An air-conditioner unit capable of realizing icing and water cooling relates to an air conditioner unit which can produce air conditioner refrigerating water and can produce ice blocks for ice chilling and solves the deicing problem with high efficiency by utilizing condensing heat when the air-conditioner unit produces ice. The unit comprises a refrigerant loop and a deicing loop. The refrigerant loop comprises a compressor (1), a water accumulation type heat exchanger (2), a water-cooled refrigerant condenser (3), a liquid storage device (4), a filter (5), a first electronic expansion valve (6), a first evaporator (7), a second electronic expansion valve (9), a second evaporator (10) and relevant connection pipes; and the deicing loop comprises a water accumulation type heat exchanger (2), a water pump (11), a first evaporator (7), an ice accumulation barrel (8) and relevant connection pipes. The invention realizes the multifunction of the ice chilling air-conditioner unit, not onlycan independently produce refrigerating water but also can produce the ice blocks under partial load or in the night for purpose of air-conditioner ice chilling, prevents apparatus from being left unused and reduces the primary investment on the refrigerating unit of an air-conditioning system.
Description
technical field [0001] The invention relates to an air-conditioning unit that can realize the production of chilled water for air-conditioning, and can also produce ice cubes for ice storage, and at the same time realize the efficient use of condensation heat to solve the problem of deicing when the unit makes ice, and belongs to the design and manufacture of refrigeration and air-conditioning systems technology field. Background technique [0002] In the design of the central air-conditioning system of a building, the air-conditioning unit is usually selected according to the maximum load. However, with the change of ambient temperature and the change of building usage, in the actual operation process, the building air-conditioning unit is in partial load operation state most of the time, and the phenomenon of large horse-drawn carts appears, which leads to the underutilization of the air-conditioning unit and causes equipment failure. Idle waste. As a result, ice storage...
