Abstract

The utility model discloses an environment system of heat resistance and moisture resistance testing system, which comprises a cooling system, a heating system, a humidifying system, a dehumidifying system and a strip-shaped blower. The environment system has the advantages as follows: the system is used for maintaining constant temperature, relative humidity and flow velocity of air above a measuring subsystem and a thermal protection subsystem, so as to reduce the measuring errors.

Description

The environmental system of wet instrument is led in thermal resistance and the perspire of wet resistance test macro
Technical field
The utility model relates to a kind of thermal resistance and wet resistance test macro, the environmental system of particularly a kind of thermal resistance and wet resistance test macro.
Background technology
Along with the change of expanding economy, growth in the living standard and philosophy of life, people more and more pay attention to the clothes wearing comfortableness when buying clothes.The clothes comfortableness roughly comprises three aspects: heat wet comfortableness, contact comfort and euphorosia.The wet comfortableness of heat is one of of paramount importance index wherein.We can use the thermal resistance of clothes and wet resistance to come the wet comfortableness of the heat of clothes is tested and estimated.
For this reason, needs are a kind of can be to the instrument that thermal resistance/wet resistance test of textile material under specific environment.But the current domestic greatest problem that faces is the complete dependence on import of needed tester, costs an arm and a leg.
At present, thermal resistance and wet resistance test macro adopt the hot dish method of perspiring to come thermal resistance/wet resistance is tested usually.The hot dish method of perspiring also claims the skin model method.Hot looping test method is that a kind of test simulation that is used for is close to the device of the heat and moisture transfer process that skin takes place.From test philosophy, the hot looping test method of perspiring belongs to heat of evaporation transfger impedance method, is to be used to measure the impedance (water vapour impedance be meant the steam pressure difference of fabric divided by barometric gradient direction unit are total heat of evaporation flow) of dissimilar fabrics to steam.Evaporative resistance is high more, and the respiratory of fabric is poor more; Evaporative resistance is low more, and then the vapor pervious performance is good more, and what perspire hot dish method test in other words is that heat of steam is transmitted resistance.
When measuring wet the resistance, on porous electric heating breadboard, cover to breathe freely but fluid-tight film, film is passed through with the form of water vapour in the water evaporation back that enters electric hot plate, so there is not aqueous water contact sample, the same porous with breadboard of hot retaining ring upper surface also covers to breathe freely but fluid-tight film, and can keep identical constant temperature, after sample is placed on the film, the evaporation latent heat of breadboard can only scatter and disappear by sample, after the heat of evaporation flow by sample reaches stable state, measure the wet resistance of calculating sample by sample evaporation heat radiation thermal power that process consumed and steam pressure difference.
When measuring thermal resistance, sample is covered on the electric heating breadboard, breadboard and can both keep identical constant temperature with the hot retaining ring (baffle) of bottom on every side is so that the heat of breadboard can only scatter and disappear by sample; The air of surrounding environment can be parallel to specimen surface and flow.After the heat flow of the sample of flowing through reaches stable state, measure the thermal resistance of calculating sample by the thermal power that consumed in the sample heat radiation process and the sample two sides temperature difference.
Temperature, relative humidity and the flow velocity of air is constant above this appliance requires experimental bench.
The temperature of the common air of mensuration system in the market, relative humidity and flow velocity fluctuation are bigger, and measured thermal resistance/wet resistance data exist than mistake.
Summary of the invention
At above shortcoming, the utility model provides a kind of novel environmental system.
In order to overcome above-mentioned deficiency, technical solution adopted in the utility model is:
The environmental system of a kind of thermal resistance and wet resistance test macro, comprise cooling system, evaporimeter, heater, humidification system and strip blower fan, described cooling system comprises temperature sensor, compressor, water pump and the evaporimeter that is connected with water tank, the arrival end of evaporimeter is connected with water pump, and described humidification system comprises ultrasonic wave part and hot saturated part.
The beneficial effects of the utility model: said system is used to keep temperature, relative humidity and flow velocity constant of the top air of measurement subsystem and hot protected subsystem, reduces measure error.
Description of drawings
The schematic diagram of Fig. 1, the utility model cooling system.
The schematic diagram that Fig. 2, the utility model environment are made.
The specific embodiment
See also its implementation process of description of drawings:
The environmental system of a kind of thermal resistance and wet resistance test macro (wet instrument is led in perspire), comprise cooling system, evaporimeter 15, heater 3, humidification system and strip blower fan 5, described cooling system comprises temperature sensor 11, compressor 12, water pump 14 and the evaporimeter 15 that is connected with water tank 13, the arrival end of evaporimeter 15 is connected with water pump 14, and described humidification system comprises ultrasonic wave part 41 and hot saturated part 42.
The mode of cooling system by two-stage refrigeration accurately controls environment and makes the temperature of evaporimeter in the case, thereby makes the temperature of environmental cabinet more stable and accurate with humidity.Principle: make the antifreeze coolant-temperature gage of refrigerant of secondary reach suitable temperature by one-level freon refrigeration equipment and (detect antifreeze coolant-temperature gage closed-loop control by a temperature sensor, also can artificially set antifreeze coolant-temperature gage), the antifreeze water of this temperature is made the evaporimeter circulation of case through environment, thereby changes the temperature and the humidity of the fine-tuning environmental cabinet of this water temperature.
Environment is made its principle of case: by calandria to the environment temperature coarse adjustment, by ultrasonic wave to the ambient humidity coarse adjustment.By heat cooling system saturated and shown in Figure 1 environment temperature, humidity fine setting (are passed through the CPU element computing according to temperature, humidity that environmental cabinet requires to reach again, calculate suitable antifreeze water, hot saturation temperature), by the strip blower fan gas of adjusting is sent in the test cabin.
Temperature, the humidity of top air that said system is used to keep measurement subsystem and hot protected subsystem is constant.Employing saturated vapour and ultrasonic wave compensate the air humidity of controlling the sample top of flowing through; Use frequency converter to come wind speed is regulated.
Those skilled in the art's simple replacement and replacing all are within the protection domain of this patent in this area.
