Problems solved by technology

[0002] The cooling and heating energy-saving system in the prior art cannot adapt to multi-working conditions, and cannot operate in low-temperature and harsh environments. When hot water above 50°C is produced below -20°C, the energy efficiency is low during operation, the compressor load is large, the life is short, the stability and reliability are poor, and the low temperature adaptability and low temperature heating performance cannot be improved, so it needs to be improved urgently.

Abstract

The invention discloses a cascade type refrigerating and heating energy-saving system comprising two air source modules, at least one screw heat source unit, a screw heat source unit water supply pump, an air conditioning system circulating pump, a thermal energy buffer water tank, a heat supply remote transmission main meter and a microbubble exhaust dirt separator. Water ways of the two air source modules are arranged in a series connection manner and are both connected with the thermal energy buffer water tank, and generated thermal energy can be transferred to the thermal energy buffer water tank. The cascade type air source / water source heat pump heating system can operate in multiple working condition modes especially low-temperature severe environments, system operation is stable, and energy efficiency is high. The heating system can efficiently operate under wider temperature environment intervals, and switching of various operation modes can be achieved.

Description

Technical field [0001] The invention relates to the technical field of cooling and heating energy saving, in particular to a cascade cooling and heating energy saving system. Background technique [0002] The cooling and heating energy-saving system of the prior art cannot adapt to multiple operating conditions, and cannot operate in a harsh environment with low temperatures. Its operating temperature environment range is relatively narrow. The operating mode cannot be switched in an ultra-low temperature environment below -20°C. When high temperature hot water above 50℃ is generated below -20℃, the energy efficiency is low during operation, the compressor load is large, the life is short, the stability and reliability are poor, and the low temperature adaptability and low temperature heating performance cannot be improved, so it is urgent to improve. Summary of the invention [0003] Aiming at the deficiencies in the prior art, the present invention designs a cascade cooling and ...
