The invention discloses an air source cold and hot water heat pump system, which relates to the technical field of heat pumps, and aims to solve the problem of high investment cost of the existing air source cold and hot water heat pump system and the accelerated heating capacity of the system when the outdoor heat exchanger is frosted. Invented for the problem of attenuation. The air source cold and hot water heat pump system is under the heating condition, when the liquid level of the liquid falling to the bottom of the casing is lower than the oil return hole, and when the liquid level is higher than the oil return hole and the height of the oil return hole When the difference is less than the preset value, the mass of the liquid flowing through the oil return hole per unit time is less than the mass of the liquid contained in the to-be-separated matter entering the shell per unit time; When the height difference of the hole reaches the preset value, the mass of the liquid flowing through the oil return hole per unit time is equal to the mass of the liquid contained in the to-be-separated material entering the housing per unit time. The invention is used to absorb heat from the air to produce hot water.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to an air source cold and hot water heat pump system. Background technique [0002] refer to figure 1 and figure 2 , in the existing air source hot and cold water heat pump system, since the outdoor heat exchanger 01 is an air-cooled fin heat exchanger, and the indoor heat exchanger 02 is a refrigerant water heat exchanger, the heat transfer coefficient of the indoor heat exchanger 02 It is much larger than the heat transfer coefficient of the outdoor heat exchanger 01. In order to save costs, the indoor heat exchanger 02 with a large heat transfer coefficient is usually designed to have a smaller heat transfer area, which will result in a difference in the volume of the two heat exchangers. Larger, the amount of refrigerant required to exert the best performance in cooling and heating is also different. However, since the gas-liquid separator 03 in the system does not have th...
