Outdoor unit condenser, outdoor unit and inverter air conditioner

Abstract

The invention relates to the technical field of air conditioning, in particular to an outdoor unit condenser, an outdoor unit and an inverter air conditioner. The invention aims at solving the problemthat an existing air conditioner is low in heating efficiency. To achieve the purpose, the outdoor unit condenser comprises a heat exchange pipe section, a supercooling pipe section, a throttling element, supercooling connecting pipes and a plurality of supercooling valves, wherein the first end of the supercooling pipe section can be connected with an indoor unit evaporator through a main capillary pipe; the position between the first end and the second end of the supercooling pipe section is divided into n supercooling intervals through the supercooling valves; the plurality of supercoolingintervals are connected with the first end of the throttling element through the supercooling connecting pipes respectively; the second end of the throttling element is connected with the heat exchange pipe section; and the effective length of the supercooling pipe section can be adjusted by controlling opening and closing of each supercooling valve. By means of the arrangement mode, the heatingenergy efficiency can be improved, and frosting is restrained.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an outdoor unit condenser, an outdoor unit and an inverter air conditioner. Background technique [0002] Traditional inverter air conditioners only assess cooling energy efficiency and power, and use cooling energy efficiency as the energy efficiency grade evaluation standard, but have no requirements for heating power and capacity. Therefore, when developing inverter air conditioners, R&D personnel generally use the best cooling energy efficiency as the design principle. However, with the promulgation and implementation of the new national energy efficiency standards, the cooling, heating power and energy efficiency of the inverter air conditioner are included in the assessment scope, and the heating energy efficiency has a great impact on the overall energy efficiency of the air conditioner, so reduce the heating power of the inverter air conditioner, improve Its heat...
