Water source type high-temperature heat pump with adjustable outlet water temperature and temperature adjusting method thereof

Abstract

The invention relates to the technical field of heating and ventilation. The invention discloses a water source type high-temperature heat pump with the adjustable outlet water temperature. The pump includes an oil-gas separator, the upper end of the oil-gas separator is connected with a high-temperature and high-pressure scroll compressor through a low-pressure side sensor; the other end of the working medium filter is connected with a low-pressure side needle valve, the other end of the low-pressure needle valve is connected with an evaporator (a heat absorption end), the output end of the evaporator is connected with a heat source side water outlet, and the lower end of the heat source side water outlet is provided with a heat source side water inlet. The left end of the compressor is connected with a high-pressure side sensor, the end, away from the compressor, of the high-pressure side sensor is connected with a high-pressure side needle valve, the left end of the high-pressure side needle valve is connected with a condenser (a heat output end), and the output end of the condenser is connected with a hot water side water outlet. According to the invention, the heating temperature is increased, the exhaust temperature as high as 120 DEG C and the high-temperature water above 100 DEG C are widely applied to enterprise production, and 100% of natural gas hot water boiler and30% of steam boiler can be replaced.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation, in particular to a water-source high-temperature heat pump with adjustable outlet water temperature and a temperature adjustment method thereof. Background technique [0002] At present, most of the heat pumps on the market are medium and low temperature heat pumps. Due to the limitations of compressors and common working fluids, the temperature of the outlet air (outlet water) does not exceed 55°C. The scope of application is only limited to bathing and initial heating. It can't do anything about higher-end heat demand (such as drying, concentration, dissolution, etc. in the production heat of enterprises). On the other hand, the temperature demand for heat in the production of enterprises is mostly concentrated in the range of 75----115°C, some processes must reach a temperature above 135°C, and the discharge of waste heat is mostly concentrated in the range of 35-60°C (Both a...

On the other hand, the temperature demand for heat in the production of enterprises is mostly concentrated in the range of 75-115°C, some processes must reach a temperature above 135°C, and the discharge of waste heat is mostly concentrated in the range of 35-60°C (Both are discharged in the form of water or gas), so the functionality of medium and low temperature in the thermal energy recycling of enterprises is relatively lacking
