Title:
MULTI-TANK DUAL-STAGE ENTHALPY INCREASING COMPRESSOR AND AIR CONDITIONER, HEAT PUMP WATER HEATER AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/088586
Kind Code:
A1
Abstract:
A multi-tank dual-stage enthalpy increasing compressor comprises a lower cover plate (10), a lower flange (9), an upper division plate (4), a middle division plate (5), and at least one middle cavity volume formed between each pair of the lower cover plate (10) and the lower flange (9), and the upper division plate (4) and the middle division plate (5). A total middle cavity volume is a sum of all middle cavity volumes. A ratio of a product of a volume ratio and the total middle cavity volume or one volume of the total middle cavity volume to the square of a secondary tank output volume is within a specified range. An air withdrawal volume ratio is a ratio of a secondary stage air withdrawal volume to a primary stage air withdrawal volume. The compressor provides stable air withdrawal at a secondary tank and smooth air release at a primary tank in a dual-tank or triple tank arrangement by configuring reasonable middle cavity volumes, effectively improving a problem in which a pressure fluctuation of an internal cold forming agent in a dual-stage compressor tank is too large, thus achieving smooth operation performance, and reducing a noise of the compressor. Also provided are an air conditioner or heat pump water heater of the compressor, and a compressor control method controlling the compressor.
