Abstract
The utility model discloses an efficient water chiller which comprises a compressor, a condenser, an electronic expansion valve and an evaporator, wherein the compressor, the condenser, the electrical expansion valve and the evaporator are sequentially connected through pipelines in an end-to-end mode and form a circulation loop. An economizer is further arranged between the condenser and the electronic expansion valve and used for heat exchange between a refrigerant which is already condensed through the condenser, and another refrigerant which already passes through a throttle valve, and a first refrigerant outlet of the economizer is communicated on the evaporator through the electronic expansion valve. According to the efficient water chiller, the fluid refrigerant at an outlet of the condenser can be cooled once again, the degree of supercooling of the refrigerant is improved, and therefore the refrigerating capacity and the energy efficiency ratio of a system are increased.

Technical field
The utility model relates to a kind of energy saving, belongs to the cold/hot water unit design and makes the field.
Background technology
The cold/hot water unit normally transfers by cold-producing medium circulating in the loop that is comprised of compressor, condenser, expansion valve, evaporimeter etc. and realizes refrigeration or heat.
for example, Chinese patent literature CN2529160Y discloses a kind of evaporative condenser handpiece Water Chilling Units, comprise compressor, condenser, expansion valve, evaporimeter, described compressor, condenser, expansion valve, evaporimeter is airtight connection successively, make refrigerant cycle operation therein, described condenser casing is a casing, be provided with condenser coil in casing, condenser coil is snakelike coiling, the one end is connected with compressor, the other end is connected with expansion valve, in casing condenser coil below be provided with cistern, be provided with watering device around condenser coil in casing, be provided with fortune water device between cistern and watering device, be provided with air inlet on the box body wall above cistern, the corresponding air outlet that also is provided with.In above-mentioned evaporative condenser handpiece Water Chilling Units, the cyclic process of cold-producing medium is: the cold-producing medium of gaseous state is discharged by compressor, enter condenser condenses and become liquid, then be divided into two-way, one the tunnel enters evaporimeter after the expansion valve throttling, be that gaseous refrigerant returns compressor through evaporator evaporation, compressor is directly got back on another road.Above-mentioned evaporative condenser handpiece Water Chilling Units is simple in structure, but the gaseous refrigerant of being discharged by compressor only passes through condenser condenses, and condensed liquid refrigerant degree of supercooling is not high, and refrigerating capacity and the Energy Efficiency Ratio of system are unsatisfactory.
The utility model content
Therefore, it is only not high by the condenser condenses degree of supercooling that technical problem to be solved in the utility model is to overcome in prior art handpiece Water Chilling Units, cause the lower problem of cooling system amount and Energy Efficiency Ratio, so provide a kind of can be with the liquid refrigerant of condensator outlet cooling, the energy saving that improves the degree of supercooling of cold-producing medium again.
For this reason, the utility model provides a kind of energy saving, comprise the compressor, condenser, electric expansion valve and the evaporimeter that connect successively and form closed circuit by the pipeline head and the tail, also be provided with economizer between described condenser and described electric expansion valve, the cold-producing medium of described economizer after with described condenser condenses with carry out heat exchange through the cold-producing medium after choke valve, the first refrigerant outlet of described economizer is communicated on described evaporimeter by described electric expansion valve.
The second refrigerant outlet of described economizer is communicated to the economizer interface of described compressor, and described compressor tonifying Qi is increased enthalpy.
The outlet of described condenser is communicated to described compressor, and is cooling to described compressor.
Described economizer is tubular type economizer or board-like economizer.
