The utility model is achieved through the following technical solutions: a kind of variable refrigerant volume parallel connection type " steaming cold type " temperature adjusting and dehumidifying unit that is applicable to underground engineering, comprise compressor, evaporative condenser, air-cooled condenser, evaporimeter and throttling arrangement that underground engineering is provided with, compressor, ratio three-way control valve, evaporative condenser, air-cooled condenser, evaporimeter and throttling arrangement connect into a kind of refrigeration cycle by refrigerant line; An end of evaporative condenser and air-cooled condenser and connect the ratio three-way control valve wherein, evaporative condenser and air-cooled condenser other end exit are installed check valve and also are connected to throttling arrangement; Be provided with the cold-producing medium fluid reservoir, refrigerant line connects compressor suction by fluid reservoir.

Described threeway ratio adjusting valve is the ratio adjusting valve that the flow of two outlets of control valve is regulated continuously.

Evaporative condenser places underground engineering inside, utilizes the wet carrying capacity of heat of air draft to take condensation heat out of underground engineering.

Evaporimeter is connected on the return air pipeline with air-cooled condenser, and return air carries out adjustment through air-cooled condenser behind the evaporimeter dehumidifying and cooling.The condensed water that evaporimeter produces after water-collecting tray is collected, enters in the header tank of evaporative condenser.

1, system forms: the utility model system is made up of compressor, evaporative condenser in parallel and air-cooled condenser, reservoir, throttling arrangement, the evaporimeter of connecting with air-cooled condenser and threeway ratio adjusting valve, check valve etc., reaches the temperature adjustment purpose by the flow through refrigerant flow of two condensers of adjusting.

2, kind of refrigeration cycle: the high-temperature high-pressure refrigerant that comes out from compressor enters evaporative condenser and air-cooled condenser through the threeway ratio adjusting valve successively, enter fluid reservoir through check valve, be back to compressor through throttling arrangement, evaporimeter, finish a kind of refrigeration cycle.

3, apparatus for evaporation condensation: utilize the wet carrying capacity of heat of the inner air draft of engineering,, take waste heat out of engineering by the spray evaporation of water.Condensed water drains into evaporative condenser bottom header tank through water-collecting tray with gravity or machinery as the part of circulating cooling make-up water.

Automatic temperature-regulator: measure the air-cooled condenser leaving air temp by temperature survey and adjusting device, and compare with design temperature, if the temperature difference is outside prescribed limit, then regulate the electric three passes adjusting device, the assignment system refrigerant flow drops on up to measured temperature within the scope of regulation through the ratio of two condensers.

Evaporative condenser is coiled (pipe, elliptical tube or shape tube), board-like, material filling type or bubble type evaporative condenser, and the adjustable joint of shower water flow is to realize the adjusting to condensing pressure; Place engineering inside,,, increase the barrier propterty of engineering simultaneously with the wet carrying capacity of the heat that makes full use of air draft with the shared blower fan of air draft.The triple valve rate of discharge can be regulated continuously, and the flow distribution of refrigerant ratio that flows to two condensers by adjusting realizes adjustment.

The beneficial effects of the utility model are: provide evaporative condenser freezing temperature adjusting and dehumidifying unit, and especially a kind of water saving, energy-conservation, safe, the temperature adjusting and dehumidifying unit that compatibly descends engineering characteristic, dehumidifying, temperature adjusting and dehumidifying and freeze drying function can realize heating up.As higher when the inner humidity load of engineering, but temperature is when low, and the cold-producing medium of HTHP reaches the dehumidifying purpose that heats up all by the air-cooled condenser cooling.
