Detailed Description
The machine room cooling unit integrated with the fluorine pump shown in fig. 1 and 2 integrates the V-shaped condenser, the liquid storage device and the fluorine pump together, and the fluorine pump does not need to be separately placed at another position, so that the space is saved.
As shown in fig. 1 and 2, the fluorine pump-integrated machine room cooling unit includes a V-shaped condenser 1 disposed on a support frame 7, such as but not limited to a square, and connected in sequence, an accumulator 3 vertically disposed on one side of a refrigerant outlet end of the V-shaped condenser 1, and a fluorine pump 2 horizontally disposed in front of the refrigerant outlet end of the V-shaped condenser 1.
The vertically placed liquid accumulator 3 and the horizontally placed fluorine pump 2 are respectively arranged on one side and the front part of the refrigerant outlet end of the condenser 1, and the space of the V-shaped side of the V-shaped condenser 1 is utilized, so that the whole structure is compactly arranged.
The condensation liquid pipe of the V-shaped condenser 1 reaches the refrigerant outlet after being converged by the heat exchanger pipelines on the two sides, and then is communicated with the inlet of the liquid storage device 3 through the first branch pipe 61, and the refrigerant outlet of the condenser 1 is consistent or basically consistent with the inlet of the liquid storage device 3 in height, so that the first branch pipe 61 is short in length and does not need to be bent when horizontally arranged, and the manufacturing cost is saved.
The outlet of the reservoir 3 is opposite and level with the inlet of the fluorine pump 2 and communicates through a third branch 63, which third branch 63 may thus be a short straight pipe.
The outlet of the fluorine pump 2 is connected with the indoor unit through a fifth branch pipe 66, so that natural heat exchange or compressor refrigeration heat exchange is realized.
The refrigerant flowing into the liquid reservoir 3 is easily affected by temperature and turns into gas, and the fluorine pump 2 is easily damaged due to the phenomenon that the refrigerant cannot be pumped by the fluorine pump 2. In order to solve this problem, in some embodiments, a second branch pipe 62 connected in parallel with the accumulator 3 is provided between the inlet and the outlet of the accumulator 3, and the refrigerant discharged from the refrigerant outlet of the V-shaped condenser 1 directly enters the second branch pipe 62 and is pumped away by the fluorine pump 2; when the refrigerants converging into the first branch pipe 61 are more, one part of the refrigerants enter the second branch pipe 62, the other part of the refrigerants enter the liquid storage device 3 to be stored, the arrangement greatly reduces the air suction phenomenon caused by the refrigerants which cannot be sucked by the fluorine pump 2, the equipment loss is reduced, and the operation cost is saved.
In consideration of high outdoor temperature in summer, the control of the temperature in the machine room cannot be realized only by indoor and outdoor heat exchange, and the compressor needs to be started for refrigeration. In some embodiments, a fourth branch pipe 64 which is communicated with the inlet and the outlet of the fluorine pump 2 is connected beside the inlet of the fluorine pump 2, a check valve 65 which prevents the outlet of the fluorine pump 2 from flowing to the inlet through the fourth branch pipe 64 is arranged on the fourth branch pipe 64, when the compressor needs to be started in summer, the fluorine pump 2 is closed, and the refrigerant in the third branch pipe 63 is guided into the machine room through the fourth branch pipe 64 and is refrigerated by the compressor; in order to save electric energy in winter, when the compressor is closed and the fluorine pump 2 is turned on, the pressure at the outlet of the fluorine pump 2 is higher than that at the inlet of the fluorine pump 2, so that the check valve 65 is in a closed state, and the refrigerant in the third branch pipe 63 can only be pumped by the fluorine pump 2 and cannot pass through the fourth branch pipe 64.
In other embodiments, a liquid viewing mirror 31 is further disposed on the tank body of the liquid reservoir 3, so as to facilitate observation of the amount of the refrigerant stored in the liquid reservoir 3. In some embodiments, the upper end of the reservoir 3 is further provided with a safety valve 32, and when the pressure in the reservoir 3 is too high, the safety valve 32 opens to release a part of the pressure to ensure the safety of the reservoir 3.
In some embodiments, an electric cabinet 4 is disposed at one end of the V-shaped condenser 1, and includes a pressure sensor, a temperature sensor and a controller, wherein the controller is used for controlling the fluorine pump 2 to operate, the pressure sensor collects the pressure at the inlet and the outlet of the fluorine pump 2, the temperature sensor collects outdoor temperature information, and the controller controls the fluorine pump 2 to stop when the pressure difference between the inlet and the outlet exceeds a set pressure value. The outdoor temperature collected by the temperature sensor is low, for example, the controller controls the fluorine pump 2 to be started when the temperature is below 5 ℃, and the compressor stops running. When the outdoor temperature is higher than 5 ℃, the controller controls the fluorine pump 2 and the compressor to operate simultaneously, mixed refrigeration is realized, and the energy efficiency ratio of the air conditioner is improved. When the outdoor temperature is higher than 20 ℃, the operation of the fluorine pump is stopped, and the compressor continues to operate to realize mechanical refrigeration. According to the change of the outdoor temperature, the controller controls the compressor/the fluorine pump to operate in different operation modes, so that the aim of saving energy to the maximum extent is fulfilled.
In some embodiments, the support frame 7 comprises a first layer of support frame 71 for supporting the condenser 1, a second layer of support frame 72 disposed below the first layer of support frame 71 for supporting the fluorine pump 2 and the liquid storage device 3, wherein the first layer of support frame 71 and the second layer of support frame 72, four columns 73 and a top portion 74 together form the support frame 7.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
