Problems solved by technology

[0003] The traditional heat recovery method is to connect a hot water heat exchanger in series between the compressor and the condenser of the chiller for heat recovery. When the compressor of the chiller is equipped with an oil separator, after the compressor A hot water heat exchanger in series for heat recovery will make the temperature of the oil and refrigerant mixture entering the oil separator too low, and the oil separator cannot fully separate the lubricating oil and refrigerant, resulting in the lubrication of the return compressor There is refrigerant liquid in the oil and the compressor is damaged, or a large amount of lubricating oil enters the heat exchanger with the refrigerant liquid, causing the compressor to burn out due to serious oil leakage

Embodiment Construction

[0015] Shown in accompanying drawing 1 is an embodiment of the heat recovery chiller, the heat recovery chiller is composed of a compressor 1, an oil separator 2, a hot water heat exchanger 3, a condenser 4, a throttling device 5, and an evaporator 6 and connecting pipelines, etc., wherein the hot water heat exchanger 3 is connected in series between the oil separator 2 and the condenser 4. The high-temperature refrigerant gas coming out of the oil separator 2 enters the hot water heat exchanger 3, exchanges heat with the application water flowing through the heat exchanger 3, is initially cooled and enters the condenser 4; The application water absorbs the heat of the high-temperature refrigerant and then heats up and outputs it as domestic or production hot water. The hot water heat exchanger adopts any one of plate type, shell and tube type and casing type.

[0016] Shown in accompanying drawing 2 is another embodiment of the heat recovery chiller, which mainly consists of...

Abstract

It relates to a heat return cooling machine set. It adds a hot water heat exchanger for heat recovery, with reduced running cost, and pollution to environment of condensation, avoiding traditional issue of bad separation of oil and gas mixture, with safe and reliable running.

Description

technical field [0001] The invention relates to a heat recovery chiller, which belongs to the technical field of air conditioning. Background technique [0002] As we all know, chillers discharge a large amount of condensation heat through the cooling water system during operation, which increases the ambient temperature of the building and causes serious environmental thermal pollution. Moreover, due to the increase in ambient temperature, the working environment of the chiller has also deteriorated, resulting in a decrease in the COP of the unit and an increase in energy consumption of the air conditioner; for hotels, factories and other places that require a large amount of hot water supply every day, the conventional method is to use boilers to produce Hot water, the annual primary energy consumption of hot water production is very huge, and the emission of combustion exhaust gas causes serious pollution to the environment. Therefore, if the recovery of condensation hea...
