Patent Searching and Data


Title:
多シリンダ2段式EVI圧縮機および空気調和装置、ヒートポンプ給湯機ならびに制御方法
Document Type and Number:
Japanese Patent JP6987754
Kind Code:
B2
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.
