Embodiment Construction

[0054] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0055] see figure 1 , figure 2 As shown in the embodiment, the water evaporation energy engine is connected to the outer dehumidifier 20 by the finished air outlet 15 of the spiral dew point indirect evaporative cooler, and connected to the air inlet 1 of the coil dew point indirect evaporative cooler, forming a freezing point indirect Evaporative cooler, solar energy, low-level energy collector of atmospheric thermal energy, piston engine, and thermoelectric engine are composed. The working cycle process: the dehumidifier 20 dehumidifies the primary air with sub-dew point temperature generated by the spiral dew point indirect evaporative cooler, Reduce the specific humidity to d≥3.5g steam / kg dry air, and then perform internal dehumidification, adiabatic humidification and heat exchange cycles in the coil cooler to produce finished air wit...

Abstract

The invention discloses a freezing point indirect evaporation cooling type natural low-phase energy engine taking water as a raw material and aims to provide an indirect evaporation cooler which can dehumidify and reduce the temperature to the temperature close to a freezing point; the indirect evaporation cooler is used as a cold source of an air conditioner or an engine and also can collect solar energy; and atmosphere heat energy is used as a hot source to drive a piston type engine and a thermoelectric engine to work so as to output mechanical energy and electric energy. The technical points are as follows: the freezing point indirect evaporation cooler takes finished air and cold medium water which are close to the freezing point and are generated by carrying out heat-insulating dehumidification and heat exchange on primary air until d is more than or equal to 3.5 grams steam in each kilogram of dry air as a cold source, and takes an atmosphere heat energy solar low-phase energy heat exchanger as a hot source; a circulating work medium refrigerating agent is subjected to heat exchange and expansion with a heat source in a heat collector coiled pipe (14) to drive a piston engine to output mechanical energy; and the refrigerating agent is subjected to heat exchange with the cold source in a thermoelectric engine coiled pipe (54) to be converted into electric energy; and meanwhile, the refrigerating agent is subjected to temperature reduction and is retracted and circulated.

Description

Technical field: [0001] The invention relates to a heat engine, in particular to an engine utilizing a cold source and a natural low-level heat source that are cooled by evaporation of water to reach a subfreezing point. Background technique: [0002] At present, the indirect evaporative cooler used: mainly uses the adiabatic humidification process of water to achieve cooling (see: "Evaporative Cooling Technology" by Meng Hua and Long Weiding, "Energy Technology", Volume 24, August 2003 No. 4, pages 170-177.) and developed to a series combination of multiple cooling units to achieve a cooler close to the local dew point temperature (see: Zhang Qiang's "Research Progress and Status Analysis of Dew Point Indirect Evaporative Cooling Technology", " Refrigeration and Air Conditioning "Volume 10, No. 1, February 2010, pages 17-22.), based on the analysis of the air supply state, the heat-humidity ratio affects the cooling effect of the indoor air supply, and only when the tempera...
