Small-sized central cold and warm air-conditioner capable of supplying hot water

Abstract

The invention discloses a small-sized central cold and warm air-conditioner capable of supplying hot water. The small-sized central cold and warm air-conditioner comprises a box body, a compressor, condensers, a pressure reducing valve and evaporators, wherein the compressor, a three-way tube, an electromagnetic valve, a one-way valve, a drying filter, a capillary tube, an evaporator and an axial flow fan which is arranged beside the evaporator are arranged at the lower layer of the box body; the upper layer of the box body is a heat insulating box with a heat insulating layer; the heat insulating box is partitioned into a high temperature water bucket, a low temperature water bucket and a cold and heat energy storage bucket; a hot water outlet, a condenser and a one-way valve are arranged in the high temperature water bucket; a condenser and a three-way tube and a one-way valve are arranged in the low temperature water bucket; an ice kettle, a condenser, an evaporator, a drying filter, an electromagnetic valve, a capillary tube as well as an anti-freezing liquid inlet and an anti-freezing liquid outlet which are formed in the bucket wall are arranged in the cold and heat energy storage bucket; and an anti-freezing liquid pump, a heat exchanger, a centrifugal fan and an air tube are arranged on the left side of the box body. By using the small-sized central cold and warm air-conditioner disclosed by the invention, the electric energy consumption is reduced and energy efficiency ratio and energy utilization rate are increased.

Description

technical field [0001] The invention relates to related products of air conditioners, in particular to a small heating and cooling central air conditioner capable of supplying hot water. Background technique [0002] At present, in the existing technology of heating and cooling air conditioners using the four major components of the refrigeration system (compressor, condenser, pressure reducing valve, and evaporator) and Freon, the design requirements for the cooling capacity of the air conditioner refrigeration system are relatively high, and the power consumption is relatively high. The heat generated by the air conditioner during the refrigeration process is often exhausted to the outside through the exhaust fan of the condenser. This part of the heat that is roughly equal to the cooling capacity has not been utilized, which not only affects the surrounding air environment, but also is a great waste from the perspective of energy utilization. One of the reasons for the h...

Problems solved by technology

This part of the heat, which is roughly equal to the cooling capacity, has not been utilized, which not only affects the surrounding air environment, but also is a great waste from the perspective of energy utilization. One of the reasons for the high energy consumption is obviously incompatible with the requirements of vigorously advocating energy conservation and environmental protection, and reducing energy consumption.
