YXY type vacuum pressurized injection and vacuum evaporation refrigerating device

Abstract

The invention relates to a YXY type vacuum pressurized injection and vacuum evaporation refrigerating device. The device consists of an evaporating tank, a storage tank, a rotary vane vacuum / pressurized injection pump or a self-suction injection pump, a vacuum meter, a pressure gauge, an injector, a check valve and a liquid discharging valve which are connected in series sequentially. The device is characterized in that: the liquid level in the evaporating tank and the liquid level in the storage tank are at the same horizontal position; and the rotary vane vacuum / pressurized injection pump simultaneously sucks a vaporous refrigerant and a liquid refrigerant from the input end of the rotary vane vacuum / pressurized injection pump. The device has the advantage of opening a new world for more widely using a Carnot cycle theory. Technical measures of vacuum and pressurized injection and evaporation refrigeration are taken by using the high-vacuum self-suction vaporous / liquid mixed injection pump. Only 1.6 to 2 atmospheric pressure of refrigerants is only required, and the liquid flow rate is only 0.2kg / second although the gas flow is up to 4 liters / second, so that a motor with the power of 1,200 watts is required only. An embodiment of the invention is given by combining attached figures.

Description

technical field [0001] The invention relates to a YXY type vacuum pressurized injection and vacuum evaporation refrigeration device. Background technique [0002] As we all know, the technology of using compressor refrigeration is an extremely mature technology, especially the Carnot cycle theory, which has always been regarded as an unshakable classic theory. But it is a pity that the existing technology only uses the vapor compression refrigeration method in the Carnot cycle theory to complete, and gives up the technical application of the more excellent vacuum evaporation and heat absorption refrigeration process. Strictly speaking, the methods of existing refrigeration technology are incomplete, and they are a forgotten corner of refrigeration science research. Contents of the invention [0003] The object of the present invention is to provide a YXY type vacuum pressurized injection and vacuum evaporative refrigeration device. [0004] One of the technical schemes a...
