Abstract

The invention discloses a water-source ultrahigh temperature heat pump which comprises a compressor, an oil separator, a pressure maintenance valve, a condenser, an evaporator, an oil cooler, first and second drying filters, a throttling device, a sub-cooler, first, second, third and fourth stop valves, an oil flow switch, first, second, third and fourth solenoid valves and a liquid spraying valve. A large quantity of parts used on a present common heat pump unit can be used by thewater-source ultrahigh temperature heat pump; the research and development cost is lowered; the production cost is effectively lowered; the energy efficiency ratio of the heat pump is increased; the oil return problem is solved; the water-source ultrahigh temperature heat pumpcan long-term reliably and stably run under high-temperature severe working conditions.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a water source ultra-high temperature heat pump. Background technique [0002] Aiming at a large amount of high-temperature industrial wastewater generated in petrochemical, food and tobacco, power industry, printing and dyeing industries, and these users have high-temperature hot water needs above 90°C in production processes and life, ultra-high temperature heat pump technology can be used to achieve efficient use of energy within industrial processes. At present, the heating outlet temperature of ordinary heat pump devices can only reach 60°C, and some high-temperature heat pump devices can only reach about 80°C outlet water. For heat pumps above 90°C, the main problems are high exhaust temperature, low system efficiency, and poor oil return. , Whether the unit can operate stably, reliably and efficiently for a long time. Contents of the invention [0003] The purpos...
