Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0022] The working principle of VM circulating heat pump refers to Chinese patent CN101865566A.

[0023] Such as figure 1 As shown, this system can provide domestic hot water, heating in winter and cooling in summer. The main working process is: fuel and air are used by the heat engine (micro gas turbine or internal combustion engine) to drive the generator to generate electricity and supply the user, the flue gas discharged from the heat engine drives the VM circulating heat pump to work, the excess flue gas and the VM circulating heat pump heat chamber heat exchanger The outgoing flue gas is mixed and enters the flue gas heat exchanger, and finally the flue gas is discharged into the atmosphere through the flue gas purification device. When the flue gas discharged from the micro gas turbine drives the VM circulating heat pump to...

Abstract

The invention discloses a distributive energy system of a heat engine driven VM circulating heat pump, and belongs to the field of distributive energy systems. The system comprises such parts as a heat engine, a generator, a VM circulating heat pump, a smoke discharge heat exchanger and a fan coil. The heat engine consumes a fossil fuel to drive the generator to generate electricity; and discharged smoke drives the VM circulating heat pump for heating or cooling. In winter, the fan coil system is connected with a room-temperature cavity of the VM circulating heat pump for heating; and in summer, the fan coil pipe system is connected with a cold cavity of the VM circulating heat pump for cooling. Meanwhile, the system is additionally provided with a hot water supply system. The distributive energy system can supply electric power, cold or heat and living hot water, has such characteristics as energy conservation, environmental protection and flexible operation and adjustment modes, and is specifically suitable for small-volume users.

Description

Technical field [0001] The invention belongs to the field of distributed energy systems, in particular to a distributed energy system coupled with a VM circulating heat pump. Background technique [0002] Distributed energy system has the characteristics of saving power transmission and transformation costs, high reliability of power supply, good environmental protection and realizing the cascade utilization of energy, which is conducive to saving resources and protecting the environment. Existing distributed energy systems mostly use small and medium-sized gas turbines to generate electricity, and then combine waste heat boilers and absorption units as cooling and heating equipment. Generally, they have large capacity and are suitable for residential communities or large public buildings. However, for rural household users or urban villa-type distributed users, due to the relatively small demand for electricity, cold or heat, it is not suitable for small and medium-sized gas tur...
