Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] refer to figure 1 , a solar high-efficiency jet refrigeration system, the system consists of a solar collector 1, a steam generator 2, a secondary ejector 3, a supercharger 4, an evaporator 5, a regenerator 6, a gas condenser 7, and a gas- Liquid injector 8, expansion valve 9 and several valves and pipelines etc. composition.

[0024] The cavity of the steam generator 2 is filled with refrigerant, and the refrigerant is coated with a heat exchanger 201. The heat exchanger 201 and the solar collector 1 form a closed loop, and the refrigerant absorbs the energy of the circulating hot water of the solar collector. After that, a high-temperature and high-pressure refrigerant vapor is formed,

[0025] The two-stage ejector 3 includes a first...

Abstract

The invention discloses a solar high-efficient spraying and cooling system, which comprises a solar heat collector and a vapor generator. A heat exchanger is arranged in the cavity, filled with a coolant, of the vapor generator, the heat exchanger and the solar heat collector form a closed circuit, and after the coolant absorbs energy of circulated hot water of the solar heat collector, high-temperature and high-pressure coolant vapor is formed. The system further comprises a secondary spraying device, an evaporation device and a gas condenser, wherein the secondary spraying device is respectively communicated with the evaporation device and the gas condenser, the high-temperature and high-pressure coolant vapor and low-temperature and low-pressure coolant vapor coming from the evaporation device pass through the secondary spraying device to enter the gas condenser, the low-temperature and low-pressure coolant vapor is formed in the evaporation device, and the temperature of the coolant in the evaporation device is enabled to be lowered to a designed temperature. By utilizing solar energy, the system has the characteristics of reliable working performance, low cost, stable operation and high efficiency.

Description

technical field [0001] The invention relates to vacuum refrigeration equipment, in particular to a solar energy efficient jet refrigeration system. Background technique [0002] Solar jet refrigeration system has good energy saving. The main feature of the steam ejector is the Laval nozzle, which uses steam as the power to make the system obtain a working vacuum, evaporate the refrigerant medium at low temperature, and generate a low-temperature refrigerant. [0003] The use of solar energy to generate a large amount of steam from the refrigerant can effectively reduce energy consumption and reduce the auxiliary facilities of the general steam jet pump system, such as boiler rooms, cold water pump rooms, hot water pump rooms, steam pipes, cooling water pipes, and high vacuum pump rooms. Wait. [0004] However, the general solar jet refrigeration system has low efficiency and complex structure, which is not conducive to large-scale promotion. Contents of the invention ...
