Sub-cooling condenser

Abstract

The invention relates to the technical field of refrigerating air conditioners, in particular to a sub-cooling condenser used in a water source heat pump unit. The sub-cooling condenser mainly solves the technical problems of low sub-cooling degree and low energy efficiency ratio of a condenser used in the water source heat pump unit in the prior art. The sub-cooling condenser comprises a barrel; a front tube plate and a rear tube plate are respectively arranged at the front and rear ends of the barrel; the front and rear tube plates are respectively connected with a front tube box and a rear tube box; the front tube box is provided with a water inlet and a water outlet; a plurality of condensation pipes are arranged in the barrel; an oil separator is arranged inside the barrel, positioned on the upper part of the barrel and communicated with an air inlet pipe assembly; the joint of the oil separator is connected with an oil return port connecting pipe of the barrel; and a sub-cooling pipe is arranged inside the barrel at the water inlet, supported through a sub-cooling pipe baffle plate and connected with the front tube plate and the rear tube plate in an expanded mode. A liquid outlet partition plate is arranged in the barrel, and a coolant flow passage from a condensation section to a sub-cooling section is established, so that the condensed saturated liquid is separated from the sub-cooling liquid.

Description

technical field [0001] The invention relates to the field of refrigeration and air conditioning, in particular to a subcooling condenser used in a water source heat pump unit. Background technique [0002] The water source heat pump unit is a cooling and heating product with relatively high energy efficiency in the current air-conditioning chiller unit. The internal condenser is a key component of the refrigeration system. A device that converts refrigerant gas or vapor into a liquid. A Chinese patent discloses an air-source water-source heat pump hot water unit (authorized announcement number: CN201964610U), which includes an air-source heat pump device using a low-temperature refrigerant and a water-source heat pump device using a high-temperature refrigerant; the air-source heat pump device includes a first compressor machine, a heat exchange device in the condensing evaporator, the first throttling device, and a heat exchanger capable of exchanging heat with outdoor air...

AI Technical Summary

Problems solved by technology

However, the condenser used in this water source heat pump unit has the same saturation temperature in all condensation processes, so there is not enough subcooling, the subcooling degree is low, and the energy efficiency is relatively low.
