The utility model discloses an energy-saving greenhouse constant temperature system. The interior of the greenhouse is communicated with the interior of the heat pump unit body to form a circulating air path, when the heat pump unit is in heating operation, hot air in the greenhouse enters the heat pump unit through the first air inlet, the hot air is cooled by the second heat exchanger to form cold air, and the cold air is sent back into the greenhouse under the action of the fan module; when the heat pump unit is in refrigeration operation, cold air in the greenhouse enters the heat pump unit through the first air inlet, the cold air is heated by the second heat exchanger to form hot air, and the hot air is sent back into the greenhouse under the action of the fan module. Meanwhile, through the arrangement of the heating water path, hot water on the upper portion of the water tower is conveyed into the heating heat exchange pipe laid at the bottom of the planting pot for radiation heat exchange, and bottom
