Abstract
An air conditioner outdoor unit equipped with rapid defrosting and anti-freezing functions comprises an outdoor heat exchanger; a defrosting heat exchanger is arranged below the outdoor heat exchanger; an auxiliary capillary and one end of a solenoid valve which are connected in parallel are communicated with a distributor of the outdoor heat exchanger; and the other end of the solenoid valve is communicated with one end of the defrosting heat exchanger. An anti-freezing heat exchanger is arranged below the defrosting heat exchanger; and one end of the anti-freezing heat exchanger is communicated with the other end of the defrosting heat exchanger. The anti-freezing heat exchanger is arranged in a drain pan. One end of a component which is formed by the solenoid valve and the auxiliary capillary in parallel is communicated with the outdoor heat exchanger, and the other end thereof is communicated with the defrosting heat exchanger and the anti-freezing heat exchanger; by controlling the working status of the solenoid valve and the auxiliary capillary, different efficacies under the cooling or heating mode are realized; the invention has the advantages of simple and reasonable structure, good defrosting effect, and can effectively prevent the interior of the drain pan from freezing.
Description
Technical field
The present invention relates to a kind of air-conditioner outdoor unit, particularly a kind of air-conditioner outdoor unit with rapid frost melting and antifreeze function.
Background technology
Common air-conditioner is lower in ambient temperature, and when operation heated (heat pump) pattern, frosting or icing situation can appear in its outdoor heat converter, reduce heating effect, and it is not smooth to occur the drain pan water outlet easily, and the situation that causes freezing occurs.When serious even may cause the fan of outdoor heat exchanger to be frozen in the ice body, fan electromotor burns out, and situations such as fan blade fragmentation take place, and influence the reliability service of air-conditioner greatly.At this situation, some manufacturer has done a little improvement, prevent the draining device that freezes as the off-premises station that discloses a kind of air-conditioner among the Chinese patent literature CN1719144A, be provided with gas-liquid separator and compressor on the centre above the chassis of the casing inside of the off-premises station of air-conditioner, be provided with outdoor heat converter along the casing periphery, it is characterized in that on the chassis form the drainage channel of groove shape along the neighboring, the bottom surface of running through drainage channel forms osculum; Outdoor heat converter is along the drainage channel setting on chassis, and its lower end is immersed in the drainage channel.Heating the overcooled cold junction of crossing of cold-producing medium that when running flows into from indoor set being provided with on the lower end of outdoor heat converter to make.Though the icing device of draining that prevents of this off-premises station can be alleviated frosting or icing to a certain extent, its result of use is still not ideal enough.
Summary of the invention
Purpose of the present invention aim to provide a kind of simple and reasonable, defrosting effect good, and can effectively prevent to freeze in the drain pan, the band rapid frost melting of long service life and the air-conditioner outdoor unit of antifreeze function, to overcome weak point of the prior art.
A kind of air-conditioner outdoor unit by this purpose design with rapid frost melting and antifreeze function, comprise outdoor heat converter, be provided with the frost prevention heat exchanger below its architectural feature outdoor heat converter, one end of assisted capillary that is connected in parallel and magnetic valve communicates with the distributor of outdoor heat converter, and its other end communicates with an end of frost prevention heat exchanger.
Be provided with the anti-freeze heat exchanger below the described frost prevention heat exchanger, an end of anti-freeze heat exchanger communicates with the other end of frost prevention heat exchanger.
Described anti-freeze heat exchanger is arranged in the drain pan.
The assembly one end communication chamber outer heat-exchanger that constitutes by magnetic valve and assisted capillary parallel connection among the present invention, the other end is communicated with frost prevention heat exchanger and anti-freeze heat exchanger, by the duty of control magnetic valve and assisted capillary, be implemented in the different efficacies under refrigeration or the heating mode.When refrigeration mode was worked, the frost prevention heat exchanger was as the super cooled sect of outdoor heat converter, to promote refrigeration; When heating mode was worked, the frost prevention heat exchanger effectively prevented the frosting of outdoor heat converter surface, and the quickly defrosting during defrosting.The anti-freeze heat exchanger directly is connected after the frost prevention heat exchanger, when refrigeration mode is worked, also as super cooled sect usefulness, can further promote refrigeration; When heating mode is worked, mainly play the defrosting water and the interior undischarged defrost water of drain pan on heating clamber outer heat-exchanger surface, guarantee that the defrost water in the drain pan flows out smoothly, prevent drain pan frosting or icing, thereby prolong the service life of off-premises station.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1, the air-conditioner outdoor unit of this band rapid frost melting and antifreeze function, comprise outdoor heat converter 1, be provided with frost prevention heat exchanger 5 below the outdoor heat converter, or it is a part of U pipe below the off-premises station heat exchanger 1 is independent as frost prevention heat exchanger 5, an assisted capillary 3 that is connected in parallel and an end of magnetic valve 4 communicate with the distributor 2 of outdoor heat converter 1, and its other end communicates with an end of frost prevention heat exchanger 5.Be provided with anti-freeze heat exchanger 6 below the frost prevention heat exchanger 5, the anti-freeze heat exchanger is arranged in the drain pan, and an end of anti-freeze heat exchanger 6 communicates with the other end of frost prevention heat exchanger 5.
Control and the refrigerant flow direction of the present invention under different working modes is respectively:
1) refrigeration mode: open magnetic valve 4, refrigerant flows to and is: H-F-E-D-C-B-A;
2) heating mode: close magnetic valve 4, refrigerant flows to and is: A-B-C-D-E-G-H;
3) heating and defrosting pattern: open magnetic valve 4, refrigerant flows to and is: H-F-E-D-C-B-A.
