Abstract

A method and system for circulating combined cooling, heating and power with a jet cooling device. An outlet of a working medium pump which is used to pressurize liquid working medium is connected to an inlet of a heater. An outlet of the heater is connected to an inlet of an expansion component. An outlet of the expansion component is connected to an inlet of a cooler. An outlet of the cooler is connected to a primary inlet of a jetting device. Primary outlets of the jetting device are respectively connected to an inlet of the working medium pump and an inlet of a throttle valve. An outlet of the throttle valve is connected to an inlet of an evaporator. An outlet of the evaporator and a gaseous outlet of the jetting device are both connected to an inlet of a pressurization component.

Dependent claims

A method for circulating combined cooling, heating and power with a jet cooling device, comprising the following steps:

step 100:
allowing a liquid circulating working medium pressurized by a working medium pump to enter a heater for heat absorption to obtain a high-temperature and high-pressure circulating working medium;
step 200:
allowing the high-temperature and high-pressure circulating working medium to enter an expansion component to expand and produce work and to output shaft work to an outside to generate a low-pressure and high-temperature circulating working medium;
step 300:
allowing the low-pressure and high-temperature circulating working medium mixed with a working medium from a pressurization component to enter a cooler to be cooled by a cooling medium to obtain a low-temperature and low-pressure circulating working medium in a near-critical state;
step 400:
allowing the low-temperature and low-pressure circulating working medium to enter a jetting device to achieve self-cooling through jetting vaporization to obtain a first gaseous working medium and a low-temperature liquid working medium, a first part of the low-temperature liquid working medium directly enters the working medium pump, and a remaining part of the low-temperature liquid working medium enters an evaporator after being throttled and decompressed by a throttle valve;
and
step 500:
allowing the low-temperature liquid working medium to exchange heat with a heat-dissipation medium in the evaporator to generate a low-temperature medium so as to supply a cold source to a user;
allowing a first mixture of the first gaseous working medium from the jetting device and a second gaseous working medium formed by the heat absorption in the evaporator to enter the pressurization component to be pressurized;
after the first mixture is mixed with the low-pressure and high-temperature circulating working medium from the expansion component to form a second mixture, allowing the second mixture to enter the cooler again to complete an entire circulation process.
