Thermoelectric unit and refrigeration combined efficiency improving system and application method

Abstract

The invention relates to a thermoelectric unit and refrigeration combined efficiency improving system and an application method. Three is no reasonable system and application method utilizing cooperation of refrigeration characteristics and thermoelectric units for efficiency improvement at present. The system comprises a low-pressure cylinder, a generator, a condenser, an evaporator, an absorber,a heat exchanger, a first low-pressure heater, a second low-pressure heater, an air feeder, a circulation pump, a circulation water supply pipeline, a circulation water return pipeline, a coolant water supply pipeline and a coolant water return pipeline. Lower-pressure cylinder air exhaust is connected with an absorption type refrigeration system, the generator is heated through exhaust heat, andsteam generated from the generator through heating enters the condenser; a user can select circulation water for condensing steam or air feeder bypass air for condensing steam according to the outside temperature, when air feeder bypass air is used for condensing, fed air can absorb heat in the condenser, and the efficiency of a boiler is improved. Through the system and method, thermal power plants have the cool supply capacity, existing cool supply modes are changed, and the refrigeration power consumption is reduced.

Description

technical field [0001] The invention relates to the combination of a heat supply unit or a pure condensing unit and an absorption refrigeration system, in particular to an efficiency-improving system and an application method of a thermoelectric unit combined with refrigeration. Background technique [0002] After China entered the 21st century, the economy has developed rapidly, and people's quality of life has been improving. In the hot summer, the demand for refrigeration in large places such as homes and shopping malls is increasing. In addition, major factories also have high requirements for refrigeration due to process design. At present, these refrigeration needs are mainly handled in units of households, factories, and certain buildings. For example, the Chinese patent application number 201110324313.9 uses household air conditioners, central air conditioners, and other equipment to consume electric energy. These methods are large-scale Not big enough, nor economica...
