Heating system: 1, the use of far-infrared heating Nichrome wire-speed electric heating; 2, high temperature, low temperature completely independent systems; 3, the temperature control using P I D + S S R co-channel coordinated control system; refrigeration???? System: 1, in order to ensure the chamber for cooling rate and the minimum temperature requirements, the chamber's refrigeration system cascade refrigeration system consisting of imported compressor, the refrigeration system has a reasonable match, high reliability and easy maintenance etc. 2, refrigeration works: a refrigeration cycle are used against the card if the loop, which consists of two isothermal and two adiabatic process, whose process is as follows: adiabatic compression of the refrigerant through the compressor to a higher pressure, consumed work so that the exhaust temperature, after which the refrigerant through the condenser and other places in and around the medium temperature heat exchange medium heat to four weeks. After the refrigerant flows through the shutoff valve adiabatic expansion work, when the refrigerant temperature decreases. Finally, the refrigerant passes through the evaporator isothermal heat from high temperature object, the object to be cooled so that the temperature is lowered. This cycle so as to achieve the purpose of cooling the cycle 3, design application refrigeration system energy regulation technology, an effective treatment can guarantee but also on energy and cooling capacity of the refrigeration system carried out under the normal operation of the refrigeration unit effective regulation, the refrigeration system operating costs down to a more economical status Nanjing high and low temperature heat chamber energy-efficient design: In addition to fully consider the safety of refrigeration units, high-efficiency use of all sectors, but while taking multiple energy saving measures : such as: refrigeration system cooling capacity adjustment, liquid-gas bypass regulation, evaporation temperature regulation, at any point of constant low temperatures, without heating balance, operating power can be reduced to half, so that operating costs and failure rates refrigeration system decreases to more economical status. Expansion of the use of intelligent automatic conversion system load automatically adjust the refrigerant flow + intelligent electric power data value (%) to match heating and cooling (load) Automatic analog output data output value based. This design than conventional designs can be saving more than 30%. Temperature control output by the microcomputer calculus, to achieve high precision and high efficiency power efficiency. Note: Be sure to choose the time according to their test needs refer to the following points: ⒈ temperature range: The temperature range of the number of devices, you can refer to the highest minimum temperature value ⒉ gentle cycle functions: whether the device has a temperature of circulation, namely: repeatedly to cycle between the temperature curve cycle. ⒊ humidity range: whether the device with humidity function ⒋ heat load: Many electronic product testing will be energized test, in the case of power, the product being tested may have a fever, this will lead to the load. So sometimes buy back the equipment, such as the standard is 20 degrees, but the temperature does not drop down to the last is for this reason, we must keep up with the manufacturer's instructions load. ⒌ handling equipment: Refer to the device's dimensions, location and equipment final arrangements cases, such as door size, dimensions and other stair lifts. ⒍ Power: Refer to device size laboratory electrical power is consistent with the final placement or satisfied.
