Description
Technical field
The present invention relates to a kind of dehumidification control method of the air-conditioning with the PCT electric heater, belong to room air and regulate the field.
Background technology
The air that humidity is bigger not only makes the people feel wet vexed, uncomfortable, also can cause heavy corrosion to building and ornament.
In air conditioner refrigerating when operation,, room air runs into the extremely low evaporimeter of temperature and condensation becomes water droplet, the principle of Here it is existing air conditioner dehumidification.Therefore, existing air-conditioning will reach the dehumidifying purpose, when promptly under dehumidification mode, moving, will inevitably cause indoor temperature to descend, and this just is difficult to satisfy as needing the requirement of constant temperature dehumidification under the situation such as tealeaves preservation.
PTC (Positive Temperature Coefficient; Be called for short PTC; Positive temperature coefficient) material is the semiconductor resistor that a kind of typical case has temperature sensitivity, and when surpassing certain temperature (Curie temperature), its resistance value is along with the rising of temperature is increasing of step evolution.
The PTC electric heater has utilized the above-mentioned positive temperature characterisitic of ptc material exactly, and promptly when reaching uniform temperature value (curie point), its resistance raises suddenly, makes electric current decline power reduction, reaches the purpose of automatic constant-temperature.Therefore, the PTC electric heater can overheated, not produce naked light, receives the influence of voltage pulsation little, safe in utilization energy-conservation, is used on the firing equipment more and more.
The PTC electric heater is used for the assistant heating of air-conditioning, can thoroughly solve the common air-conditioning winter severe cold and heat a not enough difficult problem season.The heat pump system of PTC electric heater and air-conditioning is warm to be system fully independently, and they are actually to work alone separately and are independent of each other, and just start simultaneously.When ambient temperature is low excessively the air-conditioner air outlet temperature is crossed when low, air-conditioning provides warm braw through the heating of PTC electric heater.
The air-conditioning of band PCT electric heater can guarantee that air-conditioning is crossed in outdoor temperature and start as usual, heats rapidly when low.Because the appearance of extremely cold weather in recent years, the air-conditioning of band PCT electric heater is very universal.
Summary of the invention
The invention reside in the problem that causes environment temperature to descend when solving air conditioner dehumidification.
For this reason, the invention provides a kind of dehumidification control method of the air-conditioning with the PCT electric heater.Gather when air-conditioning moves under dehumidification mode and comparison indoor coil pipe TE and indoor environment temperature TA, and monitor the operation conditions of compressor, outdoor fan, indoor fan, PCT electric heater and control its method of operation.
Among the present invention, when TS+2 ℃ of indoor environment temperature TA >=air-conditioning design temperature, compressor, outer blower fan move continuously, and indoor fan is opened operation.When meeting the following conditions simultaneously, open the PCT electric heater: indoor fan operation>=1min;<48 ℃ of indoor coil pipe TE; PCT electric heater shut-in time>=1min.
In the dehumidification control method of the present invention, at the simultaneously suitable opening electric heater of dehumidifying, thereby the thermal loss that makes dehumidifying bring is able to replenish through electric heater, thereby reaches the purpose of constant temperature dehumidification.
If outdoor environment temperature is when very low, as below 10 ℃, during this moment air conditioner dehumidification operation, indoor coil pipe also can be very low (48 ℃), this moment, the air-conditioning leaving air temp also can be very low, needs this moment the PTC electrical heating to open, the raising heating capacity.If outdoor environment temperature is when higher, as 10 ℃ on the upper side the time, this moment, indoor coil pipe was higher, and during greater than 48 ℃, the air-conditioning leaving air temp is higher, and need not open the PTC electrical heating this moment.The PTC electric heater is high-power energy dissipation device, so unnecessaryly under dehumidification mode open, increase kwh loss always.The PTC electric heater is opened when the heating capacity of air-conditioning is very poor, when heating capacity is high, closes, and can make air-conditioning effectively energy-conservation like this.
