Abstract
The utility model relates to an inverter manual environmental chamber, which comprises a chamber body, an operation chamber inside the operation chamber, a temperature and humidity modulation chamber and a bottom chamber; wherein, a refrigeration, temperature preservation, and wetness system constructed by a condenser, a compressor, an evaporator, a circulation fan, a heating tube and a temperature moisture sensor are positioned in the temperature and moisture modulation chamber and the bottom chamber, a humidifier is connected with temperature and moisture modulation chamber via a steam supply tube, the compressor for refrigeration and wetness is adopted by the inverter compressor controlled by the inverter controller. The utility model adopts the intelligent inverter controller to adjust the inverter compressor turning speed automatically, ensuring the constant of the temperature and humidity inside the operation chamber, the high precise control of the temperature and humidity inside the controlling chamber is achieved, and because the compressor realizes stepless speed variation, lowering the noise, saving the energy and overcoming the shortcoming that the compressor is allowed to re-started after the compressor stops for three minutes.
Description
Technical field
The utility model be a kind ofly be used for germination, grow seedlings, plant culture, tissue cultivation, insect and multi-purpose growth cabinets such as toy raising, aging of product test.
Background technology
The present domestic interior wet type growth cabinet that removes that has all adopts fixed frequency formula refrigeration compressor, in whole refrigeration and dehumidification process, the rotating speed of compressor is fixing nonadjustable, (total power) opened at full speed, or closes, and keeps the constant of growth cabinet temperature inside and humidity with this.But adopt this fixed mode frequently to have very big defective: for keeping the temperature inside the box and humidity switch refrigeration compressor as far as possible continually, and at every turn all can the additive decrementation much electricity between the open and close machine, open too continually the service life that compressor can shorten compressor because of dash current simultaneously.Moreover common fixed formula compressor frequently just needs start again after shutdown, must delay time more than 3 minutes, but in this 3 fens clock times, temperature and humidity might be gone up significantly, causes the fluctuation of temperature and humidity and influences control accuracy.Full speed running during simultaneously because of work, because inertia very easily causes the excessive of refrigeration and dehumidifying, must heat or add water this moment, caused the waste of energy and water.Invariable frequency compressor can only be worked in the voltage range about 220V, the time regular meeting can not work because of low-voltage.In order to solve the moisture fluctuation problem in the above-mentioned serial problem; the patent No. is that " ZL00242694.3 " " removes the wet type growth cabinet " in the shunting; adopted the way that on evaporimeter, adds baffle plate; moisture fluctuation problem when solving 3 minutes inner compressor stoppage protections after dehumidifying, but this kind method is to reach the purpose that reduces the moisture fluctuation value to sacrifice the actual heat exchange effective area of evaporimeter.The minimizing of the actual heat exchange effective area of evaporimeter means the reduction of refrigerating efficiency, and the energy consumption increase, has influenced the dynamic relevant art index of climate box because of cooling rate slows down simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the defective and the deficiency of the growth cabinet of above-mentioned employing invariable frequency compressor, designs a kind of have fast-refrigerating, superpower dehumidifying, energy-conservation, long service life, the growth cabinet of temperature, intellectuality control that the humidity control accuracy is high.This growth cabinet comprises operating room, temperature, humidity regulation chamber and the Lower Hold in casing, the casing, the refrigeration be made up of condenser, compressor, evaporimeter, circulating fan, electrothermal tube, temperature, humidity sensor is housed in temperature, humidity regulation chamber and Lower Hold, system is incubated, preserves moisture, humidifier is connected with temperature, humidity regulation chamber by steam transmitting pipe, the compressor of refrigeration of the present utility model, dehumidifying usefulness adopts frequency-changeable compressor, and the output of frequency-variable controller is connected with this frequency-changeable compressor; Described frequency-variable controller can be nested in the master controller, also can be installed in outside the master controller, and its input and master controller output join, and output and frequency-changeable compressor join; Described frequency-changeable compressor can be AC induction motor, also can use dc brushless motor.The utility model adopts the intelligent frequency-conversion controller to regulate the frequency-changeable compressor rotating speed automatically, thereby regulate the machine operate power, move with peak power during beginning, reach design temperature rapidly and set humidity, turn down the speed of compressor then rapidly, and keep a low-down rotating speed, to keep the constant of temperature and humidity, avoided compressor to open, stop causing neglecting of the temperature inside the box, humidity high, low suddenly like this, to reach the purpose of temperature, humidity in the high accuracy control cabinet because of frequent.Because compressor operation has been realized infinitely variable speeds, has really realized soft start, soft stop not only can reduce noise greatly, and energy-saving effect is remarkable, does not have the so-called back compressor just allows starting after three minutes the problem of shutting down.
