Low-power-consumption jet type refrigerating system equipped with thermal driving pump

Abstract

The invention belongs to the technical field of refrigeration, and provides a low-power-consumption jet type refrigerating system equipped with a thermal driving pump. The system comprises a jet type refrigeration cycle and a heat collection cycle. The jet type refrigeration cycle comprises a high-pressure container, a generator, an ejector, an evaporator, a condenser, a liquid storage device, a mixing chamber, the thermal driving pump, an electronic expansion valve, a mass flow meter, an adjustable valve and the like, wherein the high-pressure container is mainly used for generating the high-pressure gas. The heat collection cycle mainly adopts low-grade heat energy to serve as a heat source to heat a heat-carrying agent, then the heat-carrying agent is driven by a water pump to exchange heat with working media in the high-pressure container and the generator, and energy transfer is achieved. Compared with the prior art, the system has the advantages that the low-pressure liquid-phase working media can be effectively driven by the high-pressure gas-phase working media; and the thermal driving pump is adopted in the jet type refrigerating system to replace a mechanical pump, so that high-efficiency operation of all parts in the system is ensured, and no pump and the low power consumption of the jet type refrigerating system are really realized.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a low-power-consumption jet refrigeration system equipped with a heat-driven pump. Background technique [0002] As the most widely used general-purpose machinery after motors, mechanical pumps play an important role in many fields such as daily life, agricultural production, mining, electric power, ships, and textiles. According to statistics, the electricity consumption of mechanical pumps in my country accounts for about 20.9% of the national electricity consumption. With the depletion of fossil fuels and the aggravation of environmental pollution, people are increasingly worried about the application and development of future energy. Therefore, alternative products are sought. To reduce the application of mechanical pumps has gradually become the focus of many scholars' research. [0003] In this context, the corresponding research on thermally driven pumps ...
