Embodiment Construction

[0035] The novel high-efficiency energy ladder using closed-cycle central air-conditioning system of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0036] The new high-efficiency energy ladder uses a closed-cycle central air-conditioning system of the present invention, including: a refrigeration cycle system, which is used to circulate and cool down the chilled water required by the user end through heat exchange;

[0037] The domestic water system is connected in parallel with the cooling water pipeline at the end of the refrigeration cycle system through the heat exchange device, and is used to exchange the heat generated by the normal temperature domestic water with the cooling water pipeline at the end of the refrigeration cycle system, and then convert the domestic water heat up;

[0038] The cooling tower is connected to the end of the cooling water pipeline at the end of the refrigeration cyc...

Abstract

A novel efficient closed-type cycle central air conditioner system with energy used in a stepped mode comprises a refrigerating cycle system, a domestic water system and a cooling tower, wherein the refrigerating cycle system is used for cycling and cooling chilled water needed by a user side through heat exchange; the domestic water system is connected with a cooling water pipeline of the refrigerating cycle system in parallel through a heat exchange device and is used for warming domestic water after conducting heat exchange on the domestic water with the normal temperature and heat produced by the cooling water pipeline at the tail end of the refrigerating cycle system; the cooling tower is connected after the cooling water pipeline at the tail end of the refrigerating cycle system and the domestic water system carry out heat exchange and is used for discharging a part of redundant waste heat of the cooling water pipeline at the tail end of the refrigerating cycle system after the refrigerating cycle system and the domestic water system carry out the heat exchange, and maintaining safe operation of the whole system. The novel efficient closed-type cycle central air conditioner system with the energy used in the stepped mode enables the energy to be used in a multi-stepped mode, the closed-type cycle with waste heat utilization is formed, heat discharge is reduced, heat efficiency is improved, emission and pollution to the environment are reduced, and energy is saved.

Description

technical field [0001] The invention relates to a central air-conditioning system. In particular, it relates to a new type of high-efficiency energy ladder using a closed-cycle central air-conditioning system. Background technique [0002] The central air-conditioning system has a host and a terminal system. According to the media used to bear the indoor heat and humidity load, it can be divided into all-air systems, all-water systems, air-water systems, and refrigerant systems. According to the degree of concentration of air handling equipment, it can be divided into centralized and semi-centralized. According to the source of the treated air, it can be divided into closed type, direct flow type and mixed type (primary return air and secondary return air). The main components are air-conditioning host (cold and heat sources), wind cabinets, fan coils, and so on. [0003] The basic working process of the cold (hot) water unit is: the outdoor refrigeration (heat) unit coo...
