Low-pressure steam, high-pressure steam and high-temperature hot water triple-supply water actuating medium heat pump system

Abstract

The invention provides a low-pressure steam, high-pressure steam and high-temperature hot water triple-supply water actuating medium heat pump system. The system comprises a low-grade waste heat recovery heat pump subsystem and a steam hot water triple supply subsystem, wherein the low-grade waste heat recovery heat pump subsystem and the steam hot water triple supply subsystem both adopt a wateractuating medium, and the low-grade waste heat recovery heat pump subsystem is connected with the steam hot water triple supply subsystem through a condenser. According to the system, the natural water actuating medium is used as a working medium of the whole heat pump system, the water actuating medium has no damage effect on atmospheric ozone, the greenhouse effect is not generated basically, the use of an artificial synthetic actuating medium with high damage to an ozone layer and high greenhouse effect is avoided, and the environment is effectively protected.

Description

technical field [0001] The invention relates to the field of heat pump systems, in particular to a hydraulic medium heat pump system for triple supply of low-pressure steam, high-pressure steam and high-temperature hot water. Background technique [0002] Energy is the material basis for the survival and development of human society. The shortage of energy will make society lose its motivation for development. Environmental protection is the core link for the healthy and sustainable development of society. The lack of the concept of green environmental protection will destroy the long-term stability of social development. At present, with the rapid development of the world economy, the consumption of energy has increased sharply. At the same time, the environmental pollution generated in the process of development has always troubled the whole world. Energy and environmental issues have become the focus of attention all over the world. It has become the consensus of the whol...

Problems solved by technology

[0004] However, as a system that requires a large amount of circulating working fluid, heat pumps also face the problem of selecting circulating working fluids. In areas where artificial synthetic working fluids such as chlorofluorocarbons seriously damage the ozone layer, have a significant impact on the greenhouse effect, and have limited use and development prospects In the background, the choice of heat pump cycle working medium needs to be more cautious, which also seriously restricts the application of heat pumps in all aspects of production and life

At the same time, the temperature of thermal energy required in industrial production and daily life is getting higher and higher, and thermal energy is basically utilized in three forms: low-pressure steam, high-pressure steam, and high-temperature hot water. However, the heating temperature of many heat pumps is low. The process can only provide one of the heat output methods, which seriously restricts the value of the heat pump in the actual use process
