Computing method for determining thermal performance of hot water single-effect-type lithium bromide refrigerator

Abstract

The invention discloses a computing method for thermal performance of a hot water single-effect-type lithium bromide refrigerator. On the basis that the heat source parameters of the hot water single-effect-type lithium bromide refrigerator are different, standard design of the lithium bromide refrigerator cannot be achieved easily, and if independent design is made according to heat sources and users, a large amount of manpower and time generally need to be consumed for tedious thermodynamic cycle calculation. The computing method for the thermal performance of the hot water single-effect-type lithium bromide refrigerator includes the steps of collecting and measuring the relevant parameters, selecting the design parameters of the refrigerator, calculating the thermodynamic cycle point parameters, calculating equipment loads and determining refrigerating capacity. By adoption of the computing method, the refrigerating capacity and the working hot water outlet temperature of the hot water single-effect-type lithium bromide refrigerator can be calculated accurately, a basis can be provided for the allocation plan of the hot water single-effect-type lithium bromide refrigerator in engineering, and therefore the heat efficiency of the whole engineering system can be made maximal, and the purpose of energy saving and consumption reduction is achieved ultimately.

Description

technical field [0001] The invention relates to refrigeration equipment in the field of thermal energy engineering, in particular to a method for calculating the thermal characteristics of a hot water single-effect lithium bromide refrigerator. Background technique [0002] Natural gas distributed energy is a comprehensive energy utilization system distributed at the user end. It is mainly based on gaseous fuel and supplemented by renewable energy. It generates electricity through gas turbines or internal combustion engines, and passes the tail flue gas through energy conversion equipment to produce the heat energy utilization forms required by users, such as steam, domestic hot water, heating hot water or Heat energy for refrigeration, etc.; according to the principle of "temperature matching, cascade utilization", the comprehensive energy utilization rate of the natural gas distributed energy system is greater than 70%. The development of natural gas distributed energy is...
