Abstract
An energy-saving central air-conditioning unit comprises a compressor unit and a water cooling tower. A water inlet pipe and a water outlet pipe which are connected with the water cooling tower are connected with the compressor unit; the compressor unit is connected with a water supply pipe and a water return pipe which lead to using places; valves are arranged on the water inlet pipe, the water outlet pipe, the water supply pipe and the water return pipe respectively; water pumps are arranged on the water outlet pipe and the water return pipe respectively; a branch water supply pipe is communicated between the water outlet pipe and the water supply pipe; a branch water return pipe is connected between the water return pipe and the water inlet pipe; and the valves are arranged on the branch water return pipe and the water supply pipe. During a hot season, the branch water supply pipe and the branch water return pipe are closed, so that the compressor unit can operate normally, and cooling for a working place can be guaranteed; and during a cold season, the temperature of the outdoor environment is low, the compressor unit is halted, the branch water supply pipe and the branch water return pipe are opened, so that cooling water circulates between the working place and the water cooling tower and supplies the working place after cooled in the water cooling tower by utilizing the ambient temperature, and cooling for the working place can also be guaranteed.
Description
Technical field
The utility model relates to refrigerating plant, specifically a kind of energy-conservation central air-conditioning unit.
Background technology
For the workplace that the constant temperature requirement is arranged, adopt central air-conditioning to control temperature at present usually.Existing central air-conditioning unit is made up of compressor bank, cooling column, water inlet pipe, outlet pipe, feed pipe and return pipe basically; Water inlet pipe, outlet pipe are connected to and contract between unit and the cooling column, and the field of employment is joined, also led to feed pipe and return pipe and compressor bank.The deficiency that existing this central air-conditioning unit in use exists is: be to guarantee the temperature of workplace, even when outdoor environment temperature is low, and the compressor bank running of still need starting shooting, thereby energy consumption is bigger.
The utility model content
The purpose of the utility model is to provide an energy-conservation central air-conditioning unit, and this central air-conditioning unit can utilize outdoor environment temperature that the workplace is lowered the temperature.
For realizing above-mentioned purpose; The utility model adopts following scheme: energy-conservation central air-conditioning unit, have compressor bank and cooling column, and water inlet pipe that cooling column is connected to and outlet pipe and compressor bank are joined; Compressor bank is connected to towards the feed pipe of field of employment and return pipe; Valve is housed respectively on water inlet pipe, outlet pipe, feed pipe and the return pipe, water pump is housed respectively on outlet pipe, the return pipe, be connected with branch's feed pipe indirectly at outlet pipe and feed pipe; Between return pipe and water inlet pipe, be connected to branch's return pipe, on branch's feed pipe, the branch's return pipe valve be housed respectively.
Visible by such scheme,, than hot season branch's feed pipe, branch's return pipe are closed at weather, compressor bank is run well, can guarantee the workplace is lowered the temperature; When weather colder; When outdoor environment temperature is low, compressor bank is shut down, will prop up feed pipe, branch's return pipe is open-minded; Cooling water is circulated between cooling column and workplace; Utilize environment temperature, make cooling water in cooling column, cool off the back and supply also can guarantee cooling the workplace toward the workplace.Under the state that compressor bank is shut down, can realize energy-conservation, reduction of discharging.
Rational in infrastructure, the dependable performance of the utility model, it can guarantee instructions for use, again can be energy-conservation preferably, and long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
The energy-conservation central air-conditioning unit that the utility model provides; Have compressor bank 9 and cooling column 1; Water inlet pipe 2 that cooling column is connected to and outlet pipe 14 join with compressor bank 9, and compressor bank 9 is connected to the feed pipe 4 and return pipe 8 towards the field of employment, and valve 11, valve 12, valve 10, valve 7 are housed respectively on water inlet pipe 2, outlet pipe 14, feed pipe 4 and the return pipe 8; Water pump 16, water pump 15 are housed respectively on outlet pipe 14, the return pipe 8; Be connected with branch's feed pipe 3 indirectly at outlet pipe 14 and feed pipe 4, between return pipe 8 and water inlet pipe 2, be connected to branch's return pipe 5, valve 13, valve 6 are housed respectively on branch's feed pipe 3, the branch's return pipe 5.
Visible by accompanying drawing,, than hot season branch's feed pipe 3, branch's return pipe 5 are closed at weather, both valve 13, valve 6 were closed, with other valve opens, central compressor group 9 is run well, can guarantee the workplace is lowered the temperature; Colder when weather, when outdoor environment temperature is low, compressor bank 9 is shut down; Valve 12, valve 11, valve 10, valve 7 are closed, will prop up feed pipe 3, branch's return pipe 5 is open-minded, both valve 13, valve 6 were opened; Cooling water is circulated between cooling column 1 and workplace; Utilize environment temperature, make cooling water in cooling column, cool off the back and supply also can guarantee cooling the workplace toward the workplace.
