Fan coil thermostat steam pressure type
fan coil thermostat steam pressure type
action of bellows in spring, spring tension is controlled by a knob on the panel, the capillary on the air conditioner indoor air suction FengKouChu, react to the indoor cycling return air temperature. When the room temperature rising to the setting temperature, thermal dose of gas expansion of capillary and bellows, bellows elongation and overcome the spring tension connected the switch contact, the compressor operation, refrigeration system, until the room temperature and fell to the set temperature, the heat pack gas contraction, corrugated pipe shrinkage action with spring and puts switch off position, make the compressor motor circuit is cut off. This action repeatedly, so as to achieve the goal of control room temperature.
electronic temperature controller, Resistive) Is using the resistance method to measure the thermal, generally USES the white gold, copper, tungsten, and semiconductor ( Thermistors, etc. ) As the temperature resistance, the resistance of each has its optimum point. Most of central air conditioner hvac thermostat sensor based on thermal resistance type.
thermistor type fan coil thermostat is made according to the principle of wheatstone bridge. On both ends of BD E the power is connected, according to the kirchhoff's law, as the bridge of the resistor R1 * R3 and R4 = R2 potential of two points A and C are equal, the output end there is no current flows through the between A and C, the impedance of the thermal resistor R1 vary with ambient temperature increase or decrease the size of the change, the balance is damaged, between the AC output current. Therefore, when a thermostat, can easily by selecting the appropriate thermistor to change the temperature adjusting range and working temperature.
thermostats hvac expansion valve, as the name suggests, find extensive use in ac compressor control valve institutions. Since hvac expansion valve has become much dependent on technology in today's world, there is wide use of such motor operated valve.
Zhuhai Edison Smart Home Co., Ltd. attaches great importance to customers and assists them in achieving their demands.
When you choose to buy instead of ac compressor control valve, the money you save may allow you to buy multiple other necessities, more than you had initially planned on buying.
Zhuhai Edison Smart Home Co., Ltd., which prides itself on wireless thermostat for applying in different ways.
