The outlet Jing triple valves of water-cooled condenser and reheater condenser are connected with reservoir in this patent, due to evaporimeter Rational height maintains an equal level or higher with the height of water-cooled condenser and reheater condenser, and condensed liquid refrigerant is in gravitional force Under the influence of be difficult by pipeline stream easily cause in evaporimeter, in this case cold-producing medium accumulate in water-cooled condenser with In reheater condenser, and pass through the setting of reservoir so that cold-producing medium can be first flowed in reservoir, it is to avoid lime set is cold in water-cooled Accumulate excessive in condenser and reheater condenser, expand the heat exchange area of water-cooled condenser and reheater condenser, improve heat exchange efficiency; When Load Evaporator increases, required cold-producing medium is also more, now cold-producing medium can be fed by reservoir, conversely, load subtracts Hour, unnecessary cold-producing medium can be stored in reservoir, flexibly refrigeration, and adaptability is good;Reservoir is prevented from excessive system Cryogen flows out from condenser, it is to avoid produce liquid hammer to compressor.
Further, the outlet of the reheater condenser is connected by magnetic valve with liquid reserve tank.
When air is after evaporimeter, required heating amount be less or when need not heat, triple valve close its with again The interface of reheater condenser connection, but while cold-producing medium in avoid reheater condenser accumulates excessive, pressure is excessive, now can lead to The opening and closing of control magnetic valve is crossed, cold-producing medium is imported in reservoir, alleviate the pressure in reheater condenser, strengthen reliability.
Further, the triple valve is three-way control valve.
The three-way control valve can adjust the refrigerant flow ratio of reheater condenser outlet and water-cooled condenser outlet, The heating amount of air is adjusted, control accuracy is improved.
Further, also including air cleaner;It is cold that air sequentially passes through in order air cleaner, evaporimeter, reheating Get in after condenser, electric heater, humidifier and pressure fan.
It is miscellaneous by arranging finely ground particles, pollen, bacterium, industrial waste gas and dust that air cleaner is crossed in air filtering etc. Matter, to prevent these impurity from causing damage to air conditioner, additionally it is possible to protect health.
Further, the humidifier be electrode humidifier, electric heating humidifier, dry steam humidifier, wet-membrane humidifier or High-pressure micro mist humidifier.
The humidifier can be according to the selection of air particular/special requirement, and flexibility is high.
Further, first pressure switch is provided with the inlet ductwork of the compressor.
If inlet ductwork hypotony, illustrate that air conditioner there occurs failure, compressor pressure ratios can be caused to increase, load Increase, and then cause compressor damage.The first pressure switch can be used to detect whether manifold pressure is too low, and then be opened and closed Inlet ductwork is protected to air conditioner.
Further, second pressure switch is provided with the export pipeline of the compressor.
If export pipeline hypertonia, illustrate that air conditioner there occurs failure, also compressor load can equally increased, enter And compressor may be damaged.The second pressure switch can be used to detect whether manifold pressure is too high, and then be opened and closed outlet Road is protected by air conditioner.
Further, it is provided with the first non-return valve on the connecting pipeline between the evaporimeter and compressor.

The first one-way valve for leading to triple valve 15 is provided between the connecting pipeline of the reheater condenser 18 and triple valve 15 19。
The second one-way valve for leading to triple valve 15 is provided between the connecting pipeline of the water-cooled condenser 16 and triple valve 15 17。
The operation principle of the present embodiment, its step is as follows:
Process of refrigerastion:
S1:The liquid refrigerant of low-temp low-pressure after absorption air heat, is vaporized into the steam of high-temperature low-pressure in evaporimeter 112;
S2:After the steam of the suction high-temperature low-pressure of compressor 11, compress it into the steam of HTHP and discharge;
S3:The steam of HTHP is entered in water-cooled condenser 16 and reheater condenser 18 to cooling medium(Air)Heat release, it is cold Coagulate for cryogenic high pressure liquid;
S4:The flow proportional of the outlet of reheater condenser 18 and the outlet of water-cooled condenser 16, low temperature are adjusted by three-way control valve 15 Highly pressurised liquid stream is in reservoir 110;
S5:Cryogenic high pressure liquid flows out from reservoir 110, is low pressure, low temperature liquid, return to step after the throttling of expanded valve 111 S1。
In above-mentioned steps S2, should also check whether the pressure of the steam of suction high-temperature low-pressure is too low before compressor 11, And whether the pressure of the steam of the HTHP discharged is too high, according to the export pipeline and inlet tube that judge control compressor 11 The opening and closing on road.Air handling process:
S1:Air is filtered by air cleaner 24, forms clean air;
S2:The heat of the absorption air of evaporimeter 112, and the water vapour in air is condensed, play the effect of cool-down dehumidification;
S3:Reheater condenser 18 is rejected heat in air, and is evaporated water into air, plays the effect of the humidification that heats up;
S4:Air accurately rises high-temperature through electric heater 21;
S5:Air accurately improves humidity through humidifier 22;
S6:Air delivers to interior by the pressurization of pressure fan 23.
Wherein electric heater 21 can be controlled by multistage regulative mode, it is also possible to be controlled by step-less adjustment mode.
