-- Units profile --
The 20sTB series open vortex water source heat pump units is a central air conditioning system with the world's advanced level of health, environmental protection and energy saving, which is jointly developed by the Starts(Guangzhou)Refrigeration Machinery Manufacturing Co., Ltd. and the National Design Institute of the state a class a. Compared with the conventional air conditioning heating system, the system saves about 50% of the energy saving, which uses the characteristics of the constant water temperature of the groundwater, which can be used as the main energy source and the central air conditioning system of the advanced water source heat pump to meet the needs of heating in winter and the cooling of the summer. The unit has 9 standard specifications, the cooling range is 16kW~150kW, the heating range is 20kw-190kw, the minimum water temperature of the frozen water is 5ºC, the highest water temperature of the hot water is 50ºC.except the standard specifications, it can also be ordered according to the requirements of the user to produce all kinds of non - standard units. In addition, our company can also produce high voltage, seawater source and other power supply products.
-- Advantage --
