Low-temperature refrigerant flow back rapidly rapidly, mix in refrigeration system, pressure balance, low-temperature refrigerant storage in evaporator at this time
It deposits energy and runs through other high temperature refrigerants in pipeline and system and carried out energy exchange, evaporator inner refrigerant storing energy
It dissipates and is scattered and disappeared rapidly, energy fails to utilize;Although passing through the working time energy of extension air-conditioning vaporization cycle blower in the prior art
Portion of energy is obtained, but still has the high and low temperature refrigerant mixing of most of energy in refrigerant systems that heat exchange is caused to make
Energy loss fails to utilize.
Summary of the invention
The object of the present invention is to provide a kind of air conditioner refrigerating surplus energy utility methods, to realize that the refrigeration complementary energy in evaporator is enough
It is utilized to greatest extent by air-conditioning.
In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of air conditioner refrigerating surplus energy utility method, the air-conditioning include passing through piping connection structure by evaporator, compressor, condenser
At refrigeration cycle, and vaporization cycle blower matched with evaporator, it is characterised in that: setting electric expansion valve drives
Dynamic model block and temperature sensor, electric expansion valve access pipeline between condenser and evaporator, and temperature sensor includes air-conditioning sheet
Body is used to monitor the temperature sensor of room temperature, and the temperature sensor that evaporator temperature is monitored at evaporator is arranged in,
Drive module is electrically connected with compressor, vaporization cycle blower, electric expansion valve, each temperature sensor respectively;
Drive module acquires the monitoring signals of air-conditioning own temperature sensor, when the temperature letter of air-conditioning own temperature sensor monitoring
After number reaching air-conditioning set temperature, drive module control compressor stops working, while drive module control electric expansion valve closes
It closes, vaporization cycle blower keeps work to send out the refrigeration complementary energy in evaporator;
Drive module acquires the temperature sensor signal at evaporator, and the temperature sensor signal at evaporator reaches Indoor Temperature
When spending, drive module controls electric expansion valve and opens;Compressor of air conditioner enters standby mode simultaneously, when air-conditioning own temperature senses
When the temperature of device monitoring reaches set temperature, drive module control compressor is reworked.
A kind of air conditioner refrigerating surplus energy utility method, it is characterised in that: the drive module is according to warm at evaporator
Spend the start and stop of sensor signal control vaporization cycle blower.
The method of the present invention by being arranged electric expansion valve in systems, after compressor shutdown, electric expansion valve close and
Compressor collective effect blocks the low-temperature refrigerant completely cut off in evaporator, and vaporization cycle pressure fan keeps work will be in evaporator
Refrigeration waste cold send out;Determine that electric expansion valve is opened by the temperature difference of monitoring evaporator temperature and room temperature, the road Shi Fu system
It is restored balance in system to protect the clean boot next time of compressor, while can also determine that air-conditioning evaporates wind according to this temperature
The start and stop of machine.The method of the present invention compared with the existing technology in by way of the time of fixed air-conditioning draught fan work, in evaporator
Complementary energy enough utilized to greatest extent by air-conditioning.
After automatic mode refrigeration of the present invention is shut down, compressor stops working, while electric-control system sends a signal to driving mould
Block is closed to control electric expansion valve, is completely cut off the low-temperature refrigerant in evaporator and extraneous energy exchange, is reduced in evaporator
Energy scatters and disappears.
The complementary energy of evaporator of the present invention is taken out of by air-conditioning vaporization cycle blower.
The present invention is that the reopening (to guarantee of electric expansion valve is determined by monitoring evaporator temperature and room temperature
The pressure balanced requirement of compressor start next time), it can also the start and stop of temperature control vaporization cycle blower accordingly as needed.
Beneficial effects of the present invention:
1, the method for the present invention is simple, reliable.
2, the complementary energy in evaporator is enough is utilized by air-conditioning to greatest extent, makes full use of the energy.
3, the present invention can be achieved that now air-conditioned repacking can be widely applied.
Detailed description of the invention
Fig. 1 is the method for the present invention schematic diagram.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1, a kind of air conditioner refrigerating surplus energy utility method, air-conditioning includes by evaporator 3, compressor 6, condenser 7
Electronic expansion is arranged in the refrigeration cycle being made up of piping connection, and vaporization cycle blower 4 matched with evaporator 3
Valve 1, drive module 2 and temperature sensor, electric expansion valve 1 access pipeline between condenser 7 and evaporator 3, temperature sensor
It is used to monitor the temperature sensor of room temperature including air-conditioning itself, and is arranged at evaporator 3 and monitors evaporator temperature
Temperature sensor 5, drive module 2 are electric with compressor 6, vaporization cycle blower 4, electric expansion valve 1, each temperature sensor respectively
Connection;
Drive module 2 acquires the monitoring signals of air-conditioning own temperature sensor, when the temperature of air-conditioning own temperature sensor monitoring
After signal reaches air-conditioning set temperature, drive module 2 controls compressor 6 and stops working, while drive module 2 controls electronic expansion
Valve 1 is closed, and vaporization cycle blower 4 keeps work to send out the refrigeration complementary energy in evaporator 3;
