Abstract
The invention discloses a control method of an electric passenger car interior water-cooled air conditioner. The electric passenger car interior water-cooled air conditioner has two working states of refrigeration and heating. The control method of refrigeration and heating includes the steps that in the refrigeration state, ice cubes are placed in an energy-storing and heat-preserving water tank, water in the energy-storing and heat-preserving water tank turns into ice water as the ice cubes melt, an air blower and a water pump are started to enable the ice water to pass through an evaporator in a circulating mode, and cold air generated by the evaporator is blown into a cab of an electric passenger car by the air blower; in the heating state, while the electric passenger car is charged, electric heating tubes work to heat the water in the energy-storing and heat-preserving water tank, when hot air is needed, the air blower and the water pump are started to enable hot water to pass through the evaporator in a circulating mode, and hot air generated by the evaporator is blown into the cab of the electric passenger car by the air blower. The control method of the electric passenger car interior water-cooled air conditioner can prevent the air conditioner from consuming electric energy of batteries of the electric passenger car excessively when the air conditioner works, and thus increases the trip distance of the electric passenger car, reduces the load of the batteries and prolongs the service life of the batteries.
Description
Technical field
The present invention relates to the control method of the indoor water air-conditioning of electrocar.
Background technology
The indoor air-conditioning of the electrocar in current market is that what to adopt is the state-of-the-art DC machine compressor air-conditioning of existing market (air conditioner), and DC machine compressor power consumption is very big, takes very much electricity when work, and its power supply is the battery by electrocar.And the travelled distance of electrocar when starting air-conditioning, must have been shortened like this in the battery major impetus that to be electrocar travel source.Increase the load of battery, also shortened the service life of battery.
In addition, the motorcar air conditioner of all new productions with CFC-12 as refrigeration working medium---dichlorodifluromethane.Dichlorodifluromethane a lot of shortcomings, particularly R12 and R11, their penetrating power is very strong, and gas leakage importantly damages the ozone layer easily, makes ozone layer cause the cavity.It is not only the ozone killer, also is the accomplice of " green-house effect " global alternating temperature, can make that sea level rise.
Summary of the invention
Technical matters to be solved by this invention just provides the indoor water air conditioning control method of a kind of electrocar, avoid air-conditioning work too much to consume the electric energy of electrocar battery by effective and reasonable structure design and method control, avoid the dichlorodifluromethane of air-conditioning discharging to the harm of environment simultaneously.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the indoor water air conditioning control method of electrocar, this electrocar room conditioning comprises evaporator, supply ventilating fan and energy storage attemperater, store hot water or frozen water in the described energy storage attemperater, described energy storage attemperater is connected with the evaporator water inlet by coolant inlet pipe, described coolant inlet pipe is provided with water pump, described evaporator water outlet is connected with the energy storage attemperater by coolant outlet pipe, and described supply ventilating fan is located at evaporator side and air outlet towards evaporator; Be provided with tubular electric heating element in the described energy storage insulation can, described tubular electric heating element is connected with temperature controller, described temperature controller control tubular electric heating element break-make;
The indoor water air-conditioning of this electrocar has refrigeration and heats two mode of operations, freezes and the control method that heats is:
At refrigerating state, close the tubular electric heating element switch, in the energy storage attemperater, place ice cube, the interior water of energy storage attemperater became frozen water when ice cube melted, open the switch of supply ventilating fan and water pump, start supply ventilating fan and water pump and make ice water circulation pass through evaporator, the cold wind that evaporator produces blows into electrocar operator's compartment by supply ventilating fan;
Under the state of heating, when electrocar charges, the other tubular electric heating element socket of setting up of electrocar 220V charging socket also connects power supply, water in the electrocar charging in the tubular electric heating element work heating energy storage attemperater, water temperature up to the energy storage case reaches 90 degrees centigrade, this moment is under the control of temperature controller, cut off electrothermal tube power, tubular electric heating element is quit work, when the needs hot blast, open supply ventilating fan and pump switch, start supply ventilating fan and water pump and make hot water circulation pass through evaporator, the hot blast that evaporator produces blows into electrocar operator's compartment by supply ventilating fan.
Preferably, be provided with sluicing valve bottom the described energy storage insulation can.
Preferably, described energy storage insulation can top is provided with the safety valve with relief function.
Thereby the present invention is flowed in evaporator by the hot water that stores in the energy storage attemperater or cold water and to evaporator blower heat or the cold air that evaporator distributes is blowed to the driver to reach the purpose that heats or freeze by supply ventilating fan.Thereby do not discharge the dichlorodifluromethane that environment is had destructive effect, and its power consumption seldom, have only a water pump doing periodical duty, its power consumption is 1% power consumption of DC machine compressor, can avoid air-conditioning work too much to consume the electric energy of electrocar battery, thereby prolonged the travelled distance of electrocar, reduced the load of the battery of knowing clearly, prolonged the service life of battery.
