Abstract

The utility model discloses a decoupling-control-based humidifier for a calibrated room type calorimeter. The humidifier comprises a tank body and a tank cover which is matched with the tank body in a sealed way. A heating device is arranged in the tank body. The tank body also comprises an inner container which is arranged in the tank body. A gap between the inner container and the tank body forms a heat-preservation cavity. According to the calibrated room type calorimeter for an air conditioner, time for stabilizing a working condition can be prolonged by an intercoupling relationship between dry bulb temperature and wet bulb temperature, and by the humidifier, the aim of shortening the time for stabilizing the working condition is fulfilled. A solution is that: the humidifier is subjected to heat-preservation treatment as much as possible to eliminate influence on the dry bulb temperature during the humidification of the humidifier and make a humidification process become a thermostatic humidification process. The problem of influence on the dry bulb temperature of air when the wet bulb temperature is adjusted by the humidifier is solved, and the aim of shortening the time for stabilizing the working condition is fulfilled.

Description

Demarcation type room calorimeter based on the humidifier of separating idol control
Technical field
The utility model relates to the development& testing field of air-conditioner, relate in particular to demarcation type room calorimeter based on the humidifier of separating idol control.
Background technology
Air-conditioner room type calorimeter is divided into: Balanced Ambient Room Type Calorimeter, demarcation type room calorimeter.
Air-conditioner demarcation type room calorimeter laboratory is the higher a kind of method of precision in the household air-conditioner method of testing, but its construction cost is also higher, and especially required to reach the thermally equilibrated cycle longer its when test, and cause the test run cost also high.
Air-conditioner demarcation type room calorimeter laboratory brief principle and structure thereof are shown in Figure of description 1.The main purpose of laboratory is the running environment (mainly being meant the dry-bulb temperature of air, indoor operating mode, the outside operating mode that wet-bulb temperature all reaches setting) that simulates air-conditioner, tests out each item index of air-conditioner under this working condition then: the refrigerating capacity of air-conditioner, energy consumption etc.
Laboratory is made up of indoor 2, outside 4, tested air-conditioning 3, air reprocessor group 5 (each of indoor, outside), wet-and-dry-bulb thermometer probe tube 1 (each of indoor, outside).Air reprocessor group 5 is made up of cooler 6, electric heater 7, humidifier 8, blower fan 9.
The indoor operating mode is regulated by the air reprocessor group 5 of indoor.The outside operating mode is regulated by the air reprocessor group 5 of outside.
Below only with its test philosophy of test specification of the inboard refrigerating capacity of air conditioner chamber.Utilize the operating mode of the air reprocessor group 5 of indoor 2 and outside 4 respectively with indoor operating mode, outside regulating working conditions to standard-required.Under standard condition, the refrigerating capacity of tested air conditioner 3 (energy that it is taken away from the indoor) is to confirm through the energy that mensuration is used for the refrigerating capacity of balance tested air conditioner and indoor that moisture removal is imported 2.Obviously, during test, indoor 2, outside 4 all will reach the specified standard operating mode and be stabilized in this operating mode; Promptly require dry-bulb temperature, the wet-bulb temperature of indoor 2, outside 4 all will reach standard-required value and stable.
The adjustment process of air reprocessor group 5 is following: 6 pairs of air of cooler cool off and dry.7 pairs of air of electric heater are heated, and the dry-bulb temperature of air is promptly regulated by the power of electric heater 7, and its control is accomplished by dry-bulb temperature controller (not drawing among the figure).The wet-bulb temperature of air is regulated by the power of the humidifier electrothermal tube in the humidifier 8, and its control is accomplished by wet-bulb temperature controller (not drawing among the figure).
When the dry-bulb temperature of air changed, its wet-bulb temperature also had the variation of corresponding non-linear relation, and this is the enthalpy by air---moist matter decision.When regulating wet-bulb temperature, because humidifier itself also can distribute heat, so the dry-bulb temperature of air also has the variation of corresponding non-linear relation.This shows that dry-bulb temperature, wet-bulb temperature are coupled together each other, when regulating one of them amount, the another one amount also can produce corresponding change.
It is elongated that the mutual coupling relation of dry-bulb temperature, wet-bulb temperature will make operating mode reach stable time.How reducing operating mode, to reach the stable time be that those skilled in the art hope the technical problem that solves very much.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art, provide demarcation type room calorimeter based on the humidifier of separating idol control, reduce operating mode and reach the stable time.
The utility model is realized through following technical proposals:
Demarcation type room calorimeter based on the humidifier of separating idol control, comprise casing and the case lid that is sealed and matched with it, electro-heat equipment is installed in the casing, said casing also comprises an inner bag that sets within it, the gap formation incubation cavity between inner bag and the casing; Be provided with heat-insulation layer in the said incubation cavity.
Said case lid is provided with vapour-discharge tube; Said vapour-discharge tube is coated with heat-insulation layer.
Said casing also is provided with water inlet pipe; Said casing and case lid flexibly connect.
Solution of the present invention is that humidifier is incubated processing as far as possible, eliminates humidifier influence to dry-bulb temperature when humidification; Make humidification become the isothermal humidification process.
After humidifier was incubated processing, during humidifier work, the wet-bulb temperature of air can change with the power of the humidifier electro-heat equipment in the humidifier.Simultaneously, because the heat-blocking action of heat-insulation layer, its influence to the dry-bulb temperature of air will diminish; Increasing the thickness of heat-insulation layer, make its influence little to ignoring, according to the enthalpy of air to the dry-bulb temperature of air---moist matter, this moment, humidification then became the isothermal humidification process.
The control of humidifier is accomplished by wet-bulb temperature controller (not shown).
Compared with prior art the beneficial effect of the utility model is:
The utility model has solved humidifier when regulating wet-bulb temperature to the problem that influences (because be the isothermal humidification process, so can think that its dry-bulb temperature to air do not have influence when the utility model scheme was regulated wet-bulb temperature) of the dry-bulb temperature of air.Though to the problem that influences of the wet-bulb temperature of air, the utility model has still reached the purpose that obvious minimizing operating mode reaches stable time when solve regulating dry-bulb temperature.
It is consistent reliable that the utility model provides, and degree of regulation is high, and technological means is simple and easy to do, and the ground part that is skillfully constructed has solved the coupling problem of dry-bulb temperature, wet-bulb temperature in the prior art, reduces the purpose that operating mode reaches stable time thereby reached.
