The invention discloses pressure pump refrigeration equipment which comprises a control unit which is configured to enter an energy-saving control mode when the outdoor environment temperature reaches the lower limit value of a preset energy-saving control threshold value; in the energy-saving control mode, the pressure ratio is obtained in real time; when the obtained pressure ratio reaches the lower limit value of a preset fan shutdown threshold value, the outdoor fan is controlled to stop running; when the obtained pressure ratio reaches the upper limit value of a preset fan shutdown threshold value and reaches the lower limit value of a preset pressure ratio range, the rotating speed of the outdoor fan is controlled to be reduced or the stopped outdoor fan is controlled to be restarted; when the obtained pressure ratio is within the preset pressure ratio range, the current rotating speed of the outdoor fan is kept, and energy adjustment is conducted on the pressure pump unit; and when the obtained pressur
