Abstract

The utility model relates to a cold storage air conditioning system combining external ice melting and water cold storage, which relates to the technical field of air conditioning. The brine circuit of the present invention includes a dual-working-condition refrigerator, an ethylene glycol pump P1, a cold storage coil and an electric valve V2 connected in sequence. The connecting pipeline of the glycol pump P1 and the cold storage coil is connected with the water outlet of the cold source side of the glycol plate heat exchanger, and the connecting pipeline of the dual-working condition refrigerator and the electric valve V2 is connected with the glycol plate heat exchanger The water inlet on the cold source side is connected. The cooling circuit of the present invention includes a cold water plate heat exchanger, an upper section water distributor and a lower section water distributor. The water outlet on the cold source side of the cold water plate heat exchanger is connected to the water distributor on the upper section, and the water distributor on the lower section is connected to the water inlet on the cold source side of the cold water plate heat exchanger. The other side of the glycol plate heat exchanger and the cold water plate heat exchanger are respectively connected to the water inlet and outlet of the user side. The invention can not only meet the requirements of the low-temperature air supply system, but also solve the problem of incomplete ice melting, enhance the cascaded utilization of cooling capacity, and further reduce the operating cost.

Description

Technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cold storage air conditioning system that combines external melting ice and water cold storage. Background technique [0002] With the rapid economic development, my country's power demand is increasing, and the contradiction between insufficient peak power supply and excess trough is becoming increasingly prominent. The current electricity consumption situation in modern cities is that the electricity load has increased sharply in the summer because the operation of a large number of air-conditioning systems takes up a large amount of load. According to statistics, the power consumption of the air-conditioning system accounts for about 40% to 50% of the total energy consumption of buildings, while the power consumption of air-conditioning in large and medium-sized cities accounts for more than 30% of the city's total power supply. Therefore, the air-conditioning power loa...
