Engine-driven water source compression type heat pump water vapor modulating machine

Abstract

The invention discloses an engine-driven water source compression type heat pump water vapor modulating machine. By utilizing the engine-driven water source compression type heat pump water vapor modulating machine, investment of a power generator and an electric motor can be saved, power generation loss, power transmission loss and electric loss are avoided, and a pay back period is shortened by 50%; flash evaporation heat is provided by circulating supplementing water which is heated by heat pump heating, sleeve cylinder reheating and smoke reheating in a step manner; secondary steam is generated by throttling, spraying and flash-evaporating; the secondary steam is thermally compressed by pipe network residual pressure, so that (n+1) parts of medium-pressure water vapor is modulated by 1 part of high-pressure water vapor; water vapor modulating circulation and hot water heating circulating are realized by switching; and 3 parts of boiler heat is generated at most by one part of a fuel thermal value.

Description

(1) Technical field [0001] The invention relates to an engine-driven water source compression heat pump water vapor conditioner. (2) Background technology [0002] Distributed energy systems provide energy for areas that are not suitable for building centralized power stations, as well as for end users of transmission and distribution networks, effectively reducing transmission losses and investment in transmission systems for electricity, heat, and cold, and providing users with high-quality, highly reliable clean energy services . [0003] In addition, considering the transmission loss and the highest steam pressure requirement, the steam pipe network usually maintains a pressure above 10bar. However, the actual steam pressure demand of many heat-consuming equipment is only 3-4 bar, so a temperature reduction and pressure reducing valve will be installed at the equipment port to meet the equipment pressure demand, thus generally wasting the residual pressure of the steam ...

Problems solved by technology

[0007] (2) When the absolute pressure difference exceeds 3-8bar, the isentropic efficiency of the water vapor compressor is greatly reduced, resulting in an increase in power consumption;

[0008] (3) If the absolute pressure difference of the water vapor compressor is reduced, the cycle pressure ratio of the water source heat pump needs to be increased, resulting in an increase in the power consumption of the water source heat pump;

[0009] (4) Due to the increase in system investment and power consumption, the project investment payback period exceeds 7 years, so it is difficult to popularize and apply
