Abstract

The invention discloses a heat-pump device of a closed type ice-storage air conditioner. The heat-pump device is characterized by comprising an ice-slurry and cold-water heat pump unit, a pressure-bearing type energy storage tank, a solution pump, user-end equipment, a circulating pump and heat-source-end equipment which are connected to form an energy-saving air-conditioning device. The heat-pump device disclosed by the invention has the advantages that the average installed capacity can be less than that of the conventional air-conditioning device by about 57%, the average investment can be lower than that of the conventional air-conditioning device and the operating cost can be lower than that of the conventional air-conditioning device; the functions of refrigeration, cold storage, ice melting and cold release of the air conditioner can be realized without using a primary pump and an intermediate heat exchanger; the heat-supply and heat-storage functions of the heat pump can be realized by utilizing various heat sources; and in addition, the heat-pump device also has a function of heat recovery for supplying sanitary hot water.

Description

technical field [0001] The invention relates to an organic combination of ice slurry chiller (or ice slurry chiller with four-way valve), pressure-bearing energy storage tank, solution pump, user end equipment, circulation pump, heat source end equipment, valves, pipe fittings, etc. An integrated closed ice storage air conditioning heat pump device. Background technique [0002] The air-conditioning devices commonly used in the world today determine the installed capacity according to the maximum load on the design day, and most air-conditioning objects have large load changes within a day and have a long no-load period. According to statistics, the 24-hour average load of these air-conditioning objects is only about 43% of the peak load (see attached Figure 8 ), so that only about 57% of the installed capacity is idle on the design day, which is an astonishing "waste". [0003] At present, there is no new type of air conditioner in the world that has an average investment...
