The specific embodiment
Below cooperate preferred embodiment graphic and of the present utility model, further setting forth the utility model is to reach the technological means that predetermined utility model purpose is taked.
Referring to shown in Figure 1, constant temperature air conditioning device of the present utility model comprises a compressor 10, a condenser 20, a radiating tube 30, an expansion valve 40, an evaporimeter 50 and a triple valve 60, wherein:
These radiating tube 30 bendings are set around the side of this evaporimeter 10;
One input of this compressor 10 is with an output of this evaporimeter 50 of a pipeline connection, one output of this compressor 10 is communicated with an input of this condenser 20 and an input of this radiating tube 30 respectively with two pipelines, the pipeline that is communicated with this compressor 10 and condenser 20 is provided with a filter 12, this filter 12 can be used to filter the impurity in the refrigerant, the pipeline that is communicated with this compressor 10 and radiating tube 30 is provided with one first check valve 11, this first check valve 11 can be magnetic valve, it is mainly used to control this refrigerant and can only be flowed towards radiating tube 30 by this compressor 10, and whether this first check valve 11 also can switch between opening and closing, allow this cryogen flow to this radiating tube 30 with control;
This triple valve 60 is communicated with an output of this condenser 20 respectively with three pipelines, one output of this radiating tube 30 and an input of this evaporimeter 50, this triple valve 60 can be magnetic valve, it is used for controlling this refrigerant and flows into this expansion valve 40 by this condenser 20 and radiating tube 30 through this triple valve 60, and the part that refrigerant flows in these triple valve 60 inner control radiating tubes 30 can be switched between opening and closing, whether allow this refrigerant flow into this expansion valve 40 through this triple valve 60 with control by radiating tube 30, in addition, the pipeline that is communicated with this triple valve 60 and condenser 20 is provided with a drier 61 and one second check valve 62, this drier 61 can be used to remove the moisture in this refrigerant, this second check valve 62 is located between this drier 61 and the triple valve 60, this second check valve 62 all is unidirectional unlatching under general state, and being mainly used to control this refrigerant can only be flowed towards this triple valve 60 by this condenser 20.
When above-mentioned constant temperature air conditioning device of the present utility model operates, under general situation, the part that refrigerant flows in this first check valve 11 and this triple valve 60 inner control radiating tubes 30 is closed simultaneously, at this moment: this compressor 10 sucks compressor 10 inside with the refrigerant of high-temperature gas in the evaporimeter 50, cause evaporimeter 50 internal pressures to reduce, and under compressor 10 effects, the increased pressure of this refrigerant, simultaneous temperature also improves; Then, the gaseous refrigerant of this HTHP flows into this condenser 20 via this filter 12, the high-pressure liquid refrigerant that transfers normal temperature by means of the cooling effect of this condenser 20 to, and this normal temperature high voltage liquid cryogen flow to this expansion valve 40, inflow evaporator 50 after expansion valve 40 throttlings and step-down via this drier 61, second check valve 62 with triple valve 60 more in regular turn; The liquid cryogen of this normal temperature low pressure absorbs extraneous a large amount of heat and transfers gaseous state to by liquid state in this evaporimeter 50, make the temperature on these evaporimeter 50 surfaces drop to extremely low, the air blast (not shown) of being located at these evaporimeter 50 1 sides blows the Cryogenic air around the evaporimeter 50 towards the space of desiring to lower the temperature, thereby reduce the temperature in this space, allow the user in this space feel cool and comfortable.
After the temperature in the above-mentioned space of desiring to lower the temperature drops to a low-temperature values of presetting, the part that refrigerant flows in above-mentioned first check valve 11 and this triple valve 60 inner control radiating tubes 30 is just opened, make part flow in this radiating tube 30 via this first check valve 11 by the HTHP gaseous refrigerant that this compressor 10 flows out, and then the temperature of this radiating tube 30 that raises; At this moment, on the one hand, owing to this air blast can blow Cryogenic air around this evaporimeter 50 and the high temperature air around this radiating tube 30 simultaneously towards this space of desiring to lower the temperature, so can avoid the temperature in this space to continue to reduce; On the other hand, flow through this radiating tube 30 HTHP gaseous refrigerant can these triple valve 60 places with together flow into again in this expansion valve 40 after normal temperature high voltage liquid cryogen by 20 outputs of this condenser mixes, because this HTHP gaseous refrigerant cools off without this condenser 20, therefore with the temperature raising that can make this normal temperature high voltage liquid cryogen after this normal temperature high voltage liquid cryogen mixes, thus, when mixed cryogen flow is to this evaporimeter 50, just can't effectively bring into play the usefulness that it absorbs ambient heat, so the temperature of evaporimeter 50 surrounding airs also can raise a little, continue to reduce further to avoid the temperature in this space.
Afterwards, treat that temperature in this space is increased to a default high temperature values after, just can close the part that refrigerant flow in first check valve 11 and this triple valve 50 inner control radiating tubes 30 once more, to recover the cooling effect at these evaporimeter 50 places.
Rely on aforesaid design, the compressor 10 of constant temperature air conditioning device of the present utility model need not to switch to continually opens or closes, just can reach the effect of control indoor temperature, so this compressor 10 can keep the state of continuous running, the not frequent switching of reason and out of order situation generation.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
