Embodiment 1

[0022] Embodiment 1: The capacity adjustment system for heat pump units is installed in parallel on the connecting pipe of the first liquid reservoir 7 and the water-cooled condenser 3, and it is composed of the second liquid reservoir 4 and the solenoid valve 5, wherein the second The inlet of the accumulator 4 is connected to the outlet of the water-cooled condenser 3, and its outlet is connected to the inlet of the first accumulator 7 through the solenoid valve 5; when the system is controlled, only the solenoid valve 5 is powered off to realize regulation, and the air For source heat pumps, when the ambient temperature is higher than 25°C (reference temperature), the solenoid valve 5 is powered off and closed, and in other cases (including defrosting) the solenoid valve 5 is powered on and opened; the second liquid reservoir 4 is specially made, which is different from Conventional high or low pressure accumulators, the inlet of this second accumulator 4 is at the top posit...

Abstract

A volume adjuster is used in heat pump and connected to the connecting tube of liquid storage device and water-cooling condenser. The invention is characterized in that: the system is formed by a special liquid storage device and an electromagnetic valve. The inlet of storage device is connected with the outlet of water-cooling condenser, while the outlet via the electromagnetic valve is connected with the inlet of storage device. The electromagnetic valve can be replaced with the servo adjusting valve which can adjust the opening degree via the change environment temperature or other parameters. The inlet of storage device is at the top while the outlet is at the bottom, wherein, the diameter of entrance is same as the diameter of inlet tube of expanding valve. The invention has wide application in heat pump water heater and heat pump air conditioner.

Description

technical field [0001] The invention relates to a capacity adjustment system, in particular to a refrigerant circulation capacity adjustment system used in a heat pump unit. Background technique [0002] Since the amount of refrigerant required by the heat pump (hot water machine) system changes with the temperature of the heat source, such as an air source heat pump water machine, the heat source is ambient air, and the ambient air temperature varies greatly throughout the year (-10 to 45°C This makes the internal demand of the heat pump system also vary greatly, with more demand in winter and less demand in summer. [0003] At present, for a heat pump (hot water) unit that has been finalized, the final charge of the system is determined and greatly affected by the high temperature condition, that is, in order to ensure that the unit operates at a higher ambient temperature (such as 35-40°C) or heat source In order to make hot water normally and stably under the condition ...
