Title:
MULTIPLE HEAT-SOURCE MULTI-HEAT PUMP SYSTEM CAPABLE OF PERFORMING AIR-HEAT-SOURCE COLD-STORAGE OPERATION AND SIMULTANEOUS WATER-HEAT-SOURCE COLD-STORAGE AND THERMAL-STORAGE OPERATION, AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2019/027085
Kind Code:
A1
Abstract:
The present invention relates to a multiple heat-source multi-heat pump system which can switch between air-heat-source cold-storage operation and simultaneous water-heat-source cold-storage and thermal-storage operation even without using a four-way valve, and a method for controlling the same and, more specifically, to a multiple heat-source multi-heat pump system which can perform air-heat-source cold-storage operation and simultaneous water-heat-source cold-storage and thermal-storage operation, and a method for controlling the same, whereby both an air-cooling-type condenser and a water-cooling-type condenser are employed in a single device and can be connected to a first and a second valve separate from each other to allow selective use of the condensers, so that the single device can have both a thermal-storage function and a cold-storage function, and can perform a selective on/off control of the first and the second valve and an automatic switching control according to a compression ratio, an inflow water temperature, or an outdoor temperature, without requiring a four-way valve for switching of use between the cold-storage and the thermal-storage and without stopping a compressor at a low compression ratio.
