Cooling and heating integrated laboratory equipment

The sixth generation of cooling and heating equipment is the laboratory has been further improved on the basis of the fifth generation of the product, closer to the true commercial products in the structure and function. The air conditioning can be divided into two parts, the first part is the simulation of the indoor unit, behind the simulation outdoor unit, indoor unit condenser was further improved housing transparent shell, full-function remote control, micro motor control open throttle, automatically send cold air, Heating, making the product more perfect, intuitive. Fridge on the basis of the fourth generation has been improved, in front of the freezer, the studio behind the refrigerator compressor. Installation of automatic temperature control device temperature regulator, can set the desired temperature. Maximum features: 1, full set of equipment become more real, full-function remote control. 2, easy to use, intuitive and strong, beautiful appearance. 3, increasing experimental project design, and circuit portion fault presentations together. 4, the circuit part of the fault point is provided with fault indicator and fault switch codes. The main technical parameters: Power supply: AC220V ± 5% 50Hz Total power consumption :: <1KW Dimensions: 1600mmX800mmX1170mm Compressor Power: Air conditioning: 1ph Refrigerator: 1 / 10ph refrigerants: Air conditioning: R22 refrigerator: R12 Heating: Electric heating (adjustable) split air-conditioning circuit common faults pilot projects: one, the machine does not work or does not work properly, you can demonstrate the following breakdown: 1, microprocessor damage, fault codes Q, should be replaced with 2, bad crystal, the fault code I 3, CPU work a + 5V supply is lost, the fault code G 4, rectifier diode damaged and can not work properly, the fault code F 5, 7812 three-terminal regulator is bad, does not work properly, the fault code V 6, CPU malreduction, air conditioning can not be work, fault code H II indoor fan operation, and the host does not work, you can troubleshoot the following ways: 1. The compressor does not work, under normal circumstances: Capacitor overload protection circuit, overload can replace the capacitor 2, The control instruction is wrong, the fault code K 3, such as 12V power is lost, the fault code V
