Abstract
The utility model relates to an evaporator comprising a radiation sheet and a conveyor can which can be communicated with the radiation sheet, wherein the conveyor can is provided with a return gas pipe and an input distributor from top to bottom; the conveyor can is provided with at least two conveyor distributors, each conveyor distributor is communicated with the conveyor can by a conveyor distributor pipe bundle, and an antiseptic layer is coated on the surface of the radiation sheet. Refrigerant passing by the evaporator has stable velocity of flow, stable degree of superheat and controllable flow rate.
Description
Technical field
The utility model relates to a kind of evaporimeter.
Background technology
Sea-freight always is exactly one of very important mode of transportation, and along with industry and the becoming increasingly prosperous of economic trade, the boats and ships transportation interchange between the various countries is also frequent day by day, and steamer navigates by water several months and even 1 year at sea continuously also becomes quotidian ordinary affair.The food and the continuous equipment that turns round that carry with ship all need refrigeration plant, all need heating equipment with the cold climate area in the winter time, and therefore, air-conditioning is one of indispensable key equipment in the boats and ships running.
Compression-type refrigeration is a refrigeration plant the most frequently used in the air-conditioning system, and compression-type refrigeration mainly is made up of four kinds of refrigeration parts, and they are compressor, condenser, expansion valve and evaporimeter.Its principle is to utilize the characteristic of the evaporation heat absorption of cold-producing medium, condensation heat release to reach the refrigeration purpose, make just that cold-producing medium compresses in equipment such as compressor, condenser, expansion valve and evaporimeter, heat release, throttling, four main thermal processions of heat absorption, finish kind of refrigeration cycle.
The effect of evaporimeter is to make the high pressure liquid refrigerant that comes out from condenser become low-pressure liquid behind expansion valve, enter in the evaporimeter evaporation heat absorption and become the low pressure gaseous state, enters in the compressor then.
In small-type refrigeration appliances such as refrigerator, air-conditioner, capillary commonly used is made throttling arrangement, it mainly be by the size of its caliber and length control liquid refrigerant flow so that evaporimeter can under suitable situation, work.About general title internal diameter 0.5～2mm, the copper tube of length about 1～4m is capillary in the Refrigeration Engineering.Comparing capillary is that no movement parts can not worn and not torn and is difficult for leakages, low price easy to manufacture, installation and saves trouble with expansion valve as the advantage of throttling arrangement, and to be that flow is little can not arbitrarily artificially adjust shortcoming at any time.
Liquid refrigerant absorbs heat in evaporimeter, and to flash to the heat that gas absorbs be the degree of superheat to compressor suction, and the degree of superheat is big, and the refrigerant temperature that enters compressor is too high, causes the compressor internal temperature too high, is easy to generate phenomenons such as shutdown; Evaporimeter has a feed flow circulation line again, and wherein the flow of cold-producing medium and flow velocity can't change according to the variation of compressor and expansion valve, and compressor life-span, pressure of inspiration(Pi), pressure at expulsion and refrigerating capacity are had considerable influence.
The utility model content
The purpose of this utility model provides the evaporimeter that a kind of disengagement area can change along with compressor refrigerating capacity, the expansion valve liquid supply rate changes and change, and cold-producing medium is stable through the flow rate of liquid of this evaporimeter, the degree of superheat is stable, and flow is controlled.
For achieving the above object, the utility model is taked following design:
A kind of evaporimeter, comprise fin and the transfer pot that is connected with fin, this transfer pot is provided with muffler and input distributor from top to bottom, described transfer pot is provided with two conveying distributors at least, each carries distributor to be connected with transfer pot by carrying the distributor tube bank, the other end is connected with an expansion valve, the quantity of described feed pipe is determined according to compressor energy adjustment gear, by following different numbers, the expansion valve of model connects, change cold-producing medium and carry the distributor tube bank through evaporimeter, make area of dissipation and expansion valve, compressor adapts to, and reaches balance, helps the normal operation of whole refrigeration system; Described fin surface applies one deck anticorrosive coat, strengthens the resistance to corrosion of evaporimeter.
Described anticorrosive coat is acrylic resin modified.
Described evaporimeter internal duct is a T2 deoxidation copper tube.
The utlity model has following advantage:
The utility model according to compressor energy adjustment gear a plurality of conveying distributors is set and the corresponding distributor of carrying is restrained, make according to the needs of compressor and expansion valve the pipeline of the different disengagement areas of low pressure refrigerant inflow evaporator of carrying from expansion valve, change corresponding endotherm area thus, make the degree of superheat stable; By controlling the switch of corresponding expansion valve front end magnetic valve, control the evaporimeter endotherm area, when guaranteeing that the refrigeration mechanism cold changes arbitrarily, evaporimeter return line flow velocity unanimity guarantees the refrigeration system flow speed stability.

The specific embodiment
Embodiment
As shown in Figure 1, a kind of evaporimeter described in the utility model, comprise fin 1 and the transfer pot 2 that is connected with fin 1, this transfer pot 2 is provided with muffler 3 and input distributor from top to bottom, as shown in Figure 2, described transfer pot 2 is provided with two conveying distributors 4,5, described conveying distributor 4 is connected with transfer pot 2 by conveying distributor tube bank 7, described conveying distributor 5 is connected with transfer pot 2 by conveying distributor tube bank 8, the other end of described each conveying distributor is connected with the input of an expansion valve, and the output of expansion valve is connected with the input pipe of carrying distributor.Two distributor institute traction disengagement areas that evaporimeter is provided with are respectively 1/3 and 2/3.By the switch of preceding two magnetic valves of control expansion valve, change the evaporimeter endotherm area, thereby endotherm area and expansion valve, compressor are adapted to, help the normal operation of whole refrigeration system.
Claims (3)
