Technical field
The utility model relates to field of Refrigeration and Air-conditioning, particularly relates to a kind of refrigerant condenser without refrigerant superheat section.
Background technology
China's cooling industry Energy Efficiency Standard improves constantly, and also increases the volume of refrigerated heat exchanger while adopting enhanced heat exchange technology to improve air-conditioning whole efficiency.The exchange capability of heat how improving refrigerated heat exchanger becomes an important research topic.
Fig. 1 is current normal domestic use air conditioner outdoor unit structure figure.Air-conditioner outdoor unit heat exchanger tube is finned tube horizontal transverse-pipe and arranges, connects employing hosepipe type, air relies on blower fan at the outer forced convertion cooling heat transferring of pipe, cold-producing medium is compressed into high temperature and high pressure gas through compressor, and enter condenser and air heat-exchange, cold-producing medium pipe in by superheated vapor, gas-liquid two-phase condensing heat-exchange to subcooled liquid.Along with the carrying out of condensation process, constantly there is condensate liquid to be formed at wall, hinder the heat exchange of steam and wall, constitute the dominant thermal resistance of heat exchange, reduce the coefficient of heat transfer.Along with being on the increase of condensate liquid, the thickness of liquid film of wall constantly increases, and adds that vapor volume reduces the factor of the refrigerant flow rates reduction brought, condensation effect is sharply worsened.Air side, because in-tube condensation liquid thermal resistance causes the temperature of heat exchanger tube outer wall to decline, the driving force of heat exchange reduces, and the heat exchange amount of Forced Air Convection is reduced.In order to reach enough heat exchange amounts, need to increase heat exchange area to meet heat transfer requirements, adopting fin to increase, tube outside is long-pending improves cost of investment, and volume is also larger.
Summary of the invention
The purpose of this utility model is the shortcoming and defect overcoming above-mentioned prior art, provides a kind of refrigerant condenser without refrigerant superheat section.Relative to prior art, adopt condensing heat-exchange to replace superheat section heat exchange, because condensing heat-exchange effect is better, therefore can improve exchange capability of heat.
The utility model is achieved through the following technical solutions:
Without a refrigerant condenser for refrigerant superheat section, it is characterized in that: comprise horizontal lower end liquid pipe 3, be vertically arranged on many groups of vertical heat exchanger tubes 1 on horizontal lower end liquid pipe 3, each group has two vertical heat exchanger tubes 1 to form; Wherein, the upper and lower end of these two vertical heat exchanger tubes 1 in each group is communicated with each via elbow respectively, and forms an independent loop;
One end pipeline of described horizontal lower end liquid pipe 3 is provided with air inlet pipe 4 and drain pipe 6, the pipeline between air inlet pipe 4 and drain pipe 6 is provided with liquid seal device 5, air inlet pipe 4 and drain pipe 6 is separated by liquid seal device 5.
In each group described two vertical heat exchanger tubes 1 lower end elbow by communicating pipe 1-1 and horizontal lower end liquid pipe 3 through.
Axis and the horizontal plane of described vertical heat exchanger tube 1 are perpendicular; The axis of described horizontal lower end liquid pipe 3 parallels with horizontal plane.
The axis of described air inlet pipe 4 and the axis perpendicular of horizontal lower end liquid pipe 3.
Described vertical heat exchanger tube 1 is provided with fin 2.
The control method of above-mentioned refrigerant condenser is as follows:
After cold-producing medium enters air inlet pipe 4 from compressor outlet (with high pressure gaseous), level carries out mass-and heat-transfer after entering and mixing with the saturated liquid in horizontal lower end liquid pipe 3 in horizontal lower end liquid pipe 3 again, mixed saturated gas is assigned in each group of vertical heat exchanger tube 1 by communicating pipe 1-1 and carries out condensing heat-exchange, then, the inwall that refrigerant vapour is condensed into the vertical heat exchanger tube 1 of liquid runs down flows in horizontal lower end liquid pipe 3, after horizontal lower end liquid pipe 3 converges, flow to throttle mechanism through liquid seal device 5; Now form fluid-tight at horizontal lower end liquid pipe 3 and liquid seal device 5, while the refrigerant liquid outflow condenser of condensation, refrigerant vapour can not flow out condenser.
The utility model, relative to prior art, has following advantage and effect:
After cold-producing medium enters air inlet pipe 4 from compressor outlet (with high pressure gaseous), level carries out mass-and heat-transfer after entering and mixing with the saturated liquid in horizontal lower end liquid pipe 3 in horizontal lower end liquid pipe 3 again, and mixed saturated gas is assigned in each group of vertical heat exchanger tube 1 by communicating pipe 1-1 and carries out condensing heat-exchange; Now no longer there is superheated vapor in the vertical heat exchanger tube 1 of each group, relative to prior art, condensing heat-exchange ability improves greatly.
One end pipeline of the utility model horizontal lower end liquid pipe 3 is provided with air inlet pipe 4 and drain pipe 6, the pipeline between air inlet pipe 4 and drain pipe 6 is provided with liquid seal device 5, air inlet pipe 4 and drain pipe 6 is separated by liquid seal device 5.Axis and the horizontal plane of described vertical heat exchanger tube 1 are perpendicular; The axis of described horizontal lower end liquid pipe 3 parallels with horizontal plane.The change of this structure, due in the Action of Gravity Field lower end liquid pipe 3 that made condensate stream arrive, decreases the refrigerant liquid scale of construction of accumulating in vertical heat exchanger tube 3, namely decreases the liquid phase burden of condenser, the filling quantity of refrigerant of air-conditioner set is reduced.
Because the condensation of refrigerant thickness of liquid film in heat exchanger tube is thinning, such that the condensing heat-exchange thermal resistance of refrigerant side reduces, cooling energy recovery increases, condenser overall heat-transfer coefficient increases, and heat exchange efficiency improves.
The technological means that the utility model adopts, can improve the heat exchange property of refrigerant condenser, difficulty of processing is low, with low cost.