After indoor fan is opened under the dehumidification mode, and move 1min continuously, the rotating speed the when slow-speed of revolution is steadily to normal operation when letting indoor fan from startup; Because the PTC electric heater is a heater members, environment temperature is very high after opening, and caloric requirement produces air quantity through the blower fan rotation it is blown away.Indoor fan is not opened as if opening at electric heater, and heat is not just in time dissipated, easy heat damage of the working of plastics of air-conditioning even burning.After indoor fan is opened, open electric heater again, the heat that produces when the PTC electric heater is opened can be in time taken away in this control sequence, has promptly increased heat, can make the safer of air-conditioner operation again.
In addition, in the control method of PTC electric heater of the present invention, in the compressor operating process,, then needed to open again behind the 1min if the PTC electric heater cuts out.Like this, can prevent that the PTC electric heater from receiving thermal shock, thereby prolong its life-span.
Among the present invention, during arbitrary condition below satisfying, close the PCT electric heater: air-conditioning is in shutdown or pattern conversion; Indoor fan or compressor do not move; Indoor coil pipe TE＞52 ℃.
Air-conditioning is at heating mode, refrigeration mode, dehumidification mode, opening electric heater not when the conversion of air vent mode isotype is confirmed or during shutdown; Electric heater is in closed condition; Prevent the conversion that the PTC electric heater does not stop at the opening and closing state; Prevent big dash current, effectively protect the PTC electric heater.
When indoor fan fault or indoor fan were not opened, the caloric value of PTC electric heater can not blow away, and the working of plastics to air-conditioning causes damage easily; Should close electric heater this moment, guarantees the safety of air-conditioner.
If outdoor environment temperature is higher, as 10 ℃ on the upper side the time, indoor coil pipe is also higher, and as greater than 52 ℃ the time, the air-conditioning leaving air temp is higher, and the heating capacity of air-conditioning is better, and need not open the PTC electric heater this moment, can make air-conditioning effectively energy-conservation like this.
If electric heater opening and closing temperature spot is identical, can cause indoor coil pipe open and close back and forth when this temperature spot just, be unfavorable for electric heater control.Therefore; Among the present invention; The PTC electric heater needs indoor coil pipe (less than 48 ℃) to need the numerical value of indoor coil pipe (greater than 52 ℃) different when cutting out with the PTC electric heater when opening; A return difference control is arranged when the opening and closing of PTC electric heater like this, more effectively control the operation of PTC electric heater.
In addition; After indoor temperature transmitter, indoor coil pipe sensor damage, can not monitor temperature the time, also should close the PTC electric heater, prevent that the PTC electric heater from opening; Satisfy not exit criteria (indoor coil pipe>50 ℃), caused the PTC electric heater to be opened always.Like this, even indoor temperature sensor, indoor coil sensor are bad, also to control the PTC electric heater effectively.
The present invention is as further improving, and<during TS+2 ℃ of air-conditioning design temperature, compressor, outdoor fan leave 10min and stop 6min as air-conditioning design temperature TS≤indoor environment temperature TA; Indoor fan is closed in compressor cuts out 3min, and indoor fan moves with faint wind under other situation; When meeting the following conditions simultaneously, open the PCT electric heater: compressor accumulative total operation>=30min; Compressor, outdoor fan and indoor fan are simultaneously in operation; During arbitrary condition below satisfying, close the PCT electric heater: the PTC electric heater is opened 8min; Air-conditioning is in shutdown or pattern conversion; Indoor fan or compressor do not move; Indoor coil pipe TE＞52 ℃.
Like this; When air conditioner dehumidification, suspend the operation (compressor, outdoor fan leave 10min and stop 6min) of compressor, outdoor fan, suitably opening chamber's inner blower changes wind; Opening electric heater comes additional heat under proper condition simultaneously, thereby accomplishes constant temperature dehumidification.
< during air-conditioning design temperature TS, compressor, outer blower fan are out of service, and inner blower brings into operation with faint wind behind 3min out of service, and the PTC electric heater cuts out as indoor environment temperature TA.The wind that changes through indoor and outdoors reaches the purpose to the constant indoor temperature dehumidifying fully.
