large temperature difference air conditioning system features
1, reduce the water flow, you can reduce the diameter of the water system piping
2, you can choose a smaller number of pumps
3, reduce the initial investment in the water system
4, so that the space occupied by the pipe shaft smaller
5, better save water resources
6, so that the operating costs of the system is greatly reduced
Product Examples
McWhirr two-stage compression centrifugal chiller WTCC, cooling capacity: 2110~5627kW, refrigerant: R134a
Picture
■Double-stage compression: It can provide a larger pressure ratio to fully compress the refrigerant, obtaining higher operating efficiency and expanding the range of compressor working conditions, reducing the risk of compressor wheezing under low load, so that the unit can still operate safely and stably at reduced load and low load.
High efficiency and energy saving: the COP of the national standard working condition at full load can reach 7.0, and the IPLV can reach 11.4, which meets the national level energy efficiency and the three-star standard of green building, and becomes the energy efficiency star of the chiller unit with its superior performance, and cuts down the operation cost of the system later significantly.
Flash economizer: the economizer is equipped with a two-stage throttling float valve, the high-pressure liquid refrigerant from the condenser enters the economizer partly through throttling to make the other part of the refrigerant subcooling, and the refrigerant gas produced by throttling enters the compressor for the second-stage compression, which improves the capacity and efficiency of the refrigerant system as a whole.
■Electrical Expansion Valve: Adopting high-precision electric expansion valve level control method, the condenser level is detected in priority, and a signal is sent to control the opening of the expansion valve according to the level, which can be accurately adjusted within the range of the full energy regulation of the unit, and enhance the efficiency and reliability of the unit.
Built-in oil pump design: The built-in oil pump design of the compressor makes the piping of the unit simpler, and there is no risk of lubricant leakage. At the same time, it adopts the unique oil ejection technology to eject the lubricating oil accumulated at the bottom of the heat exchanger and compressor back to the oil tank in time, so as to avoid the reduction of heat exchange efficiency due to the entry of lubricating oil into the refrigerant system.
Wide range of applications: the unit can not only meet the operation of conventional chilled water conditions, but also can be used in large temperature difference, water storage cooling and other energy-saving air conditioning systems, large lifting force compressor to ensure that the unit in the harsh conditions of energy efficiency performance is still excellent.
