Abstract
The invention relates to a lateral air supply and return treatment cabinet layout of a refrigerator safety performance testing room and a method thereof. The lateral air supply and return treatment cabinet layout of the refrigerator safety performance testing room comprises an air treatment cabinet and an environmental test chamber, wherein the air treatment cabinet is arranged on a side face of the environmental test chamber; the environmental test chamber is provided with a master air supply pipe and a master air return pipe which are symmetrically arranged up and down; and the master air supply pipe and the master air return pipe are connected with an air outlet and an air inlet of the air treatment cabinet respectively. The method comprises the following steps of: allowing air to flow through a coil pipe of the air treatment cabinet under the action of a fan in the air treatment cabinet; matching an evaporation coil pipe of the air treatment cabinet with an automatic control electric heating pipe for use to control air outlet temperature; distributing air to each air supply branch pipe after the air flows through the master air supply pipe; uniformly supplying the air into the environmental test chamber through an air supply perforated plate; gathering the ventilated air to the master air return pipe through air return branch pipes; and allowing the air to flow through the coil pipe in the air treatment cabinet to adjust temperature so as to finish circulation. Compared with the prior art, the layout and the method solve the problem of site limitation and meet the requirements of temperature, humidity and air speed inside the testing room at the same time.
Description
Technical field
The present invention relates to a kind of refrigerator testing laboratory air blow and return air-treatment cabinet, be specifically related to the air blow and return air-treatment cabinet layout of testing laboratory in the household electric refrigerator safety efficiency integrated test system and the method for wind speed profile thereof.
Background technology
At present the operating condition of test of conventional refrigerator testing laboratory is controlled to be by the air blow and return air-treatment cabinet that is installed in vertical tip exterior central authorities and realizes.The requirement that this method can the guarantee test indoor temperature and humidity, wind speed profile reaches GB/T 8059 " family expenses refrigerating appliance " series standard.Promptly realize that at the width symmetric configuration referring to Fig. 1,2 examples: air-treatment cabinet 1, the header pipe 2, return air house steward 6, environmental test chamber 7, orifice plate 8.Go up header pipe 2 through air-treatment cabinet 1 top to the comprehensive orifice plate 8 in refrigerator environment laboratory 7 tops environmental test chamber's 7 chamber interior of blowing.The reason that this layout designs is widely adopted is that the uniformity of the humiture field of refrigerator laboratory inside and wind speed profile is controlled easily and reached.But, when having determined for the length of refrigerator laboratory and width, the length direction of refrigerator laboratory adds when the width dimensions of air blow and return air-treatment cabinet can not satisfy fixed size condition, can only satisfy its symmetric configuration mode by the station quantity that reduces refrigerator to be measured.So separate the problem that never possesses the refrigerator performance test chamber that maybe can not satisfy length same as described above of construction under the usual conditions situation and width.
Summary of the invention
The present invention will provide a kind of refrigerator security performance test cabinet side air blow and return air-treatment cabinet layout and method, for the deficiency of air-treatment cabinet symmetric configuration under the restrictive condition that overcomes the place.
For achieving the above object, technical scheme of the present invention is: a kind of refrigerator security performance test cabinet side air blow and return air-treatment cabinet layout, comprise the air-treatment cabinet, and the environmental test chamber is characterized in; The air-treatment cabinet is installed in the side, environmental test chamber, and the upper and lower symmetric arrangement in environmental test chamber is sent, the return air house steward, and give, the return air house steward goes out with the air-treatment cabinet respectively, air inlet connects.
Send, return house steward and air-treatment cabinet and go out, be connected with between the air inlet give, the return air arm.Blowpipe is provided with the air-supply orifice plate.
Be provided with evaporation coil and automatic control electric heating tube in the air-treatment cabinet, and evaporation coil and automatic control electric heating tube are used.
A kind of refrigerator security performance test cabinet side air blow and return air-treatment cabinet wind speed profile method, at first air is flow through its coil pipe by the fan action in the air-treatment cabinet, evaporation coil and automatic control electric heating tube through the air-treatment cabinet are used, control air leaving air temp, air is behind the header pipe, be assigned to each blowpipe, evenly air is sent in the environmental test chamber by the air-supply orifice plate, circulation of air is after the return air arm is aggregated into the return air house steward, and then the coil pipe that flows through in the air-treatment cabinet carries out adjustment, finishes circulation.
The invention has the beneficial effects as follows:
The present invention is installed in the side, environmental test chamber with the air-treatment cabinet, and symmetric arrangement is carried out in the air channel of sending back to of refrigerator laboratory inside.Air passes through the comprehensive orifice feeding in top behind the air delivery duct.By increase give, the return air arm overcome that the sidewall air supply windage increases and problem of uneven distribution.Big and unaccommodated problem that this design has solved not only that the space is insufficient, and can reach the national standard requirement that refrigerator chamber interior longitudinal temperature gradient distribution＜1K/m and wind speed＜0.25m/s distributes, provide the artificial environment experimental technique a kind of new air blow and return layout designs.
The present invention can reduce the restriction to site condition by at laboratory's side arrangement air-treatment cabinet, on limited longitudinal length, arranges more test station.By the design of header pipe, blowpipe, air-supply orifice plate, overcome the big problem of side air-conditioning cabinet air-supply windage, the guarantee test room air is even, and temperature, wind speed satisfy standard-required.
The present invention the invention solves the problem of place restriction compared with prior art, and the humiture that also can satisfy inside, laboratory simultaneously requires and the wind speed requirement.
