First-time rendering of the air conditioning indoor and outdoor machine works fully analytical

We all know that air conditioning is used to making a home appliances and warm, and the root of the principle, many of my friends are certainly did not know.

Today, edit it for everyone to bring more air conditioning principle, interested friends don't miss it.

Heating process: the solid line represents the heating State

Heating is the four-way valves open and close State and refrigeration is just the opposite, flows through the order is:

Compressor pressure export via the four-way valves 1---4 to muffle---stop valve (also known as low pressure valves or repair valve)---indoor heat exchanger---back to outdoor machine stop valve (also known as high pressure valve)---capillary-heat exchanger---2-four-way valves-3 to the reservoir fluid---compressor low pressure side.

Outdoor unit of heat exchanger of temperature sensor (thermistor) used for refrigeration, testing the pipe temperature heat exchanger, if elevated temperature anomaly may calculate the pipeline pressure and the temperature anomaly signals to the control panel.

Outdoor-outdoor temperature sensor (thermistor) is mainly used to detect if the outdoor temperature.

Refrigeration processes

Refrigeration time compressor pressure exit after four-way valve 1-2 to the heat exchanger for heat, gradually become superheated steam saturated steam, which in turn become saturated liquid or supercooled liquid.

After cutting through the capillary blood pressure refrigerant liquid (mixed with saturated steam)---to outdoor machine stop valve (also known as high pressure valve) enter indoor heat exchangers (evaporators), evaporation from the surrounding medium heat absorption into gas, refrigeration. During the evaporation process, temperature and pressure of the refrigerant remains unchanged. From the evaporator from the refrigerant has become dry saturated steam or slightly Superheat of superheated steam. Substances from liquid into gas to heat absorption, air conditioning and refrigeration. Indoor air: back to back to the outdoor unit through the trachea cut-off valve (also known as low pressure valves or repair valve) into the silencer--4-4-3-way valve to the compressor and low back to the gas side complete refrigeration cycle.

Analytical laboratory machine works

Indoor heat exchanger temperature sensor (thermistor) detect heat exchanger temperature, such as refrigeration or heating time at one time, heat exchanger temperature can not reach the required temperature of the pipe, the sensor will not normal signal to the Control Panel, such as insufficient or refrigerant in the system without refrigerant, indoor unit tube temperature sensor is not normal, abnormal signal will be sent to the dashboard, the dashboard to stop processing, and thus protect the compressor, avoid high temperature operation of compressor for a long time.

High temperature for a long time because the compressor is very likely to be burned.
