Vapor-suspending condensation heat source column and heat pump heating station

Abstract

A vapor-suspending condensation heat source column and heat pump heating station is characterized by comprising a suspending condensate nano-liquid absorbent heat source system and a very-low-temperature heat pump and off-peak power superposed heating system. The station herein has the high-conductive heat transfer characteristic of a nano fluid arranged therein and that of a nano-coated salt-spray-corrosion-resistant alloy fins arranged outside; the renewable energy, greenhouse haze wet-cold heat source, can be absorbed to efficient utilization for wet-cold heat source suspended phase changeand frost-free heat collection and absorption. The station herein provides compensation through a multi-split fixed-frequency compressor module; compensation on the attenuation of a very-low-temperature ambient compressor at -15 DEG C and below is satisfied, heating is achieved in cold weather by combined heat and power generation, electricity output is increased, and an off-peak power superposedheating device is started to compensate the insufficient heating of a heat pump in the cold weather. The station herein also delivers low-temperature cold flows to the atmosphere so as to guide peaksand expel haze, so that the economy and social benefit of manual haze treatment by cold sources are achieved.

Description

technical field [0001] The "water vapor suspension condensing heat source tower heat pump heating station" involved in the present invention involves the two major fields of my country's new energy-saving technology, environmental protection and resources. Background technique [0002] The cold and humid heat source in winter is the water vapor cycle formed by the evaporation of water produced by solar energy heating the earth's surface, and forms a mixed source of water vapor and greenhouse smog with the waste gas + waste heat emitted by humans using fossil energy, which is the greenhouse effect renewable energy. The radiant heat reaches the earth and prevents the long-wave radiation heat from the earth's surface from spreading heat energy to outer space, so that the surface temperature is in a state of balance. Since the industrial revolution, fossil energy has been used as the main consumption, including combined heat and power generation heating waste gas + waste heat, v...

Problems solved by technology

[0005] Improvement problems existing in heat pump units: All manufacturers are still stuck in the large temperature difference structure design based on the heat source of water source heat pumps at 10-15°C, and adopt a single-head compressor structure, which cannot meet the needs of module compensation for compressor attenuation in ultra-low temperature environments below -15°C Demand leads to a reduction in heating capacity. At a low heat source temperature of -15°C, the evaporator has poor performance in absorbing low-temperature heat sources. The gas entering the compressor is unsaturated wet steam, resulting in severe frosting of the compressor and low COP value. become the first bottleneck

[0006] The heat source absorption heat transfer device needs to be improved: the built-in heat transfer carrier used in the closed heat source tower to absorb heat and the low temperature heat source is the traditional water antifreeze solution. The performance index is limited to -10°C air temperature operation, breaking through below -15°C to absorb ultra-low temperature air heat source becomes the second bottleneck
