Abstract
The utility model relates to a device capable of adding enthalpy and defrosting through jetting vapor, including a compressor, a condenser, a throttling component and an evaporator. The parts above are connected orderly to form a loop; and the exit end of the compressor is connected with the entrance end of the evaporator through a pipeline which is provided with an electronic expanding valve. When the evaporator is defrosting, the electronic expanding valve opens a certain angle, and high temperature air of certain quantity enters the evaporator so as to add enthalpy, make the temperature of the evaporator increase and realize the aim of defrosting. In the defrosting process, the machine is not required to stop running, so that the working time is not reduced, moreover, no energy is wasted and the service life of the machine set is not affected.
Description
Technical field
The utility model belongs to a kind of heat-exchanger rig, especially refers to a kind of defroster of air-conditioning.
Background technology
Existing air-conditioning heat transfer device comprises compressor, cross valve, condenser, restricting element and evaporimeter, Fig. 1 is existing air-conditioning heat transfer device schematic diagram, with reference to Fig. 1, compressor 1 links to each other with evaporimeter 4 with condenser 3 by cross valve 2, restricting element 5 is between condenser and evaporimeter, whole system constitutes a loop, can realize the heat exchange function that the loop is inside and outside.During long-term the use, on evaporimeter, can form frost.Existing Defrost mode is, at first with compressor shutdown, cross valve is made as oppositely, and start then makes hot fluid flow into evaporimeter, removes the frost on the evaporimeter.Shut down then, cross valve is reverted to forward, continue start work again.This Defrost mode will be wasted a lot of energy, and the multiple switching machine will reduce the life-span of unit.
The utility model content
A purpose of the present utility model is to solve weak point of the prior art, and a kind of new Defrost mode is provided, and does not need to shut down when defrosting, can not waste a large amount of heats.
For achieving the above object, air injection enthalpy-increasing defroster of the present utility model comprises compressor, condenser, restricting element and evaporimeter, each part mentioned above connects and composes the loop successively, and links to each other with the arrival end of evaporimeter by pipeline at the port of export of compressor, and is provided with valve on pipeline.
Preferably, described valve is an electric expansion valve.
To evaporator defrost the time, electric expansion valve is opened certain angle, a certain amount of high-temperature gas is entered in the evaporimeter, evaporimeter is increased enthalpy, the temperature of evaporimeter is improved, reach the purpose of defrosting.
When defrosting, need not to shut down, can not reduce the working time, can not waste energy, can not influence the life-span of unit.
Description of drawings
Fig. 1 is existing air-conditioning heat transfer device schematic diagram.
Fig. 2 is an air injection enthalpy-increasing defroster schematic diagram described in the utility model.
The specific embodiment
Fig. 2 is an air injection enthalpy-increasing defroster schematic diagram described in the utility model, with reference to Fig. 2, compressor 1, condenser 3, restricting element 5 and evaporimeter 4, connect and compose the loop successively, and the port of export at compressor 1 links to each other by the arrival end of pipeline with evaporimeter 4, and on pipeline, be provided with electric expansion valve 6, when to evaporimeter 4 defrostings, electric expansion valve 6 is opened certain angle, a certain amount of high-temperature gas is entered in the evaporimeter 4, evaporimeter is increased enthalpy, the temperature of evaporimeter is improved, reach the purpose of defrosting.
Claims (2)
1. air injection enthalpy-increasing defroster, comprise compressor, condenser, restricting element and evaporimeter, each part mentioned above connects and composes the loop successively, it is characterized in that: the port of export of compressor links to each other with the arrival end of evaporimeter by pipeline, and is provided with valve on pipeline.
