Claim 3:
4. A control method of a waterway two-way valve of the precooler-based transcritical CO2 heat pump system of claim 1, comprising:
during a normal heating process, closing a waterway bypass valve (3), and opening the waterway two-way regulating valve (4), the system inlet water being divided into two parts through the three-way diversion valve (2); a first part of the system inlet water being heated after flowing through the precooling system condenser (22), and flowing through the three-way confluence valve (5) to the water outlet (6); a second part of the system inlet water being cooled by the precooling system evaporator (24) first, then entering the CO2 gas cooler (12) of the CO2 heat pump system to be heated again, and flowing through the three-way confluence valve (5) and converging with a first circulating water and being supplied to the water outlet (6).
