Embodiment Construction

[0013] In the following, a combined power cycle and compression refrigeration cycle device of the present invention will be further described in detail with reference to the accompanying drawings.

[0014] The system composed of a combination of power cycle and compression refrigeration cycle of the present invention includes two cycle modes: power cycle II and refrigeration cycle I, the specific cycle method:

[0015] First, the working fluid from the outlet of the accumulator 4b is preheated by the regenerator 2, and then passes through the working fluid pump 7 and the evaporator 28 to absorb heat and increase the pressure, and then expands in the expander 9 to output shaft work, and then comes out of the expander. The gaseous working fluid in the regenerator 2 exchanges heat with the liquid working fluid from the outlet of the accumulator 4b and then enters the condenser 3 to further condense and release heat, and then return to the accumulator 3 for the next power cycle II.

Abstract

The invention discloses a device for combining power cycle with compression type refrigerating cycle, which can be used for simultaneously completing power cycle and compression type refrigerating cycle. The device comprises a compressor, a heat regenerator, a condenser, a reservoir, a throttle valve, an evaporator I, a working medium pump, an evaporator II, an expander and a transmission device, which are connected according to a rule. According to the device disclosed by the invention, medium-low-grade energy sources such as solar energy, geothermal energy and industrial waste heat can be utilized for driving the expander to apply work, so that the compressor is driven by the output shaft work to operate for achieving the power cycle and the refrigerating cycle. Meanwhile, the device can also be used for generating power when the operation of a refrigerating working condition is not needed. The heat regenerator is additionally arranged in the device, so that the load of the heater is reduced while the load of the condenser is reduced. The reservoir is arranged, so that the two cycles are operated independently, thereby ensuring stable refrigerating to a user. The device disclosed by the invention has a good application prospect in underserved areas of power or small areas or cold supply, and is of significance to energy conservation and emission reduction.

Description

Technical field [0001] The invention relates to a combined device of a power cycle and a compression refrigeration cycle using medium and low-grade energy such as solar energy, geothermal energy, industrial waste heat and the like. Background technique [0002] The air-conditioning industry is a big energy consumer, generally accounting for 40%-60% of total building energy consumption. At present, most of the compression refrigeration methods are driven by electric energy, which consumes a large amount of high-grade electric energy, which brings great pressure on energy and the environment. In the current environment with increasingly tight energy and serious environmental pollution, achieving energy conservation and emission reduction is a problem that the refrigeration industry has to face. Therefore, reducing the use of high-grade energy and seeking to use low- and medium-grade energy to achieve refrigeration has received widespread attention. Low- and medium-grade energy so...
