Abstract
The utility model discloses a center air conditioning system which can freely provide living hot water during the cooling. A compressor is communicated with a wind cooling condenser and an evaporation heat exchanger through a four-port valve which is communicated with the wind cooling condenser and the evaporation heat exchanger through a throttling device, and the pipe between the wind cooling condenser and the evaporation heat exchanger is provided with a converting electromagnetic valve and a cooling heat exchanger. The living water tank is communicated with the cooling heat exchanger through valves A1 and A2, the sewage water tank is communicated with the cooling heat exchanger through valves B1 and B2, the underground water is communicated with the cooling heat exchanger through valves C1 and C2, and the indoor water tank is communicated with the evaporation heat exchanger. The utility model provides the living hot water through the heat generated during the cooling of the air conditioner, thus having the function of waste heat recollection. The utility model not only avoids the waste of the heat but also is very convenient for the use of the high-temperature water by the users.
Description
Technical field
The utility model belongs to the central air-conditioning technical field, and free domestic hot-water's central air conditioner system can be provided during particularly a kind of the refrigeration.
Background technology
In present most of commercial building, hotel and the part residential building central air-conditioning is installed all, be used for freezing summer and getting winter dim, brought an office and a living environment as snug as a bug in a rug to everybody, but a large amount of heat energy that the central air-conditioning unit of prior art is produced have been wasted when refrigeration.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides the central air conditioner system that a kind of heat energy that utilizes the central air-conditioning unit to be produced provides free domestic hot-water when refrigeration.
The technical scheme that the utility model adopted is: can provide free domestic hot-water's central air conditioner system to comprise compressor 1, cross valve 2, air-cooled condenser 3, cooling heat exchanger 4, evaporating heat exchanger 5, conversion electromagnetic valve 6, throttling arrangement 7 during refrigeration; Compressor 1 is communicated with air-cooled condenser 3 and evaporating heat exchanger 5 respectively by cross valve 2, and air-cooled condenser 3 and evaporating heat exchanger 5 are communicated with cross valve 2 by throttling arrangement 7; Pipeline between air-cooled condenser 3 and the throttling arrangement 7 is provided with conversion electromagnetic valve 6 and cooling heat exchanger 4; Water supply tank is communicated with cooling heat exchanger 4 by valve A1, A2; The used heat water tank is communicated with cooling heat exchanger 4 by valve B1, B2; Underground water is communicated with cooling heat exchanger 4 by valve C1, C2; Room water tank and evaporating heat exchanger 5 are communicated with.
The beneficial effects of the utility model are: the heat energy that effectively utilizes the central air-conditioning unit to be produced when refrigeration provides free domestic hot-water, has the function of Waste Heat Recovery.The utility model has not only been avoided the also very user-friendly hot water of the waste of heat energy.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
The specific embodiment
Free domestic hot-water's central air conditioner system when providing a kind of the refrigeration, the utility model can be provided, in structured flowchart shown in Figure 1, this system comprises compressor 1, cross valve 2, air-cooled condenser 3, cooling heat exchanger 4, evaporating heat exchanger 5, conversion electromagnetic valve 6, throttling arrangement 7; Compressor 1 is communicated with air-cooled condenser 3 and evaporating heat exchanger 5 respectively by cross valve 2, and air-cooled condenser 3 and evaporating heat exchanger 5 are communicated with cross valve 2 by throttling arrangement 7; Pipeline between air-cooled condenser 3 and the throttling arrangement 7 is provided with conversion electromagnetic valve 6 and cooling heat exchanger 4; Water supply tank is communicated with cooling heat exchanger 4 by valve A1, A2; The used heat water tank is communicated with cooling heat exchanger 4 by valve B1, B2; Underground water is communicated with cooling heat exchanger 4 by valve C1, C2; Room water tank and evaporating heat exchanger 5 are communicated with.
Operation logic
During refrigeration: cold-producing medium is carried by cross valve 2 by compressor 1 and is got back to compressor 1 by cross valve 2 again through behind cooling heat exchanger 4, throttling arrangement 7 and the evaporating heat exchanger 5.
If the room water tank temperature does not reach design temperature, and water supply tank is when having reached design temperature, conversion electromagnetic valve 6 begins conversion automatically, and cold-producing medium is carried by cross valve 2 by compressor 1 and got back to compressor 1 by cross valve 2 again through behind air-cooled condenser 3, throttling arrangement 7 and the evaporating heat exchanger 5.
Conversion electromagnetic valve 6, cooling heat exchanger 4 are controlled by the temperature controller in the water supply tank automatically with the conversion of air-cooled condenser 3.
When heating: cold-producing medium is carried by cross valve 2 by compressor 1 and is got back to compressor 1 by cross valve 2 again through behind evaporating heat exchanger 5, throttling arrangement 7 and the air-cooled condenser 3.
When using the used heat water tank, can extract heat from the spent hot water, cold-producing medium is carried by cross valve 2 by compressor 1 and is got back to compressor 1 by cross valve 2 again through behind evaporating heat exchanger 5, throttling arrangement 7 and the cooling heat exchanger 4.
If underground water is abundanter, open valve C1, C2, valve-off A1, A2 and B1, B2, this unit just become source, tableland heat pump hot water or cold water unit.
