can be considered pure water vapor; at a certain temperature, the saturated partial pressure of water vapor above the lithium bromide aqueous solution is less than that of pure water; and the higher the concentration, the lower the saturated partial pressure of water vapor above the liquid surface. Therefore, under the same temperature conditions, the higher the concentration of the lithium bromide aqueous solution, the stronger its ability to absorb water. This is also why lithium bromide is commonly used as an absorbent and water as a refrigerant. The lithium bromide absorption refrigeration unit is mainly composed of several parts: generator, condenser, evaporator, absorber, heat exchanger, and circulating pump. During the operation of the lithium bromide absorption refrigeration unit, when the lithium bromide aqueous solution in the generator is heated by the heat medium water, the water in the solution continuously vaporizes; with the continuous vaporization of water, the concentration of the lithium bromide aqueous solution in the generator increases continuously and enters the absorber; the water vapor enters the condenser, is cooled by the cooling water in the condenser, and condenses into high-pressure, low-temperature liquid water; when the water in the condenser passes through the throttle valve into the evaporator, it rapidly expands and vaporizes, absorbing a large amount of heat from the refrigerant water in the evaporator during the vaporization process, thereby achieving the purpose of cooling and refrigeration; in this process, the low-temperature water vapor enters the absorber and is absorbed by the lithium bromide aqueous solution in the absorber, the concentration of the solution gradually decreases, and is then sent back to the generator by the circulating pump to complete the entire cycle. This cycle continues endlessly, continuously producing cold. Since the dilute lithium bromide solution in the absorber has been cooled and has a low temperature, in order to save the heat required to heat the dilute solution and improve the overall thermal efficiency of the unit, a heat exchanger is added to the system, allowing the high-temperature concentrated solution flowing out of the generator to exchange heat with the low-temperature dilute solution flowing out of the absorber, thereby increasing the temperature of the dilute solution entering the generator.
