Abstract

The invention relates to an automatic gas-liquid separated condenser for central air-conditioning units, belonging to heat equipment area, comprising upper and lower sealing heads (1), (7) and heat exchanger body (3), characterized in that heat exchanging pipe group (4) is set in the heat exchanger body (3), baffle group (5) is set, air inlet pipe (11) and safety valve (10) are set at the top of upper sealing head (1), steam clapboard (13) is set in the middle, inlet pipe (14) for cooling water is set at the lowest, outlet pipe (12) for cooling water is set at the highest, heat exchanging group (4) is set between pipe board (2) and pipe board (6), a hole connected with the liquid outlet pipe (8) is set at the bottom of lower sealing head (7), upper and lower sealing heads (1), (7) are connected with the heat exchanging body by flange. It can realize automatic gas-liquid separation by gravity so that the steam is contacted with the heat exchanging surface directly, heat exchanging coefficient is maintained higher, and descent of heat exchanging coefficient generated by heat exchanging surface covered with liquid film in conventional condenser is improved.

Description

technical field [0001] The utility model relates to an automatic gas-liquid separation condenser for a central air-conditioning unit, which belongs to the field of thermal equipment. technical background [0002] The condensing heat exchanger is an important part in the refrigeration system, and its quality directly affects the performance of the air conditioning equipment. The heat loss of the condenser accounts for 35.5% of the heat loss of the whole air conditioning equipment. Therefore, inventing a condensing heat exchanger with simple structure, high efficiency and energy saving is of great significance for improving the energy efficiency ratio of the air conditioner, reducing its energy consumption, improving the structure of the condenser, and strengthening its heat transfer. [0003] Traditional condensing heat exchangers use horizontal tubes to condense. As the gas phase continues to condense, the thickness of the liquid film gradually increases, which increases th...
