Embodiment Construction

[0053] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0054] Such as figure 1 As shown, an integrated device 100 for a heat pump includes: an economizer 200 , an oil heater 300 , and an oil cooler 400 . Wherein the economizer 200 is a flash type economizer. The integrated device 100 also includes an oil separator 500 arranged at one end of the flash economizer. And the shell-and-tube heat exchanger 600 located at the other end of the flash economizer.

[0055] The flash economizer has a first filter screen 210, which divides the interior of the flash economizer into upper and lower spaces. It also has a first liquid inlet 220, a first liquid outlet 230, and a first air outlet 240, wherein the first liquid inlet 220 and the first liquid outlet 230 are located below the first filter screen 210, and the first air outlet 240 Located above the first filter scree...

Abstract

The invention discloses an integrated device for a heat pump, which includes: an economizer, an oil heater, and an oil cooler, the economizer is a flash type economizer, and the oil heater and the oil cooler are both arranged on In the flash economizer. The integrated device for the heat pump disclosed by the present invention adopts a flash economizer, and its heat exchange efficiency is high; The oil temperature and the oil temperature after cooling by the oil cooler are close to the temperature in the flash economizer, neither too high nor too low, which can ensure the safe, stable and efficient operation of the heat pump.

Description

technical field [0001] The invention relates to a heat pump system, in particular to an integrated device for a heat pump. Background technique [0002] Economizers, oil coolers, and oil heaters are common components of heat pumps, but the existing low ambient temperature air source heat pumps mainly have the following problems: [0003] (1) The economizer adopts a plate heat exchanger, which has poor heat exchange efficiency; [0004] (2) The oil heater is placed in the condenser, and the heated oil temperature is close to the condensation temperature of the heat pump, which excessively raises the oil temperature and affects the safe, stable and efficient operation of the heat pump; [0005] (3) The oil cooler is cooled separately by refrigerant, etc., and the cooled oil temperature is close to the evaporation temperature of the heat pump, which reduces the oil temperature too much and affects the safe, stable and efficient operation of the heat pump. Contents of the inv...
